- On the page with the embedded calendar you want the ical feed for, you use browser tools to inspect the page. Find the iframe element for the calenar and look for the src property:
the src address in an embed link - either email or calendar group account ([email protected]) - is part of the ical url
https://calendar.google.com/calendar/embed?src=**[email protected]**
to
https://calendar.google.com/calendar/ical/**[email protected]**/public/basic.ics
- Paste the ical feed into whatever reader/other app than Google that you use for calendaring :)
