- Enter the date and time to convert.

Handles daylight saving automatically
Time-zone offsets change through the year as regions move on and off daylight saving. This converter uses your browser’s built-in time-zone database, so it applies the correct offset for the exact date you enter no need to remember who is on summer time. Enter any date, and both zones are adjusted correctly for you.
Common conversions
Popular pairs people convert include Eastern to Pacific (EST to PST), London to New York (GMT to EST), and India to US (IST to EST). For the Eastern-to-Pacific one specifically, see our dedicated EST to PST converter. For any other pair, just pick the two zones above.
Why use a time zone converter?
Remote work, global teams, international calls, live events and travel all mean juggling different local times. Converting accurately avoids missed meetings and the classic mistake of being an hour off after a daylight-saving change. A live converter that knows the current rules takes the risk out of scheduling across the world.
Time zone converter on any device
The converter runs in any modern browser on Windows, macOS, Android and iPhone with nothing to install. Because it relies on your device’s time-zone database, it stays up to date with daylight-saving rules automatically.
