importación calendario gmail
You can import calendars using Menu > File > Import > iCalendar. This calendar is not synced with any online calendar.
If you want to subscribe to someone else’s Google Calendar, you can use Menu > Tools > Subscribe to Internet Calendar. You will not be able to edit or add items to that calendar, but you will see when they change anything.
If it is your own calendar, you can add it as an account. Go to Menu > Tools > Accounts and add a new account by clicking the + icon, then choose Calendar.
This is a synced copy of your Google Calendar, so any changes you make will be uploaded to the server.
