When you are working on user research that involves people from all over the world, as I am right now, scheduling means you need to know your time zones.

To help with that, I turn to the Meeting Planner page at time and date.com.

Pick a date, enter your own location, and then pick up to four cities in the world, and you get a timetable showing what time it is for everyone you want to contact.

But what if all you have as a phone number? How do you know what country that phone number is in?

Aha! If the phone number begins with the country code (which means you need to remember to ask people to give you that), then you can find out which country using this. Reverse look up for country code 255 That is how I found out this participant is in Tanzania.

Put to two together, and I am going to be conducting a remote usability session at 5 am Pacific Standard Time with a dude in Tanzania who is about ready to go home for the day.
