Convert a date and time from one time zone to several others at once. Daylight saving time is applied automatically using your browser's up-to-date IANA time zone database.
How to use the Time Zone Converter
- Pick the date, time and source time zone.
- Add the time zones or cities you want to compare.
- See the converted local times and UTC offsets.
Daylight saving handled automatically
Every IANA time zone (e.g. America/New_York, Europe/London, Asia/Dhaka) includes its full history of DST rules, so conversions are correct for any date — past or future.
Frequently asked questions
What is UTC?
Coordinated Universal Time is the global reference time with no daylight saving; all time zones are expressed as offsets from it.
Why are some offsets 30 or 45 minutes?
Some countries, such as India (UTC+5:30) and Nepal (UTC+5:45), use non-hour offsets.
