Convert time across zones
This time zone converter takes a wall-clock date and time in a source zone and shows the matching moment in a target zone. It covers common world zones including India (Asia/Kolkata), UTC, New York, London, Dubai, Singapore, Tokyo and Sydney.
Daylight saving, handled
Conversions use your browser's built-in time zone database through the Intl API, so
daylight saving transitions are applied automatically for the date you choose — no manual offset
maths required.

What time is entered — source or target?
You enter the wall-clock time as it appears in the source zone, and the tool shows the equivalent moment in the target zone.
Which zones are available?
Around fifteen widely used zones spanning the Americas, Europe, Africa, the Middle East, Asia and Oceania, plus UTC.
Is my data stored?
No. The conversion runs entirely in your browser and nothing is sent to a server.
