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: Teacher workdays are the dates the calendar marks 'Staff Only' between the first and last day of school. Other staff-only days fall before the first day or after the last day. Early release days are shaded on the grid, and May 20, the last day, is also an early release day. Campus bell schedules: ECC 8:30-4:05, Elementary 8:20-3:55, Middle and High 7:25-3:05. Memorial Day (May 31) and Juneteenth (June 19) fall after the last day of school. The calendar does not say it was board-approved, so status is unknown. The 170 instructional days is the sum of the printed semester totals (84 + 86).
