Calendar Notes
District context: Katy Independent School District serves Greater Houston families, where the district calendar is the practical baseline for school-year planning. For 2026-2027, students are scheduled to start on August 12, 2026 and finish on May 26, 2027. The main family planning blocks are Fall Break (October 9, 2026 - October 13, 2026), Thanksgiving Break (November 23, 2026 - November 27, 2026), Winter Break (December 21, 2026 - January 4, 2027), and Spring Break (March 8, 2027 - March 12, 2027). Parents can use this view for travel windows, shared-custody exchanges, childcare coverage, after-school activities, and comparing district days off with work schedules.
What to watch: Notable local calendar items include Spring Break (March 8, 2027 - March 12, 2027). Early release or half-day entries to watch include Early Dismissal (December 18, 2026) and Early Dismissal / Last Day of School (May 26, 2027). Teacher workdays, planning days, or student holidays are separated from regular school days, including Campus Professional Learning Day (No Students) (September 18, 2026), Campus Professional Learning Day (No Students) (October 23, 2026), Campus Professional Learning Day (No Students) (November 2, 2026), and Campus Professional Learning Day (No Students) (February 5, 2027). If bad weather or emergency closures later change the calendar, families should compare this page with the district source before making travel, attendance, or childcare plans.
Official-source handling: Dates are from the Katy ISD 2026-2027 Instructional Calendar, approved January 20, 2026. We manually review first-party district material, screen it for student-facing dates, and organize it into key dates, calendar grids, downloadable files, and printable summaries. Because this page is marked official, families can use it as the main planning view while still checking the district source for late revisions. User-submitted corrections are checked against official district sources before this page is updated.
