Complete month-by-month calendar for Corona-Norco Public Schools. Every day is color-coded so you can see school days, holidays, and breaks at a glance.
Corona-Norco Unified School District is a track-sensitive calendar, so this page should be read as the traditional track. On that track, students start Aug 12, 2026 and finish Jun 4, 2027.
The traditional track places most of the major time away from class into three large blocks: Thanksgiving Break on Nov 23-27, 2026, Winter Break on Dec 21, 2026-Jan 8, 2027, and Spring Break on Mar 22, 2027-Apr 2, 2027. The spring recess is long enough that a quick one-week scan will miss part of it.
Corona-Norco publishes school calendars alongside bell schedule information, so this district is one where the calendar page and the school bell schedule page both matter. Use the official district calendar page to confirm the correct track, campus bell schedule, and any late revisions.
Yes. This page summarizes the Corona-Norco Unified School District 2026-2027 school calendar, including first day, last day, spring break, winter break, holidays, printable PDF, iCal, and official source links. The first day is Aug 12, 2026, and the last day is Jun 4, 2027.
No. This page is written for the traditional track. Corona-Norco families should confirm the matching track on the official district calendar page if their school follows a different pattern.
The traditional-track Spring Break runs Mar 22, 2027-Apr 2, 2027, crossing from March into April and lasting longer than a single school week.
Corona-Norco groups calendar and bell schedule resources together. The districtwide no-school dates are only one part of the planning picture; pickup times and bell schedules still need a campus-level check.
Corona-Norco Unified School District ends the 2026-2027 school year on Jun 4, 2027, which places the finish in early June.
Yes. Most of the family-facing no-school time is concentrated in the major break windows rather than scattered across the year.
