Corrections

Every rule we corrected in the dates and labels on this site, newest first, with one district or page that showed it: what the page said, what it said after the fix, why it was wrong, the rule we changed so that every district read the same way was corrected with it, and how many districts or pages that rule changed, where we counted  it.

  1. October 20, 2026 · Davie County, North Carolina

    What
    First day of school
    Before
    August 6, from “Early College First Day of School!”.
    After the fix
    August 24, from “First Day of School!”.
    Why it was wrong
    The first day of a single early college high school, which starts before the rest of the district, was read as the first day for the whole district.
    Rule changed
    A date marked for an early college (“Early College”, “ECHS”) belongs to that one school, not to the district.
    Changed by this rule
    1 district page, and the national and state first-day pages that count it
  2. October 20, 2026 · Chatham County, North Carolina

    What
    First day of school
    Before
    August 6, from “First Day of School for Chatham Early College”.
    After the fix
    August 25, from “First Day of School”.
    Why it was wrong
    The first day of a single early college high school, which starts before the rest of the district, was read as the first day for the whole district.
    Rule changed
    A date marked for an early college (“Early College”, “ECHS”) belongs to that one school, not to the district.
    Changed by this rule
    1 district page, and the national and state first-day pages that count it
  3. October 20, 2026 · Nuview Union, California

    What
    First day of school
    Before
    August 5, from “Nuview Bridge ECHS: First Day of School”.
    After the fix
    August 12, from “First Day of School: Students in TK-8”.
    Why it was wrong
    The first day of a single early college high school, which starts before the rest of the district, was read as the first day for the whole district.
    Rule changed
    A date marked for an early college (“Early College”, “ECHS”) belongs to that one school, not to the district.
    Changed by this rule

  4. October 20, 2026 · Warren County, North Carolina

    What
    First day of school
    Before
    August 10, from “First Day of School for Students (WECHS)”.
    After the fix
    August 24, from “First Day of School for Students”.
    Why it was wrong
    The first day of a single early college high school, which starts before the rest of the district, was read as the first day for the whole district.
    Rule changed

  5. October 13, 2026 · Fall break by state

    What
    How many districts have a fall break
    Before
    “week of October 12–16 for 119 of the 233 districts that list one (51%) … Of the 989 districts we read, 233 list a fall break.”
    After the fix
    “week of October 12–16 for 126 of the 252 districts that have one (50%) … Of the 989 districts we read, 252 have a fall break: 233 call it that; the other 19 are 3 or more school days off in a row.”
    Why it was wrong
    Only closures the district names for the fall were counted, so 19 districts that close for three to five school days in the fall had no fall break on this page.
    Rule changed
    A national page says how many of the districts we read have a fall break, and how many of those the district itself calls fall break.
    Changed by this rule
    1 national page, with “At least four in five have one” and “None has one” in its table of states
  6. October 13, 2026 · Fall break in Pennsylvania

    What
    How many districts have a fall break
    Before
    “Only one of the 75 Pennsylvania districts we read lists a fall break in 2026: School District of Lancaster (October 9–13).”
    After the fix
    “Only 2 of the 75 Pennsylvania districts we read have a fall break in 2026: Berwick Area (September 30 to October 2) and School District of Lancaster (October 9–13). Berwick Area does not call it fall break: it is 3 school days off in a row.”
    Why it was wrong
    Berwick Area closes its schools from Wednesday, September 30 to Friday, October 2 (“Schools Closed”). With only named fall breaks counted, the page left it out, and its words said “lists”, which fits only a break the district names.
    Rule changed
    A page that counts fall breaks says “have a fall break”, and says which of them the district does not call fall break. A fall break is a closure the district calls fall or autumn break, or, under any name, a closure for all students of three or more school days in a row starting between September 15 and November 15, outside Thanksgiving week.
    Changed by this rule
    5 state pages that give the share (California, Illinois, Kansas, Ohio, Pennsylvania) and 7 state fall break pages with a new line “Called fall break by the district”
  7. October 13, 2026 · Killeen Independent, Texas

