Irvine Unified School District in 2025-2026 starts later than many August-opening districts on Aug 21, 2025 and runs into the first week of June on Jun 4, 2026. The main break blocks to plan around are Thanksgiving Break (Nov 24-28, 2025), Winter Break (Dec 22, 2025 - Jan 2, 2026), and Spring Break (Mar 30, 2026 - Apr 3, 2026). Spring Break is placed near the end of March.
The later start leaves a longer August planning window before classes resume. The early-June finish keeps the year close to the standard late-spring wrap-up pattern. Thanksgiving is shown as a full-week break. Those are the calendar patterns most likely to affect care, travel, and school-site follow-up.
Most of the no-school time is concentrated in the major break windows rather than scattered across the year. Families should scan the supporting schedule details because they include district-specific closure labels such as Admission Day Observed and Spring Recess Observance.
The dates here are hand-reviewed from district calendar materials by CA School Calendar; check the official district calendar page if the district posts a late revision.
