Calendar
The calendar shows the group's events and the members' birthdays. You can also add simple activities with a start and end date.
All events and birthdays are shown automatically in the calendar.
Add calendar activity
If you want a more "simple" activity in the calendar, you can create it directly from this page. These will NOT be shown under Events, because they are not real events.
Choose a category, choose start and end date (note that times CANNOT be selected), enter the title and description, and click "Add activity".