    What
    Fall break
    Before
    “No school”, October 12–16, 2026, 5 school days, in the district’s words “Staff & Student Holiday”, and no fall break anywhere on the page.
    After the fix
    “Fall break”, October 12–16, 5 school days, still in the district’s own words “Staff & Student Holiday”; the date strip reads “Fall break + 1 more day off, October 12–19”.
    Why it was wrong
    On October 9 we began to count as a fall break only a closure the district itself names for the fall, so a whole week with no school for any student, which the district calls a student holiday, was shown as an ordinary day off.
    Rule changed
    A fall break is a closure the district calls fall or autumn break, or, under any name, a closure for all students of three or more school days in a row starting between September 15 and November 15, outside Thanksgiving week; Columbus Day, Veterans Day and Election Day do not count toward the three. A Friday and a Monday off are still two days off, not a fall break.
    Changed by this rule
    19 district pages (in Texas also Lorena, Big Sandy, Burton, Garrison, Thrall and Weatherford); districts with a fall break 232 → 251
  8. October 9, 2026 · Florham Park, New Jersey

    What
    Source of the dates
    Before
    Dates read from hanoverpark.org, the site of the Hanover Park Regional High School District, and shown as the Florham Park School District’s own on an indexed page: 11 dates, among them a last day of school on June 21 and graduation on June 23, 2027.
    After the fix
    The district is removed until a calendar published by the Florham Park School District itself is available; its address redirects to the New Jersey page.
    Why it was wrong
    The address in our list of New Jersey districts was the site of another school district, the grades 9–12 district that Florham Park’s high-school students attend. Its calendar has a freshman day, AP testing, homecoming and graduation, which a K–8 district does not hold.
    Rule changed
    A calendar that is not the district’s own, including another school district’s, is not published, and a site whose name matches another district in our state list, and not the district itself, is checked by hand before it is published.
    Changed by this rule
    1 district page removed
  9. October 9, 2026 · Fall break by state

    What
    Share of districts
    Before
    “week of October 12–16 for 140 of the 275 districts we read (51%)”, while 991 districts were read and 275 of them list a fall break.
    After the fix
    “week of October 12–16 for 119 of the 233 districts that list one (51%) … Of the 989 districts we read, 233 list a fall break.”
    Why it was wrong
    Shares were counted among the districts that list the break, and the words said “districts we read”.
    Rule changed
    A share says what it is counted from; a national page says how many of the districts read list the break.
    Changed by this rule
    6 national pages
  10. October 9, 2026 · School on Labor Day

    What
    Answer
    Before
    “Mostly no.” with 890 of 890 districts closed.
    After the fix
    “No.” with 888 of 888 closed.
    Why it was wrong
    The answer word came from thresholds (70% and above: “Mostly no”), even when every district was closed.
    Rule changed
    Every district closed: “No.”; none closed: “Yes.”; 70% or more: “Mostly no.”; 30% or less: “Mostly yes.”; otherwise “Depends on the district.”
    Changed by this rule
    1 of 5 holiday pages
  11. October 9, 2026 · Lewis-Palmer School District 38, Colorado

    What
    Winter break
    Before
    December 17 to January 1, starting with “Last Day for Students Before Winter Break”.
    After the fix
    December 21 to January 1; December 17 is a school day, and December 18 (“No Classes, PLC Workday, Alternative Make-up Day”) is its own row.
    Why it was wrong
    The words “winter break” in “Last Day for Students Before Winter Break” were read as the break itself.
    Rule changed
    A last day before a winter, spring, fall or Thanksgiving break is a school day.
    Changed by this rule
    3 districts
  12. October 9, 2026 · Fall break in Pennsylvania

    What
    How many districts list a fall break
    Before
    “Only 4 of the 75 Pennsylvania districts we read list a fall break”, while three of the four, Berwick Area (“Schools Closed”), Cumberland Valley and Penn Manor (“No School”), do not call those days a fall break.
    After the fix
    “Only 1 of the 75 Pennsylvania districts we read lists a fall break in 2026: School District of Lancaster (October 9–13).”
    Why it was wrong
    A closure in the fall made only of general words, often a Friday and a Monday or two separate entries, was named a fall break by its place in the year.
    Rule changed
    A fall break is a closure the district itself names for the fall (fall, autumn, Fall Intersession). Other days off in the fall keep the district’s words and the label “No school”.
    Changed by this rule
    49 districts; districts with a fall break 274 → 232
  13. October 9, 2026 · Penn Manor, Pennsylvania

