World Clock
The live current time and date in major cities on every continent. Each clock updates every second and shows the city's UTC offset — perfect for scheduling calls, flights and events across borders.
How the world clock works, and why it is always right
A world clock is more than a row of numbers; it is a window onto a planet that is always turning. At any given instant the sun is rising somewhere, setting somewhere else, and high overhead in a third place. The clocks on this page capture that by reading the live time in each city from your browser's built-in database of time zones. That database knows each region's offset from Coordinated Universal Time, when daylight saving begins and ends, and even the unusual half-hour and quarter-hour zones used by places like India and Nepal. Because of that, the time you see is the genuine local time, not a rough guess, and it stays correct on the very day a region switches its clocks.
Reading a world clock well
There is a small skill to using a world clock, and it is worth learning. The quickest reliable method is to anchor everything to UTC. Note the moment you care about, find its UTC equivalent, and then translate that single instant outward to each city on your list. This avoids the most common mistake people make, which is assuming the gap between two places never changes. It does change, because countries switch their clocks for daylight saving on different dates, and some do not switch at all. A difference of five hours in winter can quietly shrink to four in summer, which is exactly how meetings end up an hour out.
Why one universal reference matters
Before the railways and the telegraph, every town kept its own time by the sun, and a city to the east would be a few minutes ahead of one to the west. That patchwork became unworkable the moment people could travel and communicate quickly, so the world agreed on a single reference line at Greenwich and a system of broad bands an hour apart. The world clock is the everyday face of that agreement: dozens of local times, all derived from one shared standard, all shown side by side so you can compare them at a glance.
Make it your own
Use the filter box above to jump straight to a city or country. If a place you need is missing, the time-zone converter lets you work between any two of the listed cities, and new locations are added regularly.
