Online clock, big and full screen.

The time, big enough to read across a room. Pick a digital, flip or analog face, 12 or 24 hours, seconds and the date. Show your own time or any city, with a second city underneath for a team in another country. Full screen keeps the screen awake, and the mouse hides itself when you stop moving it. Your choices are remembered on this computer.

Press F, or double-click the clock.

Colour

The time comes from your computer's clock, which most computers keep exact over the internet.

The clock runs in your browser. Your settings are kept on this computer only.

Made for a room

Read it from across the room.

01 / Faces

Digital, flip or analog

Big numbers, flip cards that turn each minute, or a classic face with a smooth second hand.

02 / Cities

Any time zone

Every time zone your browser knows, with daylight saving handled, and a second city under the main one.

03 / Full screen

Stays awake

Full screen asks the browser to keep the screen on, and the pointer hides when you stop moving it.

Questions

Good to know.

How exact is this clock?

It shows your computer's clock, which on most computers is kept in sync with time servers over the internet, so it is usually right to well under a second.

Can I show a different city?

Yes. Pick any time zone for the main clock, and a second city to show underneath, for example your office and a client abroad.

Will the screen go to sleep?

In full screen the page asks the browser to keep the screen awake. If your browser does not allow that, change the sleep setting on your computer.

Does it work offline?

Once the page has loaded, yes. It needs no connection to keep time.