    What
    Spring break and the end of the calendar
    Before
    Spring break March 24–25, from “No School/Weather Make-up Day”, and a partial calendar whose “published dates end on March 25, 2027”.
    After the fix
    Read again on October 9, 2026: spring break March 26–29 (“No School (Spring Break)”), last day of school June 3, 2027; the calendar is complete.
    Why it was wrong
    Our reader of WordPress calendars stopped after 30 pages of 50 events. Penn Manor’s feed, which carries the district’s and its schools’ sports calendars, is longer, so nothing after March 25 was read, and the partial-calendar notice said the district’s dates ended there.
    Rule changed
    A feed is read to its last page; a feed longer than our page limit is a failed read and keeps the earlier dates. A partial calendar says where the calendar we read ends, not where the district’s dates end.
    Changed by this rule
    1 district read again (no other WordPress feed reached the limit); the notice wording changed on all 87 partial calendars (48 of them in search results)
  14. October 9, 2026 · Ligonier Valley, Pennsylvania

    What
    Spring break
    Before
    March 25–30, 4 school days, including “Spring Break - No School (Snow Makeup #3)” on March 25 and “(Snow Makeup #4)” on March 30.
    After the fix
    Spring break March 26–29, 2 school days; March 25 and March 30 are their own “No school” rows, in the district’s words.
    Why it was wrong
    Days the district may use to make up snow closures were joined to the break next to them, and counted as days of the break.
    Rule changed
    A day the district may turn into a school day (a snow, weather or emergency make-up day, “if needed”) is never part of a break: it keeps its own row, the break’s dates and the date strip leave it out, and a break the district dates across it is cut there.
    Changed by this rule
    42 break rows in 35 districts
  15. October 9, 2026 · Beaumont Unified, California

    What
    District’s own wording
    Before
    “8 | Early Release School Day”, on every Wednesday of the year.
    After the fix
    “TK - 8 | Early Release School Day”, as the district writes it.
    Why it was wrong
    A short capital code before a dash is taken as a school’s code and removed, and “TK”, transitional kindergarten, was removed with it from the grade range.
    Rule changed
    A code before a dash is removed only when no grade number follows it.

  16. October 9, 2026 · Taconic Hills Central, New York

    What
    September 30, October 1, November 2 and December 1
    Before
    “End of semester”, from “Last Day Non-Penalty School Tax Payments Accepted” and two other tax deadlines.
    After the fix
    No label of ours: the district’s own words only.
    Why it was wrong
    A “last day” in the autumn was read as the end of a term.
    Rule changed
    A last or first day for taxes, payments, fees or tuition is a deadline, not a school date.
    Changed by this rule
    4 entries in 1 district (the October 1 entry is kept from the September 29 read)
  17. October 9, 2026 · Socorro Independent, Texas

    What
    Fall break
    Before
    “Fall Intersession”, September 26 to October 11, with no label of ours: not counted, and no fall break on the page.
    After the fix
    “Fall break”, September 26 to October 11, 10 school days.
    Why it was wrong
    “Spring Intersession” was read as a spring break, and “Fall Intersession” was not read at all.
    Rule changed
    A district’s “Fall Intersession”, “Fall Holiday” or “Fall Holidays” is its fall break.
    Changed by this rule
    7 districts
  18. October 9, 2026 · Geneseo Community Unit School District 228, Illinois

    What
    September 30
    Before
    “Teacher work day, no students”, 1 school day, from “Half-Day Teacher Inservice (11:40am dismissal)”.
    After the fix
    “Early release”: students are in school until 11:40.
    Why it was wrong
    A dismissal time counted as an early release only when it was written with “pm”.
    Rule changed
    An entry with a dismissal time for students, in the morning, without am or pm, or after “Dismiss” or “Dismiss at”, is an early release, not a day off.
    Changed by this rule
    21 entries in 9 districts
  19. October 9, 2026 · School District of Manatee County, Florida

