Public calendar doesn't show on my calendar

If a public calendar doesn't show on your main calendar, the file size may be too large. Google Calendar only works with files that are 1 megabyte (1MB) or smaller. To check if this is the issue:

1. On your computer, open and log into your Google Calendar.
2. On the left, hover over the public calendar.
3. Click More   Settings.
4. Under "Calendar settings," check "Status."
5. If the error message "Could not fetch URL" appears, the public calendar may be too large. For a solution to import existing events only, go to the "Fix problems importing" article. Under the "Formatting errors" section, go to "ICAL file (file ends with 'ics')"  "Check your file size."

Hide someone else's calendar

1. On your computer, open log into your Google Calendar.
2. On the left, under “Other calendars,” uncheck the calendar you want to hide. 

Tip: If you don't want to permanently remove a calendar from your list, you can also unsubscribe from it. To restore access to the calendar, subscribe to the calendar again.
