How to use this calculator
Enter term start and end dates and the date to count remaining days from. Choose instructional weekdays. Add single closure dates or inclusive start..end ranges, then any half-day dates.
Both term endpoints count when instructional. Full days count as one and half-days as 0.5. Closures override half-days, duplicate exceptions count once, and non-school weekdays are not subtracted twice. Monthly totals show equivalents while attendance dates count every full or half-day once. Terms can span up to 731 dates.
A worked example
November 2–30, 2026 contains 21 Monday–Friday dates. Closing November 26–27 and counting November 25 as a half-day leaves 18.5 equivalents on 19 attendance dates.
Is this an official attendance or school-holiday calculator?
No. Supply your actual school calendar. Half-day weighting here is a planning convention and may differ from local attendance-credit rules. School holidays are not downloaded automatically.
