digitalclock.now — Frequently Asked Questions
Everything about formats, quality, privacy and how Digital Clock works.
General
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.
Digital Clock
Frequently asked questions
Can I change between 12 and 24 hour?
Yes, with the format control under the clock. Your choice is saved in this browser and applies next time you visit.
Are my settings saved?
Yes — format, seconds, colour and size are stored locally in your browser on this device. Nothing is uploaded.
How do I make it bigger?
Use the size slider, or go fullscreen for the largest possible display on your screen.
Does the clock need an internet connection to stay accurate?
It reads your device's clock, which your operating system keeps synchronised. Once the page is loaded it stays accurate on its own.
Fullscreen Clock
Frequently asked questions
How do I exit fullscreen?
Press Escape, or press the fullscreen button again. Your settings are kept either way.
Will the screen stay awake?
In fullscreen the page requests a wake lock where supported, which prevents the display sleeping. It is released when you leave fullscreen.
Is it safe to leave on an OLED screen?
Use a dimmer colour and hide the seconds to reduce burn-in risk, or run it on an LCD panel for long unattended periods.
Clock with Alarm
Frequently asked questions
Will the alarm work if I close the tab?
No. The alarm runs in this page, so the tab must stay open. Minimising the window is fine.
Why did no sound play?
Browsers block audio until you interact with a page. Pressing the set button counts, so an alarm you have set yourself will normally sound.
Can I set more than one alarm?
One at a time on this page. Setting a new alarm replaces the previous one.
Night Mode Clock
Frequently asked questions
Why is a red clock better at night?
Red light is less rich in the short wavelengths associated with suppressing melatonin, and a dim red readout is easier to glance at without fully waking.
Should I hide the seconds at night?
Usually yes. A static display is calmer, and on OLED screens it also reduces the constantly-refreshing area.
Can I use my phone for this?
Yes — open the page, turn the brightness down and keep the phone plugged in, since keeping the screen on overnight uses power.
