Digital Clock

What Is an Online Digital Clock?

An online digital clock displays the current time directly in your browser, in large numerals, with no app install and no account required. This one reads your device's clock and timezone automatically, so the time shown always matches your system.

How Do I Use the Online Clock?

Open the page and the time starts running immediately. Click the gear icon in the bottom-right corner to open settings, where you can change the format, colour, and what's shown alongside the time. Hover near the top-right corner for a fullscreen button if you want the clock to take over the whole display. Even when the tab isn't focused, the browser tab icon itself shows the current hours and minutes stacked in two rows, so you can glance at the time from any open tab.

Why Use This Online Clock?

It's fast, free, and stays out of your way: no ads competing with the numbers, no sign-up wall, and no unnecessary motion. Every setting you change is remembered the next time you open the page, so you only have to configure it once.

What Are the Use Cases of a Digital Clock?

A distraction-free clock for a second monitor or spare tablet
A shared display for a classroom, office, or studio
Timing on-air segments, streams, or presentations
A bedside or kitchen display that stays legible from across the room
Checking the time at a glance while screen-sharing

Is the Clock Accurate?

Yes. The clock reads the time directly from your device's system clock once a second, so its accuracy matches your device's own clock. If your computer's time is correct (most sync automatically over the network), the display will be correct too.

FAQ

Does it work on mobile devices?

Yes. The layout scales to any screen size, and settings work the same way on phones and tablets as they do on desktop.

Can I show seconds, switch to 24-hour, or hide the date?

Yes, all from the settings panel: toggle seconds, switch between 12-hour and 24-hour format, and show or hide the date and location independently.

Can I change the color of the browser tab icon?

The tab icon automatically follows whatever display color you pick in settings, so changing the clock's color updates the tab icon too.

Will my customizations persist?

Yes. Your settings are saved in your browser's local storage, so the clock reopens exactly how you left it, even after closing the tab.

Can I change the font, size, or background?

Yes. Settings includes ten digit fonts, a size slider, a bold option, and background swatches with a custom color picker, in addition to the nine preset text colors.

Can I use a photo as the background?

Yes. Open Settings → Background and search Unsplash's photo library right from the panel — pick a result and it becomes the clock's background, with the photographer credited automatically.
