More on digitalclock.now

Fullscreen Clock Fullscreen Fill the screen — for a desk monitor, a classroom projector, a lobby display or a stream. Clock with Alarm Alarm A clock and a simple alarm in one tab — set a time and it sounds. Night Mode Clock Night A dim red clock for a dark room — readable at a glance without waking you up.

digitalclock.now is a clock you set up once and leave running. The digital clock takes your format, colour and size and remembers them; fullscreen fills a monitor, projector or lobby screen and keeps it awake; the alarm adds a simple wake-up; and night mode is a dim red bedside display.

Made to be left on

Most online clocks assume you are glancing at them for a second. This one assumes the opposite: that it will sit on a screen for hours. That shapes everything — the wake lock, the dimmable colours, the option to hide seconds, and the saved settings that survive a reload. Our guides cover desktop, classroom, lobby, stream and bedside setups.

Frequently asked questions

Is digitalclock.now free?

Yes — free, no signup, no download, no adverts over the clock.

Can I switch between 12 and 24 hour?

Yes, and the choice is saved in your browser along with the colour, size and whether seconds are shown.

How do I make the clock fullscreen?

Press the fullscreen button under the clock, or open the dedicated fullscreen page which is set up for it.

Will it keep my screen from sleeping?

In fullscreen it requests a screen wake lock where the browser supports it, which keeps a display running unattended.

Does it work offline?

Once the page has loaded it keeps time from your device's own clock, so a dropped connection does not stop it.
