The School Term Duration Calculator makes it easy to plan academic terms by computing total calendar days, full weeks, and actual school days within a term. Enter a start and end date — or supply a number of school days to calculate the corresponding end date — and the tool will optionally exclude weekends and user-specified holiday dates for accurate school-day counts. This is ideal for school administrators and teachers planning timetables, exam schedules, or term calendars. The lightweight, mobile-friendly HTML can be saved as a standalone page or embedded into any WordPress site using a Custom HTML block.
