Open Calendar
From webmail, select the Calendar icon in the top bar. The left sidebar lists your calendars. The main area shows a schedule grid.
Views
Switch between day, week, month and list views using the toolbar. Use Today to jump to the current date, and the arrows to move between periods.
Events and tasks
Use the Events and Tasks tabs in the middle column for upcoming items. Add new items with the plus control. Calendar data can also sync to compatible apps via CalDAV — ask support for connection details if needed.
