Irvine Unified School District in 2026-2027 starts later than many August-opening districts on Aug 20, 2026 and runs into the first week of June on Jun 4, 2027. The longest no-school windows highlighted here are Thanksgiving Break (Nov 23-27, 2026), Winter Break (Dec 21, 2026 - Jan 1, 2027), and Spring Break (Mar 29, 2027 - Apr 2, 2027). Spring Break sits in the late-March planning window.
For families comparing calendars, the useful takeaways are that 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, and Thanksgiving is shown as a full-week break. Taken together, those dates can change the best timing for trips, camps, or backup care.
Most of the no-school time is concentrated in the major break windows rather than scattered across the year.
