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 our count of every school day against the day counts the district prints. They match.
Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
