World Clock & Time Zone Converter

Convert a time between any two zones (DST handled automatically) and keep a live clock for the cities you care about. Search a picker by city, zone, phone code, or US/Canada area code (e.g. +44, or 201 for New Jersey).

Powered by your browser's built-in IANA time-zone database (the same one your OS uses) — DST rules stay current automatically, nothing is hardcoded. Phone- and area-code search use small built-in lists (area codes cover major US/Canada metros).
