Online Clock
The current time from your device, large and readable. Go full screen for a desk, classroom or exam-hall clock, switch between digital and analog, and pick a theme that suits the room.
How to use it
- The clock starts as soon as the page loads; it shows your device’s local time.
- Use the switches to show or hide seconds and the date, and to choose 12-hour or 24-hour time.
- Turn on Analog for a clock face with hands.
- Pick a theme, then press the full-screen button (or F).
Where the time comes from
The clock reads the time from your device, in the time zone your device is set to. Phones and computers normally keep their clocks synchronized over the internet, so it is usually right to well under a second — but if your device’s clock is wrong, this clock will be wrong in the same way.
To see the time somewhere else, use the world clock.
Questions people ask
Can I leave it on all day?
Yes. With “Keep screen on” switched on, the page asks your device not to dim or lock while the clock is showing. Some devices ignore this in battery-saver mode.
How do I switch to 24-hour time?
Use the 24-hour switch. The choice is remembered and used across the site, including “ends at” times on timers.
Is this an atomic clock?
No. It shows your device’s clock. Devices set to update their time automatically are typically accurate to a fraction of a second.
