World Clock

What it's for

See what time it is in several places at once and find an hour that suits everyone. Each place is a row with the hours of the day lined up, working hours (9 to 5) shaded, and the date shown where a place is already on the next day or still on the day before.

For example, when you’re arranging a call between London, New York and Mumbai, choose the date, then drag across the hours to find a slot inside everyone’s working day.

How to use it

Type a city, a time zone name (Europe/Paris) or an offset (UTC+5:30) into Add a place and press Enter, or pick a suggestion. The first place sets the hours across the top; Make first moves another place there, and your own time zone starts first.

Click an hour to see it in every place, or drag across hours (or Shift-click) for a meeting. With the grid focused, the arrow keys move the chosen hour and Shift with them stretches it. Chosen time in each place gives the times ready to paste into an invitation. Your places and the 12-hour setting are remembered in this browser, and Copy a link to this input keeps the places, date and chosen hours.

Example

Add Mumbai, set the date to 20 October 2026, then click 14:00 in the London row. Chosen time in each place shows:

London: Tue 20 Oct, 14:00–15:00 UTC+1
New York: Tue 20 Oct, 09:00–10:00 UTC−4
Tokyo: Tue 20 Oct, 22:00–23:00 UTC+9
Mumbai: Tue 20 Oct, 18:30–19:30 UTC+5:30

Below the grid, a note says London goes back an hour on Sun 25 Oct and New York on Sun 1 Nov, so the gap between them is four hours for that one week.

Good to know

Daylight saving comes from the time zone database built into your browser, so it works offline and is as up to date as the browser. The city list holds a few hundred large cities and capitals; for anywhere else, type its time zone or offset. An offset such as UTC+2 stays fixed all year, with no daylight saving. When the first place’s clocks change, its day has 23 or 25 hours, and the grid shows them all.
