What happens in Mavo
One read-only school calendar that rolls forward each year.
Create your free account, name your family home, and add this school calendar. Mavo opens the next school date so you can add who’s handling it. When Irvine Unified School District publishes another school year, it appears in the same linked calendar.
The source controls the schedule, so synced dates stay read-only. You can still add the family details Mavo knows about—who’s handling it, attendance, place, notes, and a clearer title.
One school calendar is included on Free. Everyday includes more school calendars and other outside calendar links.
