World Clock
The current time in cities around the world
A live board of cities with their offsets, their daylight-saving state, and a read on whether it is morning, working hours or the middle of the night there.
Questions people ask
The things that come up about world clocks, answered plainly.
Can I add my own cities?
Yes — search any IANA zone and it joins the board. The board is kept in the address bar, so a link to it restores exactly the same set for whoever you send it to.
How many time zones are there?
Thirty-eight distinct UTC offsets are in use, from UTC-12 to UTC+14, and about 350 named zones in the IANA database — because two places sharing an offset today may not have shared one in the past, and history is what the database records.

Time Zone LookupSearch by city, by country or by IANA name, and see what a zone actually does: the time there now, its current and standard offsets, its abbreviation and its next transitions.
Meeting PlannerEvery hour of the next day scored by how many of your cities are inside working hours — so the compromise, when there is no perfect slot, is at least an informed one.
UTC ConverterUTC in, local out, or the other way round — with the offset that applied on that date, which is not always the one that applies today.
