I have had to work with people in 3 different countries, 5 cities and various timezones.

If you ever had to interact with people in different timezones, you know how complicated it is to know what time it is for others. If you're like me, you've already made the mistake of booking a meeting with someone at 2am in their timezone...

EveryTimezone.com is a great way to visualize different timezones, but it has its own list of places with their timezones. Luckily they wrote good code and I found a way to customize it to my own needs.

It's simple, just do this:

1. Open EveryTimezone.com
2. Save the page locally (File - Save Page As...)
3. Edit file Time Zones_files/data.js and keep your places
4. Open Time Zones.html

For more details:

• Live customized example
• Customized code

Thanks

Thanks everytimezone team, especially @amyhoy and @thomasfuchs for making this so simple to customize.
