About the Prosper ISD 2026–2027 calendar
Data source
Dates and school hours come from Prosper ISD's official 2026-2027 District Academic Calendar, updated May 26, 2026. The June Board Recap confirms semester-end half-days were added back, and the September Board Recap confirms the October dates.
How dates are handled
Events retain the official date-list boundaries; adjacent student holidays and weekend planning windows are kept separately in breaks. The January 4 and March 12 student holidays are not part of the official Winter Break or Spring Break events. Staff professional-learning dates are included only when students are also off. Normalized grading-period milestone names are derived from official dates. January 5 is an official grading-period start; its semester-start classification is derived from the semester boundary. Bad-weather make-up dates are conditional: countsAsStudentAttendanceDayUnderPublishedSchedule describes only baseline attendance, and mayBecomeAttendanceDay preserves possible activation; conditional dates are excluded from the confirmed no-school list. Compound classifications are queried with getEventTypes or hasEventType. Same-date events are grouped in the page table.
Updates
February 15 and April 26 are conditional bad-weather make-up dates. Prosper ISD announcements control whether students attend on either date, and campuses provide exact early-release dismissal details.
