If you have previously set up calendar information in another application or web service, you can import the information into Google Calendar.

Google Calendar imports events using the iCalendar or CSV (Comma separated values) file format. If you can export your calendar data into this format, the following instructions will allow you to import the data into Google Calendar:

To import events from iCalendar or CSV files, follow these steps:

1. Click the Add down-arrow button at the bottom of the calendar list on the left side of the page, and select Import Calendar.
2. Click Browse and choose the file that contains your events, then click Open.
3. Select the Google Calendar where you'd like to import events, then click Import.

Please note: recurring events may not be recognized when importing events from CSV files. In this case, individual items will be created for recurring events that fall between the dates you've selected.

If you'd like to migrate your events from another calendar service, there are detailed instructions on how to import these events to Google Calendar from a few other calendar services in the next steps.
