I've been using World Time Buddy for years - https://www.worldtimebuddy.com/

It allows for a calendar view and shows multiple cities together. It's excellent for figuring out a time slot for a team when everyone is living in a different timezone.

Great tool, love the calendar picker to check the DST overlap weeks.

I use also timeanddate.com. It suggests acceptable time slots and can be saved in favs with selected cities, i.e. https://www.timeanddate.com/worldclock/converter.html?iso=20...

I was thinking of this site as well, showing the different time lines and how they offset according to the time difference. Very neat. Just couldn't remember the domain name.

The design is a bit dated as it's not optimized for higher res screens, everything is quite small. I guess people can zoom in.

How do they make money though? I don't see ads or sign up page for extra features. Running this service since 2011, have to pay for hosting fees etc.

There used to be paid options. They sent a notice a couple years ago saying it was going completely free, but with that support has subsided. For example their mobile app is no longer compatible with latest versions of Android.

I bought the app long ago, but now I have a problem: their database isn't updated. Where I live the weekend changed from Fri/Sat to Sat/Sun since a year, but the app seems abandoned.

This is very useful for scheduling, and has a lot of the features being requested.
