About this tool
A timezone converter: enter a date and time in one timezone and instantly see the equivalent time across major world cities. It uses the IANA timezone database (the same one your OS and most languages use), so it accounts for daylight saving time automatically.
For example, if a meeting is at 9:00 AM in New York, the tool shows it as 2:00 PM in London, 3:00 PM in Berlin, 6:30 PM in Mumbai, and 10:00 PM in Tokyo — all adjusted for each city's current UTC offset and DST status.
Useful for scheduling meetings across distributed teams, planning webinar start times, or figuring out when a live event in another country actually starts for you. Quick-jump buttons shift the source time by an hour, day, or week, and a row of live clocks shows the current time in each city.
FAQ
Does it handle daylight saving time? ›
Yes. The tool uses the browser Intl API with the IANA timezone database, which knows each zone DST rules and historical changes. A time that falls inside a DST transition (e.g. when clocks jump forward) is handled per the zone definition.
Why does my city show the wrong time? ›
The timezone list covers major cities across all regions. If your specific city is not listed, pick the closest major city in the same country/timezone — they share the same UTC offset and DST rules. For maximum precision choose the IANA zone (e.g. Europe/Warsaw) rather than a generic UTC offset.
What is the "Now" button for? ›
It sets the source time to the current moment so you can see what time it is right now in every listed city — handy for sanity-checking offsets before scheduling.
