Simi Valley Unified School District in 2026-2027 opens on the earlier side of the school-year cycle on Aug 12, 2026 and runs into the first week of June on Jun 4, 2027. Most families will start with Thanksgiving Break (Nov 23-27, 2026), Winter Break (Dec 21, 2026 - Jan 5, 2027), and Spring Break (Mar 29, 2027 - Apr 5, 2027). Spring Break lands late in the spring recess window.
The practical planning read is that the early start can affect summer camp, childcare, and back-to-school travel timing, the early-June finish keeps the year close to the standard late-spring wrap-up pattern, Thanksgiving is shown as a full-week break, and winter break is one of the longest no-school stretches on the calendar. Those are the dates to check before assuming a normal school week.
The dates outside the big recesses mostly come from standalone no-school days and minimum days. This calendar also calls out district-specific closures such as Classified Holiday. Families should scan the supporting schedule details because they include named schedule items such as Student Holiday and Minimum Day.
CA School Calendar reviews the district's published calendar materials by hand, but the official district calendar page remains the final place to confirm late updates.
The calendar also marks Minimum Day, which can affect pickup timing and after-school plans even when students are still on campus.
The published calendar calls out Classified Holiday in addition to the standard statewide holidays.
For the 2026-2027 school year, Spring Break runs Mar 29, 2027 - Apr 5, 2027 and reaches the end of March.
The first day of school for Simi Valley Unified School District in 2026-2027 is Aug 12, 2026, placing the calendar on the early side of the usual August opening window.
Simi Valley Unified School District ends the 2026-2027 school year on Jun 4, 2027, which places the finish in early June.
