🌍Time Zone Converter

Timezone converter — convert time between cities

Our free timezone converter lets you instantly check the time in London, New York, Tokyo or any other city. Select a source and target timezone, enter the date and time, and the tool immediately shows the converted time along with the hour difference. All calculations account for daylight saving time thanks to the IANA standard and the browser's built-in API.

Current time worldwide — live clock for popular cities

In the Current time worldwide section you will find a live clock showing the current time in dozens of metropolises: from Warsaw and Berlin, through Dubai and Delhi, all the way to Sydney and Tokyo. The clock refreshes every second, so you always see the current time — no need to manually refresh the page.

Frequently asked questions

How do I check the current time in another country?

In the Current time worldwide section you can see live times for dozens of popular cities — the clock updates every second. You can also select any target timezone in the converter and enter the date and time you are interested in.

Does the timezone converter account for daylight saving time?

Yes. Calculations rely on the browser's built-in Intl.DateTimeFormat mechanism with IANA identifiers (e.g. Europe/Warsaw), which automatically handles daylight saving time transitions for each timezone.

How do I calculate the time difference between two cities?

Select the source timezone and enter the date and time. Then select one or more target timezones — the tool will show the converted time and the offset relative to the source timezone (e.g. +2 h or -5 h).

Is my data sent to a server?

No. The converter runs entirely in the browser — no data is sent to any external server. Calculations are performed by JavaScript using the built-in Intl API.
