How K12Cal checks school district calendars
K12Cal is a reference for U.S. public school district academic calendars. It records dates from a district’s own calendar, names the source, and shows when the dates were last verified.
What gets published
A calendar page requires a first day, a last day, and the other dates the district actually published: holidays, breaks, and early-release days when they are listed. The source is the district’s calendar PDF or the district page that presents it. Each page links to that source and shows the last-verified date.
Some districts publish more than one track. When that is the case, the page names the track it covers. Wake County’s page is the traditional calendar, not the year-round or modified calendars.
What stays off the page
Dates that are unclear, contradicted by a newer district file, or taken from a third party are omitted. The page says what was left out. K12Cal does not fill a missing spring break with a typical date, and it does not turn an unverified grid mark into a holiday. A district can appear in a state directory with its website and still have no calendar page.
The state directories come from an NCES list of the 600 largest districts: name, state, city, enrollment, and website. That list is not a source of calendar dates.
Which URL is the calendar
The district page, such as /texas/cypress-fairbanks-isd/, is the reference URL for a search like “Cypress-Fairbanks ISD calendar.” It shows the current school year. The year URL, such as /texas/cypress-fairbanks-isd/2026-2027/, repeats that year’s dates. While 2026-27 is the current year, the year URL’s canonical link points at the district page so the two addresses are not competing pages. An older year kept later as an archive would stand on its own URL.
How to read a page
Start with the three facts at the top: first day, last day, and the next break as of the verification date. The table is the full set of published dates. Questions below the table answer narrower queries, such as when spring break is, using only those dates. If a note says a day is a contingency or make-up day, the district may later use it as a school day.
