How it works
Each city card displays the live time using its IANA time zone, such as Europe/London, so daylight saving time is applied automatically without a manual offset.

Interactive calculator
This calculator becomes interactive when JavaScript is available. The page still provides its method, limits and related tools without JavaScript.
Result classification
Standard-based. The result follows a published technical standard or the browser’s IANA time-zone data. Browser time-zone data can vary by version, so important historical or future rules should be confirmed.
Limitations
Depends on the browser’s standards and time-zone database version. Repeated or nonexistent local times require an explicit choice.
