Timezone converter

Pick a date, a time and two timezones, get the converted local time instantly.

How Timezone converter works

Timezone converter takes a specific date and time in one IANA timezone and tells you the matching wall-clock time in another, "3pm in New York is what time in Tokyo?". It accounts for daylight saving on the exact date you choose, so the result is correct year-round.

If you only need the current gap between two zones rather than converting a specific moment, the Timezone difference tool is more direct. It uses the IANA timezone rules built into the browser, so each conversion reflects whether DST is in effect on the specific date you pick.

Frequently asked questions

How is this different from the Timezone difference tool?

The converter translates a specific date and time from one zone to another, handling DST for that exact date. Timezone difference just reports the current offset gap between two zones, use it when you want the hours apart, not a converted moment.

Does it handle daylight saving time correctly?

Yes. It uses the IANA timezone rules built into your browser, so conversions reflect whether DST is in effect on the specific date you pick, not just a fixed offset.

Is the date I enter sent anywhere?

No. Every value is computed in your browser, on your device. The date you enter never leaves your machine and nothing is stored between visits.

Does it work offline?

Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.

Is it free? Do I need an account?

It is completely free and requires no sign-up. There are no watermarks, no daily limits and no tracking cookies needed to use the tool.
