Microsoft Teams includes a calendar that shows all scheduled Teams meetings. The Calendar app can be found on the left-hand side of the Teams application.

The Calendar app  can be used to create a instant meeting (Meet now) or schedule a meeting for the future (New meeting). You can also configure the Calendar workspace to view different ranges of dates.

Meetings that are in progress can be accessed through the calendar, as well.

 Note: It will also show any offline meetings that have been scheduled in Outlook.
