How to Switch Your Windows 11 Clock to 24-Hour Time (Military Time) – A Quick Guide

Switching Your Windows 11 Clock to 24-Hour Format

Changing your system clock to display time in the 24-hour format (also known as military time) on Windows 11 is pretty straightforward — and it can be quite handy if you want to avoid mixing up AM and PM. It’s a simple way to keep things clear, whether you’re travelling, working across time zones, or just prefer a tidier display. Once you tweak the settings, your clock will show times like 14:00 instead of 2:00 PM. It might look a bit different, but trust me, it’s just common sense once you get the hang of it.

Steps to Set Your Clock to Military Time

Making the switch to 24-hour time isn’t complicated. It helps avoid confusion that can sometimes come with standard 12-hour formatting. If you’re not sure where to start, no worries — I’ll walk you through the process, so it’s quick and stress-free.

Accessing the Settings

First, press the Windows logo key or tap Windows to open the Start menu. Find the gear icon labelled Settings. That’s your control centre for adjusting all sorts of things on your PC, including your time format. Alternatively, just press Windows + I for a shortcut.

Locating “Time & Language”

In Settings, click on Time & Language in the menu on the left. Here’s where all the time-related options live, making it easy to personalise your clock. To speed things up, you can also just type Time & Language into the search bar at the top.

Adjusting Date and Time Settings

Within Time & Language, select Date & Time. This is where you can set up how your clock and calendar are displayed — like your time zone, daylight saving changes, and display formats. This section gives you all the tools needed to change your clock to 24-hour time.

Accessing Advanced Time Options

Scroll down a bit until you find “Additional Clocks” and click on it. While this mainly allows you to set up multiple time zones — handy if you work with people overseas — it also includes options for custom time display formats. So, if you often need a second clock or prefer specific time formats, this is the spot.

Switching to 24-Hour Format

Back in Date & Time, look for “Change date, time, or number formats”. Click on it to open a new window, probably labelled “Region”. You’ll see drop-down menus for “Short time” and “Long time”. Here’s what you need to do:

  • Set “Short time” to HH:mm for a clean 24-hour display (like 14:00).
  • If you want seconds visible, set “Long time” to HH:mm:ss. Otherwise, leave it as it is.

Click Apply or OK, and your taskbar clock will switch to 24-hour time — job done!

Once you’ve made the switch, it’s a good idea to double-check that your apps and tools play nicely with the new format — especially calendar apps or any time-sensitive software. If you’re not accustomed to reading military time, it might take a bit of getting used to, but there are plenty of cheat sheets online to help. And if you decide the 12-hour clock feels more comfortable later on, you can always revert the settings — just follow the same steps, but choose the standard format this time.

FAQs About Military Time on Windows 11

You’ll recognize military time by the 00–23 hour display, which is pretty straightforward and helps eliminate confusion. Plus, you can set up dual clocks if you’re dealing with multiple time zones — handy for international calls or managing projects across borders.

Here’s a quick guide to add extra clocks:

  1. Press Settings with Windows + I.
  2. Go to Time & Language > Date & Time.
  3. Scroll down and click on “Additional Clocks”, then select “Add clocks for different time zones”.
  4. Choose your desired zones and hit OK.

Don’t worry — changing the clock display format won’t interfere with alarms or scheduled tasks. They’ll work just as usual. If you rely on alarms, just search for the Alarms & Clock app and set them up there.

Wrapping Up: Why Switch to Military Time?

Setting your PC to display time in the 24-hour format can save you from confusion, especially if you’re juggling multiple tasks or time zones. It makes scheduling easier and ensures everyone’s on the same page. Plus, the option to add multiple clocks is a real plus for staying across different regions.

Hopefully, this saves someone a bit of time and hassle. It worked on multiple setups here, so it should be pretty reliable.

Want to switch back to the 12-hour clock? No worries — it’s just a couple of clicks away. This makes it easy to stay organised with your calendar and reminders. Though, be aware: sometimes, switching formats can throw off scheduling apps if they aren’t configured for 24-hour time, leading to a bit of head-scratching about deadlines or meetings.

If you’ve tried the switch and it’s made things messier, you’re definitely not alone. It can take a bit of fiddling to get it right again, but with a bit of patience, you’ll be back to normal in no time.
