Calendar Notes
District context: Harlandale Independent School District serves San Antonio Area 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 Professional Development / Student Holidays (September 21, 2026 - September 22, 2026), Professional Development / Student Holiday (November 2, 2026), Thanksgiving Break (November 23, 2026 - November 27, 2026), and Professional Development / Student Holiday (December 18, 2026). 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), Battle of Flowers (April 23, 2027), and First Student Day (August 12, 2026). Early release or half-day entries to watch include Early Release (October 9, 2026), Early Release (December 17, 2026), and Last Day / Early Release (May 26, 2027). Teacher workdays, planning days, or student holidays are separated from regular school days, including Professional Development / Student Holiday (September 21-22, 2026) and Professional Development / Student Holiday (February 22-23, 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 Harlandale ISD 26/27 Instructional Calendar, updated April 18, 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.
