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 the first and last day, every day off during the school year, the eSchool days and the end of the first semester against the district's Academic Calendars page and the district's School System Events Calendar. 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.
