Liberty High School District Calendar 2026-2027 | Printable PDF

If you’re a parent, teacher, or student in Brentwood, Oakley, or the surrounding Contra Costa County area, you need one page bookmarked this year: the Liberty High School District Calendar 26-27. This guide covers every official date for the Liberty Union High School District’s 2026-2027 Instructional Calendar (Modified Traditional Schedule, Version 6), which serves Liberty High School, Freedom High School, Heritage High School, Independence High School, and La Paloma High School.

We verified this directly from Liberty Union High School District’s official calendar PDF, published on the district’s website through Finalsite. Every date below — first day, last day, breaks, testing days, and staff workdays — comes straight from that official document. Nothing here is guessed or copied from an old year’s calendar.

This academic year runs from July 27, 2026 through June 3, 2027, and the district uses an A/B modified traditional schedule rather than a standard five-day week. That means some dates that “look normal” on other district calendars work differently here, which is exactly why so many local families search for the Liberty High School District Calendar 26-27 first day of school and the Liberty High School District Calendar 26-27 printable version every summer.

Parents bookmark this page because school calendars change every year, breaks shift, and one missed memo about a minimum day or a testing date can throw off a whole week of carpools and work schedules.

About Liberty Union High School District

Liberty Union High School District serves grades 9 through 12 in Brentwood, California, and the surrounding Contra Costa County communities of Oakley, Discovery Bay, Byron, Knightsen, and Bethel Island. The district operates five high schools: Liberty High School, Freedom High School, Heritage High School, Independence High School, and La Paloma High School (continuation). Total enrollment sits at roughly 8,200 to 8,250 students district-wide. Denise Rugani serves as superintendent. The district reports a graduation rate near 94% and offers around 29 Advanced Placement courses across its campuses, giving students a solid path toward college-level coursework while still in high school.

What Parents in Contra Costa County Should Know This Year

A few things stand out on this year’s calendar that are worth planning around early.

The school year opens on July 27, 2026, which is noticeably earlier than many neighboring districts that don’t start until mid-to-late August. If you’re used to a late-August start from a previous school or district, mark your calendar now so you don’t miss orientation, sports tryouts, or supply lists.

Fall Break runs a full two weeks, from September 28 through October 9, 2026. That’s longer than a typical single-week fall break, so it’s a real opportunity for a family trip if you plan around it.

Spring Break is also a full two weeks, March 15 through March 26, 2027, plus an additional Spring Recess on April 23 and April 26, 2027. Between those two stretches, spring 2027 has more built-in flexibility than most school years.

Because the district runs an A/B modified traditional schedule, not every school day follows a simple Monday-through-Friday pattern of instruction. Testing days, minimum days, and staff workdays can shift the normal A/B sequence, so it’s worth checking the actual printed calendar for any specific week rather than assuming a pattern.

How Liberty Union High School District Compares to Neighboring Districts

Liberty Union High School District’s late-July start date sets it apart from several nearby Contra Costa County school systems, many of which typically open in mid-to-late August under a traditional calendar. Liberty’s modified traditional A/B schedule is also less common locally, where most neighboring districts run a standard five-day instructional week. Families who have students in more than one district — for example, older kids in Liberty Union High School District and younger siblings in a K-8 feeder district — should expect the start dates, break weeks, and minimum days to not line up exactly, so cross-checking both calendars before booking anything is a smart move.

Planning a Family Trip? Best Times to Travel This Year

If you’re weighing vacation options around the Liberty High School District Calendar spring break 2027 or the fall schedule, here’s how the two longest breaks stack up.

Fall Break, September 28 through October 9, 2026, is a full two weeks and falls right after the summer travel rush, when flights and hotels tend to cost less than peak summer or December pricing.

Spring Break, March 15 through March 26, 2027, is also a full two weeks. Because it lands in mid-to-late March rather than April, it may avoid the more crowded peak spring-break weeks that hit theme parks and beach destinations a few weeks later.

Winter Break, December 21, 2026 through January 1, 2027, is the classic two-week holiday stretch, but expect higher travel prices industry-wide during this window no matter which district you’re in.

School Closings History in Liberty Union High School District

Like most California districts, Liberty Union High School District builds its calendar around 180 required instructional days and generally does not need to add extra snow days, since the area does not typically see winter weather severe enough to close schools. Occasional closures for extreme heat, air quality (wildfire smoke), or other emergencies have occurred in past years across Contra Costa County districts, and any such closure would be announced directly through the district’s official communication channels rather than reflected on the printed calendar in advance.

FAQs

Bottom Line

Bookmark this page now, since school calendars get searched constantly once fall and spring breaks get close. For real-time closings, delays, or last-minute calendar amendments, always check Liberty Union High School District’s official website directly rather than relying on a saved PDF from earlier in the year. If you’re specifically tracking the Liberty High School District Calendar spring break 2027 dates for travel booking, it’s worth checking back in March, since that’s when most families finalize spring plans and when districts occasionally post minor calendar updates.
