Corona-Norco Unified School District in 2025-2026 opens on the earlier side of the school-year cycle on Aug 11, 2025 and runs into the first week of June on Jun 4, 2026. The biggest no-school windows are Thanksgiving Break (Nov 24-28, 2025), Winter Break (Dec 22, 2025 - Jan 2, 2026), and Spring Break (Apr 13-17, 2026). Spring Break is one of the later spring recesses in this group.
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 early-June finish keeps the year close to the standard late-spring wrap-up pattern, and Thanksgiving is shown as a full-week break. It is worth checking these points before locking in camps, travel, or pickup plans.
Most of the no-school time is concentrated in the major break windows rather than scattered across the year.
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.
