World Clock
Keep live clocks for the places you work with. Each one shows the local time and date, how far ahead or behind it is and whether it's day or night.
CLOCKS
Day means 06:00 to 18:00 local time, not actual sunrise and sunset. Your list is remembered in this browser.

How to use the world clock
Add cities
Search for a city, region or offset. Your own time zone, UTC and a few major cities are there to start with.
Arrange the list
Move clocks up or down and remove the ones you don't need. Switch between a 12-hour and a 24-hour clock.
Come back later
Your list is remembered in this browser, so the same clocks are there next time.
Ahead, behind and the date line
Each clock shows how many hours it is ahead of or behind your own time zone, and tomorrow or yesterday when the date is different. Offsets follow daylight saving, so the difference to a city can change during the year.
Day or night
The sun or moon shows whether it's between 06:00 and 18:00 local time. It's a quick hint before you call someone, not the actual time of sunrise or sunset.
Frequently asked questions
Where is my list stored?
In your browser's storage on this device. It's never sent anywhere, and clearing your browser data removes it.
Why isn't my city in the list?
Time zones are named after one city in each region, such as Europe/Berlin for Germany. Pick the zone of a nearby city that keeps the same time, or search for your offset.
How accurate are the clocks?
They use your device's clock. If its time is wrong, the clocks are too; most devices set their time automatically.
