# Calendar merge

> Calendar merge is a Marketplace integration for Home Assistant. It has 67 installs sharing analytics, works locally and was last updated April 22, 2026.

Calendar merge combines one or more Home Assistant calendars into a single overview sensor. The overview covers a chosen number of days ahead and is limited to a maximum number of events. Recurring events can be removed from the result, and the sensor can use the event summary as its entity name. Date formatting and a template for the sensor's events can be adjusted, and a switch shows events as time remaining. Repair notices appear in Settings under Repairs when a monitored entity is deleted or renamed, or when a template error occurs. It works locally and is set up in the UI, with the same options available afterwards.
