@aaronpk VimCal does exactly this! Press "Z" to pop open the timezone selector, type a few characters of the location you want, press enter, boom: your calendar view is shifted to show the new timezone (with the original timezone's times still visible for reference)!
@aaronpk Fantastical allows you override the system timezone and/or to simultaneously display all times in a secondary timezone. (One of the many reasons I use it.)
@aaronpk Apple Calendar actually does this the best, just turn on Time Zone support in Settings and Advanced ... assuming you're on MacOS
@aaronpk on iOS you can use the timezone overwrite
@aaronpk or everyone start using zulu time.
i joke, that's it's own nightmare to coordinate.
@aaronpk and, on mobile without a keyboard, VimCal has a "command center" button at bottom of screen.
Here's a quick screen recording!
Of note:
- Base timezone is EDT
- Creating a new event assumes base timezone, but specific TZ can be set (like with any calendar)
- Using "time travel" updates view to an alternate timezone
- Creating a new event in time travel mode assumes alternate timezone (can override)
- Tap blue banner at top of screen any time to get back to base timezone
