Getting St Mary's School's dates into Cyril
St Mary's School publishes its calendar, and Cyril reads it for you. The term dates, INSET days and the events for your child's year are in your plan from the day you add the school, and they move when the school moves them. Anything else the school sends, forward to Cyril or photograph it, and it joins the same plan, with a reminder before anything needs doing.
These dates are drawn from St Mary's School's published calendar and can change. Always confirm with the school directly before booking travel or holidays. Cyril is not affiliated with St Mary's School; this is an independent listing for parents.
