Time Zone Challenge

It's 9 in the morning in Nashville: what time is it in Dubai? 10 pairs of busy airports.

How to play Time Zone Challenge

Each round gives the local time at one airport and asks for the time at another. The offsets are today's, summer time included, so the answer can change through the year. Some zones are 30 or 45 minutes off the hour, and some answers fall on the next or the previous day.

Ten pairs per game from the 150 busiest airports. After each answer you see both UTC offsets and the time difference.

Tips

  • Work from UTC: subtract one offset and add the other.
  • India is UTC+5:30 all year; much of Europe and North America shift by an hour for summer, on different dates.

Where the data comes from

Time zones from timezone-boundary-builder (data © OpenStreetMap contributors, ODbL); today's offsets from your browser.
