Where these dates come from: dates marked “school” come from St Martin's School’s own published calendar; we re-check St Martin's School’s website about every 3 months for INSET days and any changes, and your calendar updates itself when we find them. Spotted a mistake? Tell us.

Questions parents ask
When is half term at St Martin's School in October 2026?
Mon 19 Oct 2026 to Sun 1 Nov 2026 inclusive. Pupils at St Martin's School return on the next school day.
When does St Martin's School go back to school in 2026/27?
The first day of the 2026/27 academic year is Mon 7 Sep 2026.
Are these the official St Martin's School term dates?
Yes. St Martin's School sets its own term dates and publishes them itself, so these come from the school's own calendar rather than from Hillingdon Council — an independent school's terms often differ from the council's by a week or more. Every date is labelled with its source.
Can I get INSET days too?
Yes, INSET days are in the calendar where we have confirmed them from the school's own published dates, and each one is labelled with its source.
Will the calendar update by itself?
Yes. It is a live subscription, not a one-off copy: your calendar re-checks it automatically, so next year's dates appear without you doing anything, and any correction reaches you the same way. It is free, and you can unsubscribe in one click.
