Calendar Notes
District context: Southside 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 Fall Break (October 8, 2026 - October 12, 2026), Thanksgiving Break (November 23, 2026 - November 27, 2026), Winter Break (December 18, 2026 - January 5, 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) and Battle of Flowers (April 23, 2027). No recurring early-release entry is listed in the student-facing data used for this page. Teacher workdays, planning days, or student holidays are separated from regular school days, including Student Holiday - Staff Development (February 12, 2027). Bad-weather, inclement-weather, or makeup-day language is preserved when the district publishes it, which matters for childcare, transportation, and travel planning.
Official-source handling: Dates are from the Southside ISD Academic Calendar 2026-2027, board approved February 11, 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.
