If the calendar you want isn't available from within, you can import events from an .ics file to your existing calendar or subscribe to a calendar online and receive automatic updates (known as an ICS subscription or an iCal subscription). You can import calendars from websites or calendar programs that support the .ics file format, such as Apple iCal, Google Calendar, and Mozilla Lightning.

You can search the Internet for lists of iCals, such as those found at Websites for theaters, sports teams, and schools often have an "Add to calendar" link that you can use to download an iCal.

Note:  Microsoft isn't responsible for the accuracy or content of any third-party calendars. We recommend that you review the terms and conditions before importing or subscribing to any third-party calendars.

The difference between importing and subscribing to a calendar

When you import an .ics file, you get a snapshot of the events in the calendar at the time of import. Your calendar doesn't refresh the imported events automatically -- even if the calendar's owner makes an update. This is a good way to add events to your existing calendar that aren't going to change, like tide tables or phases of the moon.

Subscribing to an online calendar connects it to your calendar. Whenever the owner of a calendar you've subscribed to makes changes to the events, updates your calendar. This is a good way to track events that change frequently, like movie times or a school calendar.

Note: This update can take more than 24 hours, although updates should happen approximately every 3 hours.