    What
    March 26
    Before
    “Good Friday - All sites closed.” with no label of ours, not counted as a day off.
    After the fix
    “No school”, counted as a day off.
    Why it was wrong
    Our closure words did not include “all sites closed”, and a named holiday such as “Good Friday Holiday” or “Lincoln’s Birthday Holiday” was read only when the word “Holiday” came first.
    Rule changed
    “All sites closed” is a closure, and a named holiday followed by “Holiday” (Good Friday, Lincoln’s Birthday, Cesar Chavez, a local holiday, a student and teacher holiday) is a day off.
    Changed by this rule
    24 entries in 19 districts
  20. October 9, 2026 · Enid Public, Oklahoma

    What
    August 31
    Before
    “Testing”, from “Kim Collins ACT Classes”.
    After the fix
    No label of ours: the district’s own words only.
    Why it was wrong
    Any “act” in the wording was read as the ACT test, including ACT preparation classes, “Literacy/Math Act” and “One-Act Play”.
    Rule changed
    A test day is the ACT, SAT, PSAT or a named state test on that day; “ACT” counts only in capitals, and a class or course that prepares for a test is not a test day.
    Changed by this rule
    64 entries in 33 districts
  21. October 9, 2026 · Cambria Heights, Pennsylvania

    What
    October 12
    Before
    “Testing”, from the district’s “Act 80 Day - No School”: not counted as a day off, “Next time off” showed November 10, and the Columbus Day page listed the district as “not in the calendar we read”.
    After the fix
    “No school”, counted in “School days off this year”; “Next time off” shows October 12 as of the October 8 read, and the Columbus Day page lists the district as closed.
    Why it was wrong
    Our test label matched “ACT” in “Act 80”, the Pennsylvania law under which districts hold days without students, and a test, quarter-end or conference label won over the district’s own words “No School”.
    Rule changed
    An entry whose own words say there is no school, no students or classes, or that schools, all sites or the district are closed for the whole day, is a day off, whatever milestone it also names. A part day (afternoon, half day, a dismissal time) stays an early release; a closure for some grades or schools stays theirs.
    Changed by this rule

  22. October 9, 2026 · Fall break in Texas

    What
    Read date
    Before
    “147 districts read on September 29, 2026” above the title, “read from its own calendar on Sep 29” in the search description, “Snapshot September 29, 2026” in the footer and September 29, 2026 as the page date in its markup, while all 147 Texas districts were read on October 8.
    After the fix
    “147 districts read on October 8, 2026”, “read from its own calendar on Oct 8”, “Read on October 8, 2026” in the footer and October 8, 2026 as the page date.
    Why it was wrong
    Every page that counts districts printed the site’s snapshot date, the earliest read of any district in our set. Dallas School District, Pennsylvania, a district with no page, held it at September 29: its robots.txt forbids the address our reader requests (it has a query string), so it was not read again, and a second robots.txt check, run on the address without the query, had cleared it, so its September 29 dates stayed in the set.
    Rule changed
    A page that counts districts gives the days those districts were read: one day, or the first and the last. robots.txt is checked against the full address our reader requests, query string included, and a source it forbids is neither published nor kept from an earlier read. The site’s snapshot date is the earliest read of the districts that have a page.
    Changed by this rule
    The footer of all 1,294 pages; the line above the title of 288 state, state topic, national and holiday pages; 1 district removed from the set (Dallas School District, Pennsylvania, no page)
  23. October 8, 2026 · Hillsborough County Public, Florida

    What
    Source of the dates
    Before
    Dates read from hillsboroughcta.org, the site of the Hillsborough Classroom Teachers Association — the teachers’ union, not the district — and shown as the district’s website: 49 dates for 2026–2027 on the district page, in the Florida tables and in the national counts.
    After the fix
    The district is removed until a calendar published by the district itself is available.
    Why it was wrong
    The address in our list of Florida districts was the teachers’ union site. Its calendar lists the district’s dates next to union events such as “Members Only Townhall Webinar” and “Summer Rep Training”.
    Rule changed
    A calendar read from a site that is not the district’s own, such as a teachers’ union or a city, is not published, and it stays out when calendars are read again.
    Changed by this rule
    2 districts: Hillsborough County Public Schools, Florida, and Tukwila School District, Washington, read from the City of Tukwila site and never on a district page of its own. 1 district page removed; changed: the 8 other Florida district pages, the Florida hub and its 5 topic pages (the spring break page left search results: 7 districts list one), 15 national pages, the Washington hub, and the home, About, Methodology and Terms pages
  24. October 8, 2026 · Socorro Independent, Texas

