Switching the time format in Windows 11 from 24-hour to 12-hour isn’t exactly rocket science, but it can feel like a bit of a maze if you’re not used to hunting through menus. Sometimes, the clock just stubbornly sticks to military time, or maybe you’ve switched cities or regions and now the clock looks weird. Making this change can make your PC feel a lot more intuitive, especially if you’re used to seeing AM/PM instead of hours like 14:00. It’s a quick tweak that’s worth doing—it can save some confusion when reading time on your screen or calendar.
How to Change Time Format in Windows 11 from 24 to 12
Method 1: Using the Settings menu (the easiest way)
This method is straightforward, assuming Windows isn’t being uncooperative. It helps because everything’s tucked in the native settings, and it’s usually stable. When you’re tired of the 24-hour clock or just want to see that friendly AM/PM, this is your go-to.
Expect to see the clock switch instantly after these steps, but sometimes, Windows acts weird and needs a reboot for the change to really stick. On some setups, it might take a minute or two for the new format to appear everywhere, including the taskbar clock.
- Open Windows Settings by clicking on the Start menu and choosing Settings or pressing Win + I. It’s like opening the control center for your PC.
- Navigate to “Time & Language” — you can find this in the sidebar or just search for it.
- Select “Date & Time”. Here’s where all the time and regional formatting happens.
- Scroll down to “Additional date, time, & regional settings” — it might seem hidden, but it’s just a couple of clicks away.
- Click on “Change date, time, or number formats”. This is your real playground for adjusting how everything looks.
- In the dropdown under Short time and Long time, select a 12-hour format like `h:mm tt` (for example, 3:45 PM).On some systems, you might see predefined options—pick something that shows AM/PM clearly. If the desired format isn’t listed, you can tweak the “Format” strings directly in the Regional format settings (found under Control Panel > Region > Administrative > Change system locale).This step often confuses folks, but it’s just about customizing the format codes.
Once done, your clock should switch from 14:00 to 2:00 PM pretty fast. If it hangs or doesn’t take effect immediately, a quick restart usually helps — Windows sometimes needs a nudge.
Method 2: Changing via the Registry (more advanced but effective)
This one is kinda sneaky because it involves editing system settings directly. If the menu options refuse to change the format—maybe because of regional settings lock—then diving into the registry might get you there.
Be warned, messing with the registry can break things if you’re not careful. Always back it up first.
- Press Win + R, type `
regedit`, then hit Enter. - Navigate to `HKEY_CURRENT_USER\Control Panel\International`
- Find the key `SShortTime` and `SLongTime`.Change their values to `h:mm tt` for short time and `h:mm:ss tt` for long time. For example, `
h:mm tt` shows 3:45 PM instead of 15:45. - Close the Registry Editor and restart the PC — this forces Windows to read the new settings.
This method is kinda overkill for most folks, but on some machines, it’s the only way to make sure the format changes take hold.
Tips for Changing Time Format in Windows 11 from 24 to 12
- While you’re poking around, check out regional settings—sometimes, regional formats override your preferences.
- Adding an internet clock time sync (via Settings > Time & Language > Synchronize your clock) can keep your time accurate, but it doesn’t affect the format.
- If the clock on your taskbar remains stubborn, try logging out and back in, or a quick restart. Windows can be weird that way.
- Familiarize yourself with both formats—saves some confusion when switching between apps or working with international teams.
Frequently Asked Questions
How do I change back to 24-hour format?
Just reverse the steps — pick a 24-hour format like `HH:mm` in the regional settings or registry.
Will this affect my calendar or alarms?
Nope, only how time shows visually on your screen. Your alarms and calendar entries stay untouched behind the scenes.
Does this work on older Windows versions?
Yup, similar options exist in Windows 10 and earlier, but the menus might be in different places. Windows 11 just made it a bit more streamlined.
What if the settings don’t change immediately?
Try rebooting or signing out and back in. Sometimes Windows needs a little nudge to update all the visual stuff.

Absolutely—same menu, just pick your preferred date style. It’s all linked, but you can tweak each separately.
Summary
- Open Settings > Time & Language > Date & Time.

Wrap-up
Honestly, fiddling with your time format isn’t a huge deal, but it’s kind of satisfying when everything lines up the way you want. Windows can be a little inconsistent about these tweaks, especially if regional settings get in the way, but trial and error usually gets it sorted. Just be prepared to restart or check a few screens if things seem stubborn.
