Calendar subscriptions offer a convenient way for you to stay up to date with everything from national holidays to the match fixtures for your favorite sports team. In this article, we'll show you how to subscribe to a public calendar on your iPhone or iPad – all you need in advance is the web address of the calendar (ics) file.
Note that if you want a calendar subscription to sync across all devices signed into your iCloud account, you'll need to subscribe to it on your Mac. To do so, open the Calendar app in macOS and select File -> New Calendar Subscription, enter the URL of the calendar to subscribe to, and then select iCloud in the Location menu.
