Time Zone Converter

This time zone converter shows what time it is in other cities for any date and time you choose, with daylight saving applied. Add as many zones as you need and use the planner to find working hours that overlap.

    Each row shows the 24 hours of the selected day in the first time zone. Working hours (9:00 to 17:00) are shaded, and the column of the chosen time is outlined.

    Daylight saving time is applied from your browser's time zone database.

    How to use the Time Zone Converter

    1. Set the Date and time and the zone it is in. It starts with your current time and zone.
    2. Use Add a time zone to add cities. Remove one with its × button.
    3. Read each local time and offset, or use the meeting planner to find hours that suit everyone.

    How it works

    The local time is turned into a single instant in UTC using the rules of its time zone for that date, then shown in each target zone. Offsets come from the IANA time zone database built into your browser, the same data your operating system uses.

    When clocks jump forward, some local times don't exist; when they fall back, some happen twice. The converter tells you when that happens and which offset it used.

    Examples

    • 9:00 in New York on 15 January = 14:00 in London and 23:00 in Tokyo.
    • 12:00 UTC = 15:30 in Tehran (UTC+03:30).
    • 9:00 in Los Angeles in July (PDT, UTC−7) = 16:00 UTC.

    Use city names, not abbreviations

    Abbreviations are ambiguous: CST is Central Standard Time in the US, China Standard Time, and Cuba Standard Time. And "EST" is only correct in winter; in summer New York is on EDT. Picking a city zone such as America/New_York lets the converter apply the right offset for the date, including daylight saving time.

    Limitations

    • Offsets come from your browser. A very recent change in a country's time rules needs an up-to-date browser.
    • Working hours are taken as 9:00 to 17:00 on weekdays.

    Frequently asked questions

    Does the converter handle daylight saving time?

    Yes. The offset for each zone is worked out for the date you pick, so summer and winter times are both correct.

    What does UTC mean?

    Coordinated Universal Time, the reference time zones are measured from. It doesn't change for daylight saving.

    How do I find a good meeting time?

    Add everyone's city and look for a column in the meeting planner where every row is shaded as working hours.
