A large clock on this device
––:––:––

Showing 12-hour time
The large digits are the current time on the device that has this page open. Switch between a digital reading and a face with hands, and between 12-hour and 24-hour time. Dim and the hour format stay in this browser. The page reads the device clock. It does not call a time server.
This device, drawn large
The numbers and the hands both use the clock already set on this computer or phone. This page does not store laps, and it does not count down. Current time in other cities is the city board. A time you type, shown in several cities, is the time zone converter.
Choose the face and the hour style
- Read the large time. Seconds are part of the display, and the date sits under it.
- Choose 12-hour or 24-hour time. That choice is saved in this browser and used the next time you open the page.
- Switch to the face with hands when you want it. Full screen enlarges the clock when the browser allows it. Dim darkens this page only. It does not change the brightness of the device.
What stays on the clock
- A digital reading with seconds and today's date.
- 12-hour and 24-hour time. The 12-hour view shows AM or PM.
- A face with hands that uses the same device time, plus full screen.
A clock you can glance at
- Leave the time and date large on a desk while you work.
- Use the large face in a kitchen or a classroom. When that hour should make a sound, set an alarm at a clock time.
The device clock is the source
- The time is the clock of the device running the browser. A wrong device clock means a wrong page.
- AlarmConfi does not run a time server for this page. It is not an atomic clock and it is not an official time signal.
- A background tab may draw less often. When you come back, the page reads the device clock again. It does not add one second for each missed update.
- Closing the browser stops the drawing. The page does not keep a clock of its own after it is gone.
- A time zone name, when the browser provides one, is the browser's zone setting. It is not your physical location, and this page is not a board of other cities.
Questions about this device clock
Which clock do the large digits use?
They use the current time on the device that has the page open. They are not a time frozen when the page was published.
Can I switch to a face with hands?
Yes. Digital and the face with hands read the same device time. Full screen enlarges whichever face is showing, when the browser allows it.
What is saved for the next visit?
The 12-hour or 24-hour choice, and whether this page is dimmed, stay in this browser. Dim does not change the device brightness.
Does this page sync with a time server?
No. It repeats the device clock. AlarmConfi does not correct that clock and does not present this page as an official time source.
Why would the large time be wrong?
The device clock, its time zone, or its automatic time setting is the usual reason. This page repeats that clock.
How is this different from a board of cities?
This page shows one device. A hidden tab may pause drawing, then read the device time again when it is visible. Other cities, and a time you type, are different pages. Closing the browser stops the drawing here.
