How many lessons do you have left?
Generic school-day counters only tell you how many weekdays remain. Teachers need something different: how many times a specific class still meets after holidays, inset days, and half-terms.
This calculator walks your real timetable — chosen weekdays, period lengths, and excluded ranges — then lists every remaining lesson date so you can pace the curriculum with confidence.
Worked example
You teach Year 9 on Monday and Wednesday for 50 minutes until 12 June. After adding spring half-term and two inset days, the tool might show 18 lessons left across 9 teaching weeks (15 hours). Export the dates as CSV or a calendar file, or open GapFiller to turn them into a living plan.
Results always depend on your school calendar — add every closed day your class does not meet.
