Montebello Unified School District in 2026-2027 starts in the middle of the usual late-summer range on Aug 17, 2026 and extends deeper into June than many nearby calendars on Jun 11, 2027. The longest no-school windows highlighted here are Thanksgiving Break (Nov 23-27, 2026), Winter Recess (Dec 21, 2026 - Jan 11, 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 mid-August opening fits the common California back-to-school window, the later June finish can shorten the early-summer planning window, Thanksgiving is shown as a full-week break, and winter break is one of the longest no-school stretches on the calendar. Taken together, those dates can change the best timing for trips, camps, or backup care.
Outside those major breaks, there is one extra standalone no-school day to keep on the family calendar. This calendar also calls out district-specific closures such as Local Board Holiday. Families should scan the supporting schedule details because they include named schedule items such as Student Holiday.
The calendar dates on this page are checked against district-published materials; families should still verify late changes against the official district calendar page.
The published calendar calls out Local Board Holiday in addition to the standard statewide holidays.
