Change Windows Clock to 12 Hour or 24 Hour on Windows 10

Windows 10 displays the time and date on the right side of the taskbar like every other version of Windows previously has. It shows the usual forward slashes between double-digit numbers for the date and a 12-hour format for the time. There’s nothing inherently wrong with that but not everyone likes their time in a 12-hour format. You may have a 24-hour clock in the taskbar but you can always switch back to a 12-hour clock. Windows 10 lets you change between the 24-hour and 12-hour time formats on Windows 10 without any hacks or third-party mods.

Perhaps you want to change the date format, say, you want dashes between the date, month, and year instead of slashes. That’s also possible from the same settings. It’s been a while since Windows 10 was originally launched but the operating system is still a work in progress.

Microsoft has been trying to bring more of the legacy stuff into the modern Windows 10 interface with every update. Fortunately, the Time and date settings have made it there in the latest versions of Windows 10. However, some settings can still be accessed via the legacy interface and Control Panel.

Change 24-Hour Clock to 12-Hour Clock on Windows 10

1. Launch the Windows 10 Settings app and navigate to Time & Language > Region. Alternatively, right-click the date and time in the taskbar and select Adjust date/time. From here, click Region in the left column. 
2. Under the Regional formatting header on the right, select Change data formats.
3. Select your desired date format from the drop-down menu under the Short date. 
4. Similarly, select your desired date and time format from the drop-down menu under the Short time heading. The 24-hour clock formats won’t show AM or PM.
5. Close the Settings app when you’re done.

Additional Date, time & regional settings

While you can change the date and time formats in the Settings app, you can’t add custom formats. To add more uniqueness to the date and time format in your taskbar, you’ll need to access the settings from the Control Panel. To get there, click on Additional date, time & regional settings under the Related settings heading in Settings > Time & Language > Region. This is right below the Change data formats option you clicked on earlier.

1. In the Control Panel, select Change date, time, or numbers formats under Region. 
2. Under the formats tab, click on the Additional settings button.
3. Click the Time tab and under Time formats, you can change to any time format you prefer.
4. Click the Apply button when you’re done. 
5. Similarly, you can change the date format in the Date tab under Date formats.

Done! Having changed the time format to 12-hour from 24-hour or vice versa on Windows 10, do not forget to check our quick tips on swapping the right and left mouse buttons.