    What
    Spring break
    Before
    Spring break + 5 more days off, March 13–29.
    After the fix
    Spring break, March 13–29, 11 school days.
    Why it was wrong
    Two entries in a row, “Spring Intersession” and “Spring Intersession / District Closure”, with no school day between them, were shown as a break plus more days off.
    Rule changed
    Days of a second entry of the same kind next to a break count as part of that break, not as more days off.

  25. October 8, 2026 · Beaumont Unified, California

    What
    District’s own wording
    Before
    One row for October 9–12 with the wording of the October 9 entry, “District Closed | Observance of Federal and State Holiday”. The district’s wording for October 12, “No School | All Staff Work Day”, was not on the page.
    After the fix
    The same row with both: “District Closed | Observance of Federal and State Holiday; Oct 12: No School | All Staff Work Day”.
    Why it was wrong
    When entries were joined into one row, the row kept the wording of one of them.
    Rule changed
    A row joined from entries with different wording on different days shows each wording with its days.
    Changed by this rule

    What
    States where every district is closed
    Before
    “Every district closed: Connecticut, Louisiana, Maine, New Hampshire and Rhode Island”, with Connecticut and Louisiana read from three districts each and the other three states from a single district.
    After the fix
    Each state with the number of districts read, and the states with fewer than five read named as a small sample.
    Why it was wrong
    A state was described from one to three districts without saying so.
    Rule changed
    A statement about a state that rests on fewer than five districts is marked “small sample”.

    After the fix
    “We did not find winter break, spring break or the last day of school in the calendar we read on September 29, 2026.”
    Why it was wrong
    “Not published yet” said something about the district; we only know what the calendar we read does not contain.
    Rule changed
    A partial calendar says what we did not find in the calendar we read, and when we read it.

    What
    Longest run of school days

    44, January 19 to March 21. March 21, 2027 is a Sunday.
    After the fix
    44, January 19 to March 19.
    Why it was wrong
    A run ended on the day before the next closure, which can be a Sunday.
    Rule changed
    A run of school days ends on its last school day, and a calendar without a last day of school gives no run.
    Changed by this rule
    396 district pages: the end date changed on 263, the run was removed from 133
  29. October 8, 2026 · Alabama school calendars

    Card about fall break
    Before
    “No fall break at all: 2 districts go straight to Thanksgiving”, while Alabaster, one of the two, lists October 9, October 12 (Columbus Day) and November 11 (Veterans Day) as days off.
    After the fix
    “No fall break listed: 2 of 8 districts with a complete calendar”.
    Why it was wrong
    A district without a fall break was described as having no day off before Thanksgiving.
    Rule changed
    The card gives only the number of complete calendars without a fall break.

  30. October 8, 2026 · Michigan school calendars

    What
    Fall break card
    Before
    “Fall break: most take Oct 12–16”, while 2 of the 12 Michigan districts with a fall break have those dates.
    After the fix
    “Fall break: most common: Oct 12–16 (2 of 12)”.
    Why it was wrong
    The card said “most take” whenever two districts shared the dates.
    Rule changed
    A state card says “most take” only when more than half of the districts with that break share the dates; otherwise it gives the most common dates and their count.

