I like the way this tool looks, but I am a big fan of the "row-based" designs from these other tools for comparing time zones.

* Every Time Zone: time zone converter, compare time zone difference and find best time for a meeting with one click || https://everytimezone.com/

* Time Converter and World Clock - Conversion at a Glance - Pick best time to schedule conference calls, webinars, online meetings and phone calls. || https://www.worldtimebuddy.com/

And this site has a bunch of great tools for calculating time between days and a bunch of other miscellaneous stuff.
