How to use the online clock

Digital or analog, and when to use each
| Style | Good for |
|---|---|
| Digital | Reading the exact time at a glance, from far away or at an angle |
| Analog | A classroom teaching how to tell time, or a calmer look for a waiting room or desk |
12 hour versus 24 hour time
24 hour format removes any AM or PM ambiguity, which is why it is standard on transport schedules, in healthcare and in most of the world outside North America. 12 hour format is more familiar day to day in the US, Canada, the UK and a few other countries.
Switch formats any time. Seconds and the date can be toggled off too, for a cleaner display with just the hour and minute showing.
Where a full-screen clock is useful
- A classroom or waiting room, where Fullscreen makes the time readable from the back of the room.
- A kitchen or workshop tablet propped up where a phone lock screen would otherwise dim.
- A second monitor kept on a simple, glanceable clock while you work on the main screen.
Online clock FAQ
Does the clock use my computer's time?
Yes. It reads the time from your device's own clock, so make sure your device's time and time zone are set correctly.
Can I use this as a classroom or waiting room clock?
Yes, click Fullscreen for a large, clear display that works well on a shared screen or projector.
Does it keep working if my device sleeps?
No, like any web page it pauses when the device sleeps. Keep the screen active for continuous display.
What is the difference between 12 hour and 24 hour format?
12 hour format repeats 1 through 12 twice a day with AM or PM attached. 24 hour format, sometimes called military time in the US, counts straight from 0 to 23, so 3:00 PM shows as 15:00, common on schedules, tickets and in most countries outside North America.
Does the analog second hand move smoothly?
It ticks once each second, like most real analog clocks, rather than sweeping continuously the way some higher-end watches do.
Why would I use this instead of my computer's built-in clock?
The full-screen view is much larger and clearer from across a room than a taskbar or menu bar clock, which makes it better for a shared display, a presentation or a classroom.
