Katy ISD uses a 172-day calendar with many "Campus Professional Learning Days" (students are off, staff works). Most notably, they have a 5-day Fall Break in October, and a "Spring Holiday" on March 26 and 29, right after Spring Break.

Thanksgiving break runs from November 23–27, 2026. Classes resume on November 30. It’s a perfect, full week off to recharge before the winter push. Since the weather is finally cooling down, take the kids to explore the trails at the Katy Prairie Conservancy or enjoy a quiet long weekend at home. It’s a great time to visit family or just relax before the busy December schedule hits.

Winter Break is a two-week stretch from December 21, 2026, through January 1, 2027. Students return on January 5 (since Jan 4 is a staff Campus Day). The weather is chilly, making it perfect for indoor fun. Bundle up and check out the holiday lights at LaCenterra at Cinco Ranch, or visit the Houston Zoo. It’s a magical time in the city, giving kids ample time to decompress after first-semester exams.

Spring Break runs from March 8 through March 12, 2027. Note that students also get March 26 and 29 off for Spring Holidays! The weather in March is usually beautiful. It’s the ideal time for a road trip to the beach in Galveston or exploring local parks. If you're staying in town, check out the Katy Rice Festival or catch a Houston Astros spring training vibe. It provides a major recharge before the final push to May.

Fall Break is a major feature of the Katy calendar, offering a 5-day weekend from October 9 through October 13, 2026. The brutal Texas summer heat has finally broken, making it perfect for outdoor day trips. Head to a local pumpkin patch like Dewberry Farm or visit the Houston Arboretum. It’s a fantastic, well-deserved rest after the intense first quarter of the school year.

Summer break kicks off on May 27, 2027, and runs through mid-August. Because of the intense Texas heat, summer survival means water. Hit the local pools or check out the water parks at Typhoon Texas in Katy. If it's too hot, look for summer camps at the Houston Museum of Natural Science. It's long enough for summer camps, vacations, and plenty of pool time before the new school year begins.

Katy schools are closed on Monday, January 18, 2027, for Martin Luther King Jr. Day. It creates a nice three-day weekend for families. With the mild January weather, it’s a great time to check out the local parks or just relax at home. Many families use this mini-break to volunteer in the community or discuss the importance of the holiday with their kids. Classes resume on Tuesday, January 19.
