This page displays a consolidated calendar that contains events from the calendars in all your groups (if the Calendar feature is available in the groups and enabled for group members to use). Buttons and other controls on this page allow you to:

• Show only the events for which you sent RSVPs.
• Display calendar events in Month, Week, Day, or List view. The default is Month view, but if you select another option, that view will be used in your future visits to this page.
• Add an event to any of your group calendars that members are allowed to add events to.
• Subscribe to your Groups.io calendar from another application that supports iCalendar format (such as Google Calendar, Microsoft Outlook, or Apple Calendar).
  Note: The subscription (synchronization) is only one way, from Groups.io to the other calendar.
• Select a different timezone for displaying calendar events.
