We fetch this document again every day and compare it with the version we verified; if the district changes it, the dates here are read again.

Note: Calendar says 'revised July 2026' but does not say it was board-approved. Fall Break (Nov 23-27) and Thanksgiving Holiday (Nov 26-27) overlap: the whole week of Nov 23-27 is off for students. Winter Break starts Dec 21; Jan 1 and Jan 4-8 are shaded instructional break days; Jan 11 is a teacher day with no school; students return Jan 12. Juneteenth (observed June 18) falls after the last day. Elementary, middle and high schools have minimum (early) days marked by circles in the grid, but they differ by school level and could not be reliably read from the text, so they are not listed. Elementary parent conferences are Sep 16-18 and Nov 4-13. Middle school completion ceremonies and high school graduation dates are TBA. The document does not state instructional days.
