What happens in Mavo

One read-only school calendar that rolls forward each year.

Mavo checks the link, tells you how many events it found, then asks for a calendar name and color. When Houston ISD 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.

Linked calendars are included with Mavo Everyday and higher.
