• After the last day, the calendar still shows Memorial Day (May 31). Students are already out.

First and last day of school

How we checked these dates

We read every date off the district's own calendar image twice: once whole, cell by cell against its legend, and once on zoomed crops of each month. Then we checked each one against the D99 District Calendar page and the D99 full 2026-2027 school calendar.

Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
