Fix problems importing

Import ZIP files

1. Find the ZIP file on your computer.
2. Double-click to open it. You'll see ICAL files (ending in “ics”) for each of your calendars.
3. On your computer, open Google Calendar.
4. In the top right, click Settings   Settings.
5. Open the Calendars tab.
6. Click Import calendars (between the "My calendars" and "Other Calendars" sections).
7. Click Choose File and select one of your ICAL files. You'll need to import each file that ends in “ics” individually.
8. Choose the calendar where you want to add the imported events. By default, events will be imported into your main calendar.
9. Click Import.  Repeat the import steps for each file that ends in “ics.” 

Import CSV or ICAL files

You can also get the "Processed zero events" error if you clicked the Import button more than once. Because the file imported correctly after the first click, the error message pops up on the second click because there weren't any new events to process. Check your calendar to make sure all your events are there.

If this didn't fix your problem, check the formatting of your CSV file or ICAL file.

This error usually happens when Google Calendar can't read some events in your file.

Google Calendar only works with files created by major calendar applications like Microsoft Outlook, Apple Calendar, and Yahoo Calendar. If you exported your file from one of these applications, try exporting it again and re-importing it into Google Calendar.

If this didn't fix your problem, check the formatting of your CSV file or ICAL file.

File size is too large

This usually happens when the file is too big. Google Calendar works with files that are one megabyte (1MB) or smaller.

If your file is too big, export a shorter date range from the original application. You can also separate the file into smaller files if you're comfortable manually editing CSV or ICAL code.

Import started twice

You can also get the "Processed zero events" error if you clicked the Import button more than once. Because the file imported correctly after the first click, the error message pops up on the second click because there weren't any new events to process. Check your calendar to make sure all your events are there.

If this didn't fix your problem, check the formatting of your CSV file or ICAL file.

This usually happens if the file isn't formatted correctly. To fix the format, check the formatting of your CSV file or ICAL file.

First, check your time zone

Check that the time zone in Google Calendar matches the time zone in the original calendar application:

1. On your computer, open Google Calendar.
2. In the top right, click Settings   Settings.
3. In the "Your current time zone" section, select your time zone from the drop-down menu.
4. Scroll to the bottom of the page, then click Save.

You also need to check the time zone settings in the calendar application you exported from. If you need help, check the application's help information.

Next, try importing again

After you've checked your time zone, export your file again and re-import it into Google Calendar.

Some calendar applications will export repeating events as a collection of single events. Because Calendar reads events as the other calendar application exported them, they will import as one-time events.

Check that your file uses a comma as the delimiter

Google Calendar doesn’t work with files that use a semicolon ( ; ) or colon ( : ) to separate fields. Make sure all fields are separated by commas.

Check your file for the correct field headers
