About Time Zone Converter
Choose a date, a time and the zone it is in, then add up to eight target zones to see the local time in each, with its UTC offset, abbreviation, whether daylight saving is active and whether the date shifts. The Meeting planner mode lays the day out hour by hour and shades the working hours so you can see where every city overlaps. Zone rules come from your browser's built-in time zone database, so results follow the rules it ships.
Common uses
- Pick a call time that works for teammates in London, Bengaluru and San Francisco.
- Announce a webinar start time in several regions without three separate lookups.
- Check what a 2 am deployment window is for a team across the date line.
- Convert a flight or event time written in the destination's local time.
Example
Input
2024-07-01 09:00 America/New_York to UTC, Europe/London, Asia/Kolkata, Asia/Tokyo
Result
America/New_York: 2024-07-01 09:00 (UTC-04:00 EDT, DST, source) UTC: 2024-07-01 13:00 (UTC+00:00 UTC, same day) Europe/London: 2024-07-01 14:00 (UTC+01:00 BST, DST, same day) Asia/Kolkata: 2024-07-01 18:30 (UTC+05:30 IST, same day) Asia/Tokyo: 2024-07-01 22:00 (UTC+09:00 JST, same day)
Good to know
- Offsets and daylight saving dates come from your browser's copy of the IANA database, so a very recent rule change may be missing in an old browser. Future dates assume today's rules continue.
- Many zones have no abbreviation in English (the browser reports GMT+5:30 style names), so the abbreviation column shows a dash for those instead of guessing.
- The planner uses whole-hour slots starting at midnight of the chosen date in the source zone, and it does not know about public holidays or individual schedules.
Time Zone Converter FAQ
How do I convert a time from one time zone to another?
Enter the date and time, choose the zone it is in under From time zone, and add the zones you want to compare. Each row shows the matching local time, so there is no need to add or subtract hours by hand.
What happens to a time that falls in a daylight saving gap?
When clocks jump forward, some local times never occur, such as 02:30 on the spring-forward night in New York. The page says so, reads it as the first valid time after the gap, and shows the result for that instant.
Which hour do you use when a time happens twice?
When clocks go back, a local time like 01:30 occurs twice. The page flags it and offers Earlier (still on daylight saving) or Later (standard time), defaulting to the earlier one, because only you know which was meant.
Does the converter handle India and Nepal's unusual offsets?
Yes. India is UTC+05:30 all year and Nepal is UTC+05:45, and the table shows those offsets exactly. Lord Howe Island, which shifts by only 30 minutes for daylight saving, is handled as well.
How does the meeting planner work out the best time?
It lists 24 hours of the chosen day in your source zone and marks each hour as working or not in every selected zone, using the start and end hours you set. Hours that are working in all zones are highlighted and summarised as a range.
Is anything I type sent to a server?
No. Dates, zones and results are worked out in your browser using Intl, and the page stores nothing between visits.
