This website can generate a link of a google calendar that always displays in the viewer's local time. This was made for the purpose of online events.
Just copy and paste the src attribute from the embed link after a ? after the url like this:
?src=your_calendar@group.calendar.google.com
So the final link would be like this:
https://calendar.gozarproductions.com/?src=your_calendar@group.calendar.google.com
You can find the website at https://calendar.gozarproductions.com
