The Calendar Tab allows you to view and create calendar events. The calendar allows you to set recurring events and reminders for any given event. It is easy to set up multiple calendars and share them between multiple users. You also have the ability to invite participants for an event, and check their availability. The calendar supports import and export of popular calendar formats, and you can even synchronize your calendar to your mobile devices using SyncML, ActiveSync, or CalDAV synchronization technologies.
