Timezones
All 418 IANA time zones. UTC offset, DST observance, abbreviations, and the cities each zone covers.
The IANA Time Zone Database — the source of truth for time zone handling on every operating system, programming language, and database — defines 419 canonical zones. Every page below shows the current UTC offset, daylight-saving rules, member cities, and ready-to-paste developer snippets for JavaScript, Python, and Java.
Searching for an abbreviation? Try EST / EDT, PST / PDT, GMT / BST, IST, JST, or AEST. Direct URLs like /timezone/est and /timezone/gmt redirect to the canonical IANA zone.
