About the Time Zone Converter

Coordinating across the globe is hard when everyone's clock reads something different. This converter takes a single moment — a date and a time in one place — and instantly shows the matching local time everywhere you need it. Line up a New York morning against London, Mumbai, Tokyo, and Sydney, and see at a glance who's still asleep and who's mid-afternoon. It's built for scheduling meetings, planning calls, timing launches, catching live streams, and booking travel across regions.

  • Pick the source as the place the event actually happens, then add everyone else.
  • Seasonal daylight saving shifts are applied for the exact date you choose — no manual math.
  • Use “Set to now” to compare the current time around the world in one click.
  • “Copy all times” gives you a clean, shareable summary to paste into a message or invite.

Frequently Asked Questions

Does it handle daylight saving time automatically?
Yes. Each conversion is worked out for the exact date you pick, so daylight saving changes are applied correctly. A time in July and a time in January for the same city can land on different offsets — this tool follows those rules for you, no manual adjusting needed.
What does a time zone offset like UTC+5:30 mean?
It shows how far a place's clock is set ahead of or behind Coordinated Universal Time (UTC), the global reference. UTC+5:30 means the local clock reads five and a half hours ahead of UTC, while UTC-4:00 means four hours behind. Comparing offsets tells you how many hours apart two places are.
How accurate are the converted times?
Very. The tool uses your browser's built-in time zone database — the same standard IANA data that powers phones and operating systems — to place each moment correctly, including historical and seasonal rule changes. It never guesses or hand-calculates offsets.
Which time zone should I pick as the source?
Pick the place where the event actually happens or where the time was originally quoted. For example, if a meeting is set for 9:00 AM New York time, choose New York as the source and the local start time will be shown accurately everywhere else.
Can I add my own city if it isn't listed?
The list covers major cities across every region, and your own location is detected and added automatically. If your exact city isn't shown, choose any place that shares the same time zone — the local time and offset will be identical.
Is any of this sent to a server?
No. Every conversion runs inside your browser using data already on your device. Nothing you enter is uploaded, logged, or shared.
