Use named zones
Choose places such as London or New York instead of fixed UTC offsets so daylight saving rules stay attached to the conversion.
Time Zone Converter
Follow the current time live or set a specific date and time, then compare it across cities or IANA time zones.
Conversion time
Tip: Make any destination the source, or select a clock to switch between 12 and 24-hour time.
Useful ways to use this tool
Convert the real date
Offsets can change during the year, so set the actual calendar date for flights, meetings, launches and deadlines.
Compare multiple targets
Add more destinations when you need several cities at once, or swap any destination into the source position.
Frequently asked questions
- Why should I select a city instead of GMT plus or minus hours?
- Cities map to named time zones with daylight saving rules, while fixed offsets can be wrong for part of the year.
- Can the converted date be different from the source date?
- Yes. The tool shows the local date for each target so overnight conversions are visible.
