    When clocks repeat an hour

    Convert time zones for a specific date

    Compare a local time in up to eight locations using server-side IANA time-zone rules. Search cities worldwide, or add UTC and IANA identifiers directly. A date is required because a city’s offset can change during the year.

    We flag nonexistent times when clocks move forward and ask you to choose an occurrence when clocks move backward. Choose a city instead of ambiguous abbreviations such as CST or IST.

    Dates supported: 2000–2100. Time-zone rules are checked weekly; future rules can change. All calculations use our server’s time-zone database, not the version installed in your browser.
