World Clock — Time Zones
Your own time comes first, followed by the live time in every city you pick.
Your text and files never leave your browser — nothing is sent to a server.
How to use
- The first card shows the time on your device. After it, each city card shows the local time, date and the difference from you.
- Pick a city under “Add a city” and press “Add” to create a card. Use the × on a card to remove it.
- Drag the “Shift time” slider to see what time it will be in every city a few hours from now — handy for planning calls across time zones.
- Your city list is saved in the page address. “Copy link” lets you bookmark it or send it to a colleague.
FAQ
Does it handle daylight saving time?
Yes. Times are calculated from the time zone database built into your browser, so daylight saving changes in the US, Europe, Australia and elsewhere are applied automatically.
What do “ahead” and “behind” mean?
They compare each city with your device’s time. “5 h behind” means the city’s clock reads five hours earlier than yours. Some places differ by 30 or 45 minutes.
My city isn’t in the list. What should I pick?
Choose a nearby city in the same time zone. For example, San Francisco shares Los Angeles time, Boston shares New York time and Osaka shares Tokyo time.
