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 Spanish edition of the same calendar (page 2 of the PDF linked from the Aldine ISD Calendar page).
Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
