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: It replaces the 'Board Approved Calendars 2026-27 and 2027-28' file (July 2025), which the folder no longer lists; every date is the same, and the new file corrects the Important Dates box for Thanksgiving Break from 'November 24 - November 28' to November 23-27, matching the grid, the 44 days of the second grading period and the district's online calendar ('Thanksgiving Break - District Closure', November 23-27). Student Holiday/Long Range Planning days (October 12, January 4, March 15) are no-school days for students; students return from Winter Break on January 5 and from Spring Break on March 16. March 26 and May 3 are Student/Staff Holidays. The district's online calendar lists the last day, May 27, as 'Last Day of School/Early Student Release'. May 28 is a professional day after the last day. 176 student days = sum of the grading period counts printed on the calendar (39 + 44 + 42 + 51). Memorial Day (May 31) falls after the last day.
