About the Aldine ISD 2026–2027 Traditional instructional calendar calendar

Data source

Dates follow the English page of Aldine ISD’s 2026-2027 Instructional Calendar, updated July 22, 2026, and the official Calendar page.

How dates are handled

Student-facing dates are taken from the current English page, including March 26. Employee-only dates outside the student year and summer-program dates are excluded. Holiday ranges remain continuous only where the source supports every intervening school weekday.

Updates

The PDF says some schools may make adjustments for specific class schedules. Later district revisions, weather decisions, and campus announcements can change attendance plans, so the official calendar page is checked for newer files.
