Note: Approved by the Aldine ISD Board of Trustees on Jan. 13, 2026; the posted PDF was last updated July 22, 2026. Most campuses follow this traditional calendar; the Additional Days School Year (ADSY) campuses (Ermel, Harris and Vines per the ADSY calendar) follow a separate calendar that starts July 27, 2026 and is not included here. The district calls the Oct. 12-16 and Feb. 8-12 weeks its October and February student holidays (midterm breaks). Oct. 12, Jan. 4-5 and Feb. 8 are staff development days with no school for students; classes resume Jan. 6 after the Midwinter Break. Dec. 18 is a half day for students. The calendar notes that some schools may have calendar adjustments for specific class schedules.
