Time Zone Converter

It answers “if it is this date and time in my base city, what time and date is it in these other places?” Set your Base city, add compare cities, pick a Conversion date, then set the hour (slider) and minutes. Each row shows that city’s local time, date, and UTC offset for the same instant.

Choose Base city, add one or more cities under Add a city to compare (up to nine besides the base), pick the Conversion date, move the hour slider, and adjust Minutes (0–59). Selected time shows the base wall clock you locked; compare rows update with it. Dragging the hour slider keeps your minutes. Remote rows can be removed with the × button; the base row stays.

Offsets change when a place starts or ends daylight saving time, and the calendar date in another city can differ from yours (for example, still yesterday or already tomorrow). The date picker sets the day for the conversion so those cases stay accurate. Times convert to the minute, including half-hour and 45-minute zone offsets.

Yes. Use the Minutes control (0–59) for times such as 1:09 PM or 14:30. The hour slider sets the hour; minutes stay the same when you drag it.

They only change how times are displayed on the slider scale and in each city row. They do not change the underlying conversion. Use Both if you want 12-hour and 24-hour labels together.

Yes. Each city uses its IANA time zone (for example America/Los_Angeles or Europe/London). For the date you selected, the converter applies that zone’s rules, including DST where it applies, and half-hour or 45-minute offsets when those zones use them.

This page converts a specific date and time (to the minute) across cities. The World Meeting Planner finds overlapping office hours for a group on today’s date. Use the converter for “what time is it there when it is X here?” Use the planner when you need a shared meeting window across several locations.

The links under Popular Time and Zone Conversions open ready-made city or zone pairs (for example common U.S. and international routes). They are shortcuts to those pair pages; the interactive converter above is for any base and compare cities you choose yourself.
