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 district calendars page, the district's monthly event calendar and the district's bell schedule pages.
Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
