The exact time anywhere in the world, in real time.
Planning a call abroad, following a market's opening, knowing whether it is too late to call someone: the tool shows the local time in several cities at once. Add as many cities as you need with "+ Add a city" and remove them with one click. The time updates every second.
The tool relies on the IANA time zone database, the one used by operating systems, phones and browsers. It records each region's rules, including the history of clock changes. Switches to and from daylight saving time are therefore taken into account automatically, on the right date for each country.
| Region | Daylight saving time |
|---|---|
| European Union | from the last Sunday of March to the last Sunday of October |
| United States and Canada | from the second Sunday of March to the first Sunday of November |
| Southern hemisphere (Australia, Chile…) | during the northern hemisphere's winter |
| Japan, China, India… | no clock changes |
As a result, for a few weeks in spring and autumn, the gap between London and New York shrinks from 5 hours to 4. That is when most meetings get missed.
Most time zones are offset from Coordinated Universal Time (UTC) by a whole number of hours, but not all: India is at UTC+5:30, Nepal at UTC+5:45, and part of Australia at UTC+9:30. The tool handles these offsets without difficulty.
Yes, the tool uses the official IANA time zones, which automatically handle each country's clock changes on the right date.
No. The times are calculated in your browser from its clock and the IANA database it contains; nothing is transmitted.
It relies on your device's clock, which is usually synchronised automatically. If your clock is wrong, all the times shown will be too.
Coordinated Universal Time, the world reference from which each time zone is defined by an offset, for example UTC+1 for Paris in winter.
