How to use it

  1. 1Enter a date and time, and pick the source timezone (or click Now for the current moment).
  2. 2Add any cities you want to compare against.
  3. 3Read each city's local time, date, UTC offset, and time-of-day side by side, then copy the whole list.

Example

9:00 AM in New York is already 2:00 PM in London, 6:30 PM in Mumbai, and 10:00 PM in Tokyo the same day — the list updates instantly as you change the date, time, or source timezone, with a sun/moon icon flagging whether it's morning, afternoon, evening, or night in each place.

How it works

Your chosen date and time is treated as a wall-clock reading in the source timezone, converted to a single point in time, then re-displayed in each target timezone using your browser's built-in timezone database — including daylight saving time, which shifts a few times a year in many regions. The conversion is computed directly from each zone's own offset rather than your device's local timezone, so it stays accurate no matter where you are or which zones you pick.
