Time Zone Converter
Convert a date and time between two cities or time zones with daylight-saving changes handled correctly.
About this tool
This free time zone converter tells you what time it will be in another city for a given date and time. Use it to schedule a meeting with a client in New York, call a supplier in Shanghai, follow a live event or plan a trip. The time difference is shown alongside the result, for example +6 h.
The tool offers 21 cities and time zones, including UTC, Paris, London, New York, Los Angeles, Tokyo, Dubai and Sydney, and adds your own time zone automatically if it is missing. Daylight saving time is applied for the date you choose, using your browser’s time zone data. If the time you enter is skipped or occurs twice when clocks change, a message explains it.

Frequently asked questions
Does it handle daylight saving time?
Yes. The offset is calculated for the date you enter, using each zone’s daylight saving rules. If the time falls on a clock change, the tool says so and explains which time it uses.
My city is not in the list. What can I do?
Choose a city from the list that is in the same time zone. Your own time zone, detected by your browser, is added automatically if it is not among the 21 offered.
Is my data sent to a server?
No. The conversion is calculated by your browser, and the date and time zones you choose are not sent anywhere.
Is the time zone converter free?
Yes, it is free with no sign-up or account.
