Time Zone Converter
Convert a date and time between time zones and see the UTC offset for each, making cross-time-zone scheduling painless.
About Time Zone Converter
A time zone converter solves the scheduling problem that comes with any distributed team or international plan: figuring out what 9am here means over there. Time zones, UTC offsets, and daylight saving shifts make mental math unreliable, and a wrong conversion can mean missed meetings and annoyed colleagues. This tool converts a specific date and time between two zones and shows each zone's UTC offset for confirmation.
Conversions use the IANA time zone database built into the browser, the same data that powers operating systems and scheduling software. That means daylight saving transitions are applied automatically and correctly for the exact date you choose, not just the current season. You can pick any recognized zone, such as London, New York, Tokyo, or Sydney, and because offsets are shown alongside the result, you can verify the logic yourself rather than trusting a black box.
Remote teams coordinate standups and deadlines across zones every day, and recruiters scheduling interviews with candidates in other countries rely on it to avoid double-booking. Travelers confirming flight arrival times and event planners advertising a global webinar start time across regions also benefit. Anyone who has ever opened a calendar full of ambiguous times will appreciate seeing both zones' offsets spelled out.
How to Use
- Pick the date and time you want to convert.
- Select the source time zone and the target time zone.
- See the converted time instantly, along with both UTC offsets.
Example
09:00 New York (UTC-5) to London (UTC+0) 14:00 London
New York is five hours behind UTC during standard time, so 9:00 in New York is 14:00 in London.
FAQ
Does this account for daylight saving time?
Yes. Conversions use the browser's up-to-date time zone database, so DST is applied correctly for the chosen date.
Which time zones are available?
All IANA time zones recognized by the browser, including major cities like London, Tokyo, Sydney, and New York.
Can I convert between more than two zones?
This tool converts between two zones at a time. It's the fastest way to confirm a specific meeting time across one pair of locations.
What is a UTC offset?
It is how far a zone sits from Coordinated Universal Time, such as UTC+5:30 for India. Knowing both offsets lets you compute the difference between two zones directly.
Why does the same city show different offsets at different times?
Because of daylight saving time. Zones that observe it shift by an hour in spring and fall, which is exactly why date-aware conversion is essential.
