How to use it
Set the date and time in the starting time zone, which defaults to yours. Each row below shows the same moment in another city. Add cities with the box underneath, and remove them with ×. Your city list is remembered in this browser.
A red +1 day or −1 day means the date in that city differs from the starting date.
Common questions
Does it handle daylight saving time?
Yes. It uses the time zone database built into your browser, so the offset shown is the one in effect on the date you picked. That is why the date matters as well as the time.
What can I type as a time zone?
A city name such as Toronto, London or Dubai, or a time zone ID such as America/Toronto. If your city is not listed, pick a major city in the same time zone.
Why is UTC listed?
Coordinated Universal Time is the reference that every other zone is measured from, and it is often used for flights, servers and international meetings.
