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 Roslyn calendar page, the printed 2026-2027 District Calendar and the Roslyn School District Calendar feed.
Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
