Where these dates come from: dates marked “school” come from Cumnor House School’s own published calendar; we re-check Cumnor House 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 Cumnor House School in October 2026?
Sat 17 Oct 2026 to Sun 1 Nov 2026 inclusive. Pupils at Cumnor House School return on the next school day.
When does Cumnor House School go back to school in 2026/27?
The first day of the 2026/27 academic year is Wed 2 Sep 2026.
Are these the official Cumnor House School term dates?
Yes. Cumnor House School sets its own term dates and publishes them itself, so these come from the school's own calendar rather than from East Sussex 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.
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.
