But what if you don't want to make that calendar public? Or what if you want more than read-only permissions? If you're looking to share a calendar privately, the steps required to locate the address are a bit more complicated. You can then use that URL to subscribe to the calendar in question. Copy the given URL (it'll start with webcal).Click on the grayed out 'wireless' icon.
Locating the URL for a Public Calendar is really simple: With a calendar URL, you can use it to subscribe to a calendar in an application outside of the Apple universe (such as with Google or Thunderbird/Lightning). If you're an iCloud user, and you've found a need to share out a calendar to an application via a URL, you've probably come up against a number of hurdles.