  31. October 8, 2026 · Winter break in Iowa

    What
    Title and description
    Before
    “Iowa Winter Break 2026-27: Week of Dec 28” and “18 of 28 Iowa districts we read are off in the week of Dec 28, 2026–Jan 1, 2027”, while most rows of the page’s own table start December 21–24.
    After the fix
    “Iowa Winter Break 2026-27: Starts Dec 21–24” and “27 of 28 Iowa districts we read start winter break Dec 21–24, 2026”.
    Why it was wrong
    A two-week break was placed in the week holding most of its school days, so breaks that start in the same week were split between two weeks.
    Rule changed
    Winter break is grouped by the week of its first school day off, and a state page gives the dates on which those breaks start.
    Changed by this rule

    What
    “End First Grading Period” and “Start Second Grading Period”, October 16 and 19, 2026
    Before
    One entry, October 16–19, labeled End of semester, with the wording “Start Second Grading Period”.
    After the fix
    End of grading period on October 16, and New term begins on October 19.
    Why it was wrong
    Any entry with the words semester, quarter or grading period was labeled the end of a semester, and the start of a grading period was joined to its end.
    Rule changed
    The end of a quarter, grading period or trimester is labeled as such; the start of a grading period is a new term; progress reports and report cards are not term dates.

    What
    “One-Session Day - Staff PM In-Service”, June 21–22, 2027
    Before
    Teacher work day, no students: two school days off.
    After the fix
    Early release: students attend one session.
    Why it was wrong
    The word “In-Service” made the day a staff day without students, although students attend in the morning.
    Rule changed
    One-session days, half days, minimum days, “no school in the afternoon” and a set afternoon dismissal time are early releases, which are school days, unless the entry is about staff only.

    What
    “School Board Closed Session”, October 2–5, 2026
    Before
    Fall break.
    After the fix
    Not listed: it is a school board meeting, not a day off.
    Why it was wrong
    The word “closed” in the name of a board meeting read as a school closure.
    Rule changed
    A “closed session” or “executive session” is a board meeting, not a date of the school calendar.

  35. October 8, 2026 · Beaumont Unified, California

    What
    Fall break
    Before
    October 9–12, 2026, “Fall break”, from “District Closed | Observance of Federal and State Holiday” on October 9 and “No School | All Staff Work Day” on October 12.
    After the fix
    October 9–12, 2026, “No school”, with the district’s own wording.
    Why it was wrong
    Two days off the district names for other reasons were joined and named fall break by the time of year.
    Rule changed
    A closure is named fall break by the time of year only when the district’s wording is a plain “No School” or “School Holiday”, or mentions fall; it must cover at least two school days and must not be a make-up, hurricane, snow or weather day. Otherwise it is a day off under the district’s own name.

  36. October 8, 2026 · Aubrey Independent, Texas

    What
    “Student/Teacher Holiday / All Offices Closed”, March 8–12, 2027
    Before
    No school, and the page said “Spring break is not published yet.”
    After the fix
    Spring break. The calendar is complete.
    Why it was wrong
    A closure counted as spring break only when the district called it spring break or it fell between March 15 and April 20, so a full week off on March 8–12 under another name did not.
    Rule changed
    A district’s own names for a closure are read as closures: April School Vacation Break, Springs Break, Spring Intersession, Semester Break, Student/Teacher Holiday. With no spring break named, a closure of at least four school days in March or April is the spring break; with no winter break named, a closure of at least three school days over December 25 is the winter break.

  37. October 8, 2026 · Murray Independent, Kentucky

    What
    Spring break
    Before
    March 18–19, 2027, from the entry “No School”, while the district’s own “Spring Break”, April 5–9, was in the same table.
    After the fix
    April 5–9, 2027, the district’s “Spring Break”. March 18–19 is listed as “No school”.
    Why it was wrong
    The earliest closure labeled spring break won, including a two-day “No School” and Good Friday or Easter closures.
    Rule changed
    When a district calls a closure spring break, spring recess, spring vacation or spring intersession, that is its spring break. Good Friday, Easter and other “No School” closures in the spring are days off. Without such a name, the spring break is the longest closure of March and April.

    What
    Fall break
    Before
    October 9–12, made of “End Q1/Teacher Institute-No student attendance” on Friday and “Columbus Day-NO SCHOOL” on Monday.
    After the fix
    No fall break: October 9 is a day with no school and October 12 is Columbus Day / Indigenous Peoples’ Day. 13 other districts no longer show a fall break for the same reason, a separate day off next to Columbus Day: Alabaster City Schools (Alabama), Neptune City School District (New Jersey), Burkburnett Independent School District (Texas, October 12–13) and 10 more in Illinois.
    Why it was wrong
    Two separate days off, Friday and Monday, were joined into one break and named fall break by the time of year.
    Rule changed
    Columbus Day / Indigenous Peoples’ Day is a holiday type of its own, so it is no longer joined with a different day off into a break. A Columbus Day entry that covers two school days itself is still read as a fall break.

