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 each one against the OUSD Calendar page and the OUSD Website Calendar.

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