How we checked these dates
We read every date off the district's own calendar twice: once from the PDF's text and once from the image, cell by cell against its legend. Then we checked the dates the web calendar lists (all but the Jan. 4 and 5 staff days, the Feb. 3 minimum day and Feb. 16 to 18) against the TUHSD 2026-27 School Year Calendar page and the TUHSD web calendar. The other dates rest on the district's calendar alone.
Every weekday on this page matches its date. The district's printed day counts match our own count of its calendar. If the district changes its calendar, its page is the final word.