    What
    “Columbus Day/Indigenous Peoples Day / Minimum Day for students/PM Professional Development Day for Staff Only”, October 12, 2026
    Before
    Teacher work day, no students; counted as closed on the Columbus Day page.
    After the fix
    Early release; counted as open on the Columbus Day page.
    Why it was wrong
    The words about staff development decided the label before the words “Minimum Day for students”.
    Rule changed
    An entry that names Columbus Day and a minimum day or early dismissal for students is an early release, a school day.

    Before
    No label. On the Columbus Day page the district was “not in the calendar we read”.
    After the fix
    Columbus Day / Indigenous Peoples’ Day, a day off; counted as closed on the Columbus Day page.
    Why it was wrong
    Columbus Day had no type of its own, and an entry that named it with “Holiday” but without “No School” got no label.
    Rule changed
    Columbus Day / Indigenous Peoples’ Day is a holiday type of its own: an entry that names it with a word about a holiday or a closure is a day off.

    After the fix
    Fall break and one more day off, October 9–16: Columbus Day is part of the break, and the teacher day with no students on October 9 joins it.
    Why it was wrong
    Columbus Day had no type of its own, and an entry that named it with “Holiday” but without “No School” got no label.
    Rule changed
    Columbus Day / Indigenous Peoples’ Day is a holiday type of its own: an entry that names it with a word about a holiday or a closure is a day off.

    After the fix
    No time zone. Every entry is a whole day (VALUE=DATE), and a whole day has no time zone.
    Why it was wrong
    One line was written for every state.
    Rule changed
    The calendar files carry no time zone for the whole calendar; an entry with a time of day would carry its state’s time zone.

    After the fix
    Not printed. “THANKSGIVING VACATION WEEK”, November 23–27, is a Thanksgiving break, and the calendar is marked as partial: a winter break for all grades is not published yet.
    Why it was wrong
    Closures for some grades did not stop the count, and “Thanksgiving Vacation” was not recognised.
    Rule changed
    A run of school days stops at any closure, including one for some grades. “Thanksgiving Vacation” is a Thanksgiving break.

    Marked as a partial calendar: the district’s published dates end on December 18, 2026, and winter break, spring break and the last day of school are not published yet. No count or claim about the whole year.
    Why it was wrong
    The district’s published dates end in December, and the page treated them as the whole year.
    Rule changed
    A calendar is complete only with a winter break and a spring break for the whole district, a first or last day for students, and dates through April. A partial calendar makes no claim about the whole year.

    What
    Spring break

    March 15–19, and the one-day “April Break - No School” on April 23 was also shown as spring break.
    After the fix
    Spring break and one more day off, March 12–19: the parent-teacher conference day with no school on March 12 is shown with the break. April 23 is a day with no school.
    Why it was wrong
    A one-day break was named spring break by its date, and a day off right before the break was shown apart from it.
    Rule changed
    A break of one school day without the word “spring” is a day off, not spring break. A day off next to a break is shown with the break.

    Why it was wrong
    The sentence was printed for any of the top four places, whatever the number of days.

    After the fix
    Not listed: they are athletic meets, not dates of the school calendar.
    Why it was wrong
    The word “conference” alone made an entry a parent-teacher conference.

    After the fix
    Mid-winter break. The district’s own “Spring Break”, April 5–9, is its spring break.
    Why it was wrong
    The time of year named a March break spring break, over the district’s own word “Winter”.

    After the fix
    June 15, 2027, from “Last Day/Early Release (No Snow Days)”. June 23 is listed as “Last day, if needed”.
    Why it was wrong
    The strip took the latest entry named as a last day, including the one that applies only if five snow days are used.
    Rule changed
    The first and last day of school are the students’ day for the whole district. A day that depends on snow days, or one for teachers, one grade or one school, keeps its own label.
