What timezone am I in?
Detecting your timezone...
About timezone detection
- How does this page detect my timezone?
- Your browser reports your timezone using the JavaScript Intl.DateTimeFormat API. This uses your operating system timezone setting. No geolocation or IP lookup is needed.
- What is an IANA timezone identifier?
- IANA identifiers like America/New_York or Europe/London are the standard timezone names used by computers, phones, and programming languages. They are maintained by the IANA Time Zone Database and updated several times per year.
- Why does my timezone show a city I don't live in?
- IANA timezones are named after the largest city in each zone, not your specific location. If you live in Philadelphia, your timezone is America/New_York because New York is the reference city for the US Eastern timezone.
