Time Zone Converter
Convert a date and time between any two world time zones.
About this calculator
Scheduling across time zones is where mistakes happen — a call set for '3 PM' means five different things to five people in different cities, and daylight-saving shifts make it worse. This converter takes a date and time in one zone and shows the exact equivalent in another, so you can pin down a single moment everyone agrees on.
It covers major zones across the Americas, Europe, the Middle East, Asia and the Pacific, and it uses your browser's built-in time-zone database rather than fixed offsets. That matters because it means daylight-saving transitions are handled automatically: convert a July time and a January time between the same two cities and you may get different offsets, exactly as you should.
The result shows both the converted clock time and the date at the destination, which catches the easy-to-miss case where a late-evening meeting in one city falls on the next calendar day somewhere else. That single detail prevents a lot of missed international calls.
For counting the days until an event rather than converting a clock time, use the days-until calculator; for measuring elapsed work hours across a shift, use the hours calculator.
Frequently asked questions
Does the converter handle daylight saving time?
Yes. It relies on the browser's IANA time-zone database, so daylight-saving rules for each zone and date are applied automatically rather than using a fixed offset.
Why does the destination date sometimes change?
When the time difference pushes the converted time past midnight, the event falls on a different calendar day at the destination. The converter shows that date so you don't schedule for the wrong day.
Which time zones are supported?
Major zones across the Americas, Europe, the Middle East, Asia and the Pacific are included, covering the cities most used for international meetings.
