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 every day off and the first and last day against the district's Academic Calendars page and the SMUSD Website Master 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.
