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 from August to May and the first and last day against the district's calendars page, the D181 Assessment Calendar and the district events 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.
