Time Zone Converter

Convert any time between any two time zones.

Scheduling across continents means doing mental math with daylight saving changes. Pick a date and time, choose the from and to time zones, and get the exact converted time, including the UTC offset each zone is using on that date. The converter uses your browser's built-in time zone database, so daylight saving is handled correctly. Plan meetings without the 3 a.m. surprise.

About Time Zone Converter

A 2 p.m. meeting in New York is 7 p.m. in London in winter and 8 p.m. in summer, and getting it wrong means someone joins at 3 a.m. Daylight saving rules differ by country and change over the years, so mental math is unreliable. This converter does the lookup properly.

It uses the time zone database built into your browser, the same data operating systems use, so offsets and daylight saving transitions are correct for the exact date you pick. The result shows the converted time plus the UTC offset each zone is using on that date, so you can sanity-check it.

Pick the date first, then the time, then the zones. If you schedule recurring meetings, re-check after daylight saving changes, since the offset between two zones can shift by an hour.
