About the Klein ISD 2026–2027 calendar
Data source
This page is based on Klein ISD's official 2026-2027 English color calendar PDF, the district calendar page, and the district's calendar-approval announcement, checked October 5, 2026. The Board of Trustees approved the calendar November 10, 2025.
How dates are handled
The month grids, written date list, calendar key, grading-period table and school-hours table were checked together. Staff-only dates before the first student day and after the last student day were excluded. Official events remain separate in the event list, while the parent-facing key dates identify adjacent closures that form one continuous no-class period.
Updates
No revision date or weather make-up day appears on the PDF reviewed for this page. Later district announcements can still change attendance dates, so the current Klein ISD calendar page controls.
