Time zone converter
Pick a date and time in one zone and read it in another, with daylight saving already accounted for.
Time there—
Difference—
Zones are named the way the IANA time zone database names them, region then city: Europe/Riga, America/New_York, Asia/Kolkata. Start typing either part and pick from the list. The city stands for every place that has kept the same clock rules, so Europe/Berlin covers most of central Europe and America/Chicago the US Central zone.
The conversion uses your browser's own zone rules, so daylight saving is applied on the right dates for both zones, including the days when the difference between two places changes because only one of them has switched. The difference shown is for the moment you picked, not a fixed number.
