About the timezone converter
Convert wall-clock time between New York (America/New_York) and London (Europe/London). DST is observed automatically for each zone using your browser's IANA tz database, so daylight-savings switches don't require any manual correction.
All 53 supported cities — plus UTC — are in the dropdowns above. Any pair can be deep-linked by adding ?from=X&to=Y to the URL.
