Given a subscribed calendar with a url like
https://example.com/example.ics
To force Google Calendar to refresh and reload the contents right now, unsubscribe from the calendar and subscribe to a new calendar with a URL like
https://example.com/example.ics#1
Adding the anchor tag will force Google Calendar to think of it as a new calendar
Many people who come to this gist are not looking for a one time forced refresh but instead to refresh recurringly. If that's you, you should check out @derekantrican 's Google App Script
https://github.com/derekantrican/GAS-ICS-Sync
Which can refresh a calendar automatically every N minutes
Thanks to @rattrayalex for pointing people to this script
@jonas0b1011001 Given that most people who come to this gist are looking for functionality provided by your project ( https://github.com/derekantrican/GAS-ICS-Sync ), not for the trick outlined above about adding an anchor tag to a URL, is there anything you'd like to see me change/update about this gist to try to get those users away from this gist and over to your repo? Maybe I go through and try to delete some old comments in order to simplify this landing page so it's easier for people to find their way to your repo? Any ideas are welcome. I have a contact form linked on my GitHub profile, feel free to use it to email me with any ideas for how to improve this gist.
