Sometimes a Google Calendar you subscribe to on the web doesn't automatically show up in your phone or computer’s default calendar app and there’s one extra step you have to take for it to show up in any non-Google calendar app.
You must already have your Google account set up in your phone's settings if you’re using the default mail app. Look for the 'Accounts' section to add it and make sure syncing calendars is turned on.
Log in to your Google account at https://calendar.google.com/calendar/iphoneselect and you’ll see a list of all your personal and shared calendars.
Check off which calendars you want to sync. Shared calendars need to be selected individually, as the default setting is 'off'. Don't forget to hit save when you're done.
It may take a few minutes for your app to refresh, you can try restarting your phone to force one.
