APS Closes for Yom Kippur

Arlington Public Schools lists Monday, September 21, as the Yom Kippur holiday on its approved 2026-27 calendar. Students should not plan for a regular school day on that date, and families should account for the closure when arranging child care, transportation, meals, and other weekday routines. The holiday is part of APS's official school calendar and applies across the district unless a separate school or program notice provides additional information for a particular schedule.
