How do I keep a clock on my second monitor?

Open the online clock in a browser, drag the window onto your second monitor, then press the full-screen key so it fills that display. Leave the tab open and the clock runs all day.

How do I stop my clock screen from going dark?

Adjust your device's power or screen-timeout settings to keep the display on, and keep the device plugged in. On phones and tablets, raise the screen-timeout to its maximum while charging.

Can I use an old phone as a desk clock?

Yes. Open the clock in the phone's browser, prop it on a stand, keep it charging, and raise the screen-timeout setting. It makes an excellent always-on clock beside your keyboard.

Does a second-screen clock stay accurate?

Yes. The clock reads your device's network-synced time, so it stays accurate automatically. If the time looks wrong, set the device to update time automatically and check its time zone.

Keep a Clock on a Second Monitor

If you work at a desk with more than one screen, you have a small piece of prime real estate that is easy to overlook: a corner of your second monitor. Parking a clock there means you always know the time without alt-tabbing, reaching for your phone, or losing your place in whatever you are doing. A browser-based clock makes this effortless, and keeping a clock on your second monitor takes only a minute to set up.

This guide walks through exactly how to put a large, always-visible clock on a secondary display or any spare screen, how to stop it from dimming or sleeping, and how to arrange it so it helps rather than distracts. By the end you will have a dependable clock glowing quietly beside your work using our free online clock.

Why Put a Clock on a Second Screen?

A dedicated clock on a spare display sounds like a small thing, but it changes how smoothly your day runs. When the time is always in your peripheral vision, you stop breaking concentration to check it.

Stay aware of time: Glance over and instantly know how long until your next meeting or deadline.
Protect your focus: No need to unlock your phone, which so often leads to a distracting detour.
Pace long sessions: A visible clock helps you keep meetings, study blocks, and work sprints on schedule.
Repurpose spare hardware: An old tablet or laptop propped beside your desk becomes a useful clock instead of gathering dust.

Because the clock reads your device's network-synced time, it stays accurate on its own, and you can choose a digital or analog clock face depending on which you find easier to read at a glance.

How to Keep a Clock on a Second Monitor: Step by Step

The setup is quick and needs no software beyond the browser you already use. Here is the exact sequence for a dual-monitor computer:

Open the clock. On your computer, navigate to the online clock page in a browser tab or window.
Drag it to the second screen. Move the browser window onto your secondary monitor.
Choose your format. Pick a 12-hour or 24-hour display and show or hide seconds to suit your preference.
Go full screen. Press your browser's full-screen key so the clock fills the second monitor with a large, readable time.
Leave it running. Keep the tab open and the clock ticks away all day, requiring no further attention.

That is all it takes. Your main monitor stays completely free for work while the second one shows a big, glanceable clock.

Using a Spare Phone or Tablet Instead

You do not need a true dual-monitor setup to enjoy an always-visible clock. An old phone or tablet works beautifully as a dedicated clock beside your keyboard. Open the clock in its browser, prop the device on a small stand, and keep it plugged in so the battery never runs down. This is one of the best second lives for aging hardware, and the approach is the same one described in our guide on how to use a full-screen online clock.

Stopping the Screen From Dimming or Sleeping

The most common annoyance with a permanent clock is a display that dims or sleeps to save power. Fixing it is simple once you know where to look, and the setting lives on your device rather than in the web page.

On a Computer

Open your operating system's power or battery settings and extend the time before the display turns off, or set it to never sleep while plugged in. Because a desktop clock is most useful on a machine that stays powered, keeping the computer plugged in removes any battery concern.

On a Phone or Tablet

Raise the screen-timeout setting to its maximum, and keep the device charging so it does not dim to preserve battery. Some devices also offer a setting to keep the screen on while charging, which is ideal for a bedside or desk clock. If your screen still dims, lowering the brightness slightly can make an always-on display easier on the eyes during long sessions.

Arranging the Clock So It Helps, Not Distracts

A clock should sit at the edge of your attention, not the center of it. A little thought about placement and format makes it far more useful.

Position it in a corner: Place the clock screen where a quick glance reaches it, ideally just above or beside your main monitor.
Match the format to the task: Use 24-hour time if you coordinate across regions, a topic we cover in 24-hour vs 12-hour clock format.
Hide seconds if they distract: A constantly changing seconds display can pull your eye. Turn it off for a calmer clock.
Dim the brightness: A slightly dimmer second screen is present without being demanding.

Pairing a Clock With Timers and Focus Routines

A visible clock is even more powerful when combined with structured work. Knowing the current time tells you when to start and stop; a countdown tells you how long a block should last. Many people keep a clock on one screen and a timer handy for focus sessions, a combination that underpins the method in our guide on using the Pomodoro technique with an online timer.

The same spare-screen trick works for timers and stopwatches too. During a workout or a long process you might keep a stopwatch running on the second display to track elapsed time. Our broader advice on building a time-aware day lives in using an online clock for time management, which ties the clock into planning and scheduling.

Troubleshooting a Second-Screen Clock

Once set up, a second-monitor clock rarely needs attention, but a few small issues can crop up.

The screen keeps turning off: Adjust your device's power or screen-timeout settings and keep it plugged in.
The clock window moves back to the main screen: Some setups reset window positions after sleep. Reopening and dragging it back takes a moment, or you can keep the window maximized on the second display.
The time is wrong: This reflects your device's clock or time-zone setting, not the page. Set the device to update time automatically, as explained in time zones and UTC explained.

None of these are faults in the clock itself; they are simply a matter of how your display and power settings are configured. Once you have adjusted them, the clock tends to run untouched for days at a time, which is exactly what you want from a piece of your workspace that should fade into the background. If you use several devices, it is worth setting up the same clock on each so that whichever screen you glance at shows the identical, accurate time, keeping your whole desk in perfect agreement.

Conclusion

Keeping a clock on your second monitor is one of those tiny upgrades that quietly improves every working day. Open the page, drag it to the spare screen, go full screen, and adjust your power settings so the display stays lit. Whether you use a true dual-monitor rig or an old tablet propped beside your keyboard, you will always know the time at a glance. Ready to set it up?
