The Ubuntu community is made up of many different teams. All of these teams have their own events. We run different calendars to help keep track of all of the meetings and events that take place in the community. Currently, we have 4 calendars:

The Fridge calendar, which is used to track Ubuntu team meetings/events

The Learning Events (Classroom) calendar, which is used for classroom sessions

The Ubuntu on Air! calendar, used to track video sessions at Ubuntu on Air!.
