Complete month-by-month calendar for Antioch Public Schools. Every day is color-coded so you can see school days, holidays, and breaks at a glance.
Antioch Unified School District in 2026-2027 opens on the earlier side of the school-year cycle on Aug 10, 2026 and extends deeper into June than many nearby calendars on Jun 8, 2027. The biggest no-school windows are Thanksgiving Break (Nov 23-27, 2026), Winter Break (Dec 21, 2026 - Jan 8, 2027), and Spring Break (Mar 22-29, 2027). Spring Break comes earlier than the April recess pattern some districts use.
Read as a household calendar, the year mainly means that the early start can affect summer camp, childcare, and back-to-school travel timing, the later June finish can shorten the early-summer planning window, Thanksgiving is shown as a full-week break, and winter break is one of the longest no-school stretches on the calendar. Those points are worth a quick review before families set camp, trip, or pickup plans.
Most of the no-school time is concentrated in the major break windows rather than scattered across the year. The published notes also call out early-release or minimum-day clusters that matter for pickup timing. Beyond the three headline breaks, the details to scan include district-specific closure labels such as Admission Day Observed and Floating Holiday.
CA School Calendar maintains this page from the district's own calendar publications, with the official district calendar page linked for final confirmation.
The student calendar specifically calls out early-release or minimum-day schedules, which can affect pickup timing and after-school plans even when students are still on campus.
The published calendar calls out Admission Day Observed and Floating Holiday in addition to the standard statewide holidays.
For the 2026-2027 school year, Spring Break runs Mar 22-29, 2027 and arrives before the end of March.
The first day of school for Antioch Unified School District in 2026-2027 is Aug 10, 2026, placing the calendar on the early side of the usual August opening window.
Antioch Unified School District ends the 2026-2027 school year on Jun 8, 2027, giving families a later June finish than the usual May-ending pattern.
