Where these dates come from: dates marked “school” come from St Mary's School Ascot’s own published calendar; we re-check St Mary's School Ascot’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 Mary's School Ascot in October 2026?
Fri 23 Oct 2026 to Sun 8 Nov 2026 inclusive. Pupils at St Mary's School Ascot return on the next school day.
When does St Mary's School Ascot 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 Mary's School Ascot term dates?
Yes. St Mary's School Ascot sets its own term dates and publishes them itself, so these come from the school's own calendar rather than from Windsor and Maidenhead Council — an independent school's terms often differ from the council's by a week or more. Every date is labelled with its source.
Are INSET days included?
Not yet for St Mary's School Ascot. We take INSET days from the school's own published calendar, and this one does not list them separately. Leave the INSET box ticked anyway: this is a live subscription, so once we confirm them they appear in your calendar automatically.
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.
What else can Hermo do for us?
Hermo is a family organiser that does the organising. It reads the school emails directly (no forwarding), pulls trips, dress-up days and payment deadlines into your Google Calendar, and answers questions you’ve told it before (“what size shoe is Mia?”, “where’s the health insurance number?”) so either parent can get the answer in WhatsApp. The weekend watcher looks ahead midweek and flags what’s coming; the half-term watcher surfaces the break weeks early with club and activity options. No new app to install.
Try Hermo →
The dates are the easy part. Covering the holidays is the bit that creeps up. Hermo starts on each school break weeks ahead, with local clubs, prices and times.
