List of acceptable Google Calendar api time zones - google-calendar-api

Question

I'm working with Google's Calendar API, and I'm running into a bit of an issue. When I set the dateTime of an event I insert, I'm required to set the hour offset, but because o DST, it's off an hour. There is a property I can set for the calendar to set the timezone by name, which I would think would fix my problem, because Google would figure out the correct hour offset. However I do not know all of them, nor can I find a place that lists them. For example "America/Los_Angeles" or "Europe/Zurich". Anybody know where I can find them?

Answer 1

I think I have found the list that I was looking for on this website:
http://www.timezoneconverter.com/
Here is what I ended up needing:
America/New_York
America/Chicago
America/Denver
America/Los_Angeles
Specifically it was on this page

Answer 4

For modern browsers, you can get a list of available time zones with a single line of code:
Intl.supportedValuesOf('timeZone')
If you want the official list of values used by Google Calendar, check out the Time Zone Database, as provided in the reference.
