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 Jeffco Calendar & Events page, the Spanish edition of the family calendar and the Jeffco District Calendar Dates feed.
Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
