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: Marked 'Approved 02-03-2026'. Spring break is listed as Mar 22-25 and Mar 29; Mar 26 is a separate 'Holiday - All Schools and Offices Closed', so students are off Mar 22-26, and Mar 29 is off unless needed as a make-up day. Possible make-up days: Jan 29, Feb 15, Mar 29. Three inclement weather days are built into the end of the year (last day June 16 includes them). June 15 and 16 are two-hour early dismissals; June 15 is the last day for Pre-K students, June 16 for K-12. Juneteenth (June 18) falls after the last day. The document states a minimum of 180 student days but no total, so instructional_days is 0. Marking periods and semesters total 183 days per the document.
