Changing the time format in Windows 11 feels pretty straightforward — but sometimes it isn’t. Maybe the clock display annoys you, or you’re trying to get your system to match a certain regional format for work or travel. Either way, tweaking whether you see a 12-hour clock (AM/PM) or the 24-hour style can make a real difference in how comfortable you feel when reading the time. This little setup tweak is mostly about personal preference, but it can save a lot of squinting if your screen keeps showing a format you don’t like. Plus, it’s one of those settings that’s easy to toggle later if your mood or needs change.
Changing the Time Format in Windows 11
Method 1: Via Settings Windows
This method is the usual route. It’s simple once you get the hang of it. Basically, you head into the Settings, then dig into Date & Time options. That way, you can switch between 12-hour and 24-hour formats without messing around with registry files or command lines. The whole idea is to make the clock display match your vibe, whether you’re into military time or prefer the classic AM/PM look. Expect the change to be super quick once it’s done – no need to restart or anything complicated. Sometimes, on certain setups, it’s a little picky and may require a quick reboot afterward, but usually, it updates right away.
Step-by-step: How to change the time format manually
- Open the Settings from the Start menu or Windows key + I
- Click on Time & Language.
- Select Language & Region on the sidebar — sometimes the exact menu varies, but it’s basically around there.
- Scroll down to the section called Regional format and click on Change data formats link. If you don’t see that, look for a link that says Change date, time & regional formatting.
- In the drop-down menus under Short time and Long time, pick your preferred style. Usually, you’ll see options like h:mm tt for 12-hour or HH:mm for 24-hour.
- Once chosen, close the Settings. The clock on your taskbar should update instantly.
It’s kinda weird, but sometimes the change doesn’t show up immediately, especially if Windows is hung up or laggy. On some setups, a quick reboot helps. Might as well do it if the clock isn’t updating right away.
Why this helps & When to use it
This quick tweak is perfect if you notice your system clock is in the wrong format for your daily habits or region. For example, if you’re used to 24-hour time, seeing AM/PM all the time might just mess with your head. Or maybe your workplace software expects a certain format for timestamps. Changing it is usually instant, and since it only affects how time looks, your actual clock and scheduling stay intact.
Other tips if this isn’t enough
If the Settings app is being stubborn or you want an even deeper custom look, you could try editing regional formats through the Registry, but that’s kinda overkill for most folks. There are also PowerShell commands, like:
Set-Culture en-GB # for 24-hour formatBut honestly, I wouldn’t mess with that unless you’re comfortable with command line and backing up your registry first. The Settings menu fixes are usually enough, and way safer.
Tips for Changing the Time Format in Windows 11
- Decide if you need to see AM/PM or prefer military time — pick what’s clearer for your life.
- If you’re doing international business or travel a lot, switching to 24-hour might cut down confusion.
- Remember, it only changes the display, not the actual time, so your calendar and alarms stay in sync.
- Sometimes, after changing formats, it helps to log out and back in, or restart, just in case.
- If someone else uses your PC, you can set their preferred format too — it’s user-specific.
Frequently Asked Questions
Can I switch back to the original format later?
Absolutely, it’s super easy. Just head into the same menu and pick the other option. No stress.
Will apps get confused if I change formats?
Mostly no. Most apps default to system settings, but some might display time differently depending on their own preferences. Usually, they’re good at adjusting automatically.
Will this change show on my lock screen too?
Yep. The lock screen clock matches your system format, so it’ll follow whatever you pick here.
What if I want different formats for different users?
That’s fine. Each user can set their preferred format individually — just log into their profile and change the setting as above.
Does switching the time format affect the date?
Not directly. The date format is separate, so if needed, you can change that too in the same menu.

Messing with the Windows time format is surprisingly easy once you get to the right place.
