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 the first and last day and every day off except Labor Day against the SMCISD District Calendar events and the SMCISD District Calendar page. The other dates rest on the district's calendar alone.
Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
