“Six weeks left” sounds comfortable — until you remember that count includes weekends, the inset day, the school trip and the bank holiday. This school term lessons remaining by subject planner turns calendar days into real teaching days and shows, subject by subject, whether your current timetable pace will actually finish the lessons you have left.

How to use the school term lessons remaining by subject planner
Step 1 — Set your term end date. Today is treated as the start, so you only need the last day of term. The planner counts the weekdays in between and converts them into weeks remaining.
Step 2 — Paste your no-school dates, one per line. Inset days, trips, holidays and strike days all count. Lines the tool cannot read are flagged, never dropped silently, and the excluded-dates check shows what was ignored and why.
Step 3 — Add one row per subject. Enter the subject name, its lessons per week and the lessons left to teach, then press “Plan my lessons”. You get the required pace per week, the whole-lesson ceiling, the capacity at your current pace and a shortfall flag for every subject at once.
Worked example with the school term lessons remaining by subject planner
Pressing “Load example” fills in a term ending on 18 December 2026 with three no-school dates: a trip on 13 November, a Saturday (5 December) that falls on a weekend, and an inset day on 7 December. Starting from 31 October 2026, the planner finds 33 remaining teaching days — 6.6 weeks — and excludes 2 of the 3 pasted dates.
The three example subjects are Maths (5 lessons a week, 28 left), English (4 a week, 32 left) and Science (3 a week, 12 left). Here is the per-subject table the tool produces:
| Subject | Lessons left | Required pace / week | Whole lessons / week | Capacity at current pace | Status |
|---|---|---|---|---|---|
| Maths | 28 | 4.2 | 5 | 33 | On track at current pace |
| English | 32 | 4.8 | 5 | 26 | 6 lessons short |
| Science | 12 | 1.8 | 2 | 19 | On track at current pace |
English is the warning here. Four lessons a week for 6.6 weeks gives a capacity of 26 lessons, but 32 are still to teach — so the flag reads “6 lessons short”. Maths and Science are fine at their current pace, which is exactly the kind of split a single “lessons left” number can never show.
Common mistakes this planner prevents
Counting calendar days. “Six weeks left” is 42 calendar days, but once weekends are gone that is at most 30 school days — and often fewer. Planning against 42 days quietly steals a fortnight from every subject.
Running one subject at a time. A single-subject calculator forces you to re-type the same term dates for every subject. With three to five subjects that is five chances to mistype a date, and you still cannot compare subjects side by side. For a different kind of time pressure, the Exam Section Time Planner by Marks splits exam minutes by section weight instead.
Ignoring no-school days. Inset days, trips and holidays are still sitting inside that “weeks left” count. Paste them in once and the planner subtracts every one that falls on a school day — and if your mornings need the same treatment, the Morning Routine Planner works backwards from your start time so you arrive calm.
School term lessons remaining by subject planner FAQs
What counts as a teaching day?
A teaching day is any weekday from today up to and including your term end date, minus any pasted no-school date that falls on a weekday inside that range. Weekends never count, and pasted dates that land on weekends are ignored rather than excluded.
What if a pasted date is a weekend or a duplicate?
The tool never counts it twice and never lets it change the maths. The excluded-dates check tells you exactly how many pasted dates were excluded and how many were ignored, with the reason for each: weekend, duplicate, or out of range (before today or after the term end).
What does “lessons short” mean?
It means your current weekly timetable cannot finish the lessons you have left. Capacity is your lessons per week multiplied by the weeks remaining; if that number is below the lessons left, the flag shows how many lessons short you are. “On track at current pace” means the capacity covers what is left.
What if my lessons left change mid-term?
Just update the “lessons left” figure for that subject and press “Plan my lessons” again. The required pace, whole-lesson ceiling, capacity and shortfall flag recalculate instantly, so you can re-check after every week of teaching.
Does the tool track across terms?
No — it plans one term at a time. Enter the current term’s end date and its no-school days, and when the next term starts, run it again with fresh dates.
