Changing the time format from 24-hour to 12-hour on Windows 10 is a quick and straightforward process. By accessing the Date and Time settings in the Control Panel, anyone can easily make this adjustment in just a few steps.
How to Change Time from 24 to 12 on Windows 10
This section will guide you through the process of changing the time format on your Windows 10 computer from a 24-hour format (military time) to a 12-hour format (AM/PM). Follow these steps to make the adjustment.
Step 1: Open the Control Panel
First, press the Windows key on your keyboard to open the Start menu, then type "Control Panel" and hit Enter.
Opening the Control Panel is the gateway to many system settings, including date and time configurations. This step ensures that you’re in the right place to make the necessary changes.
Step 2: Go to "Clock and Region"
Next, within the Control Panel, locate and click on "Clock and Region."
By navigating to "Clock and Region," you are accessing the specific area where time and date settings are managed. This is where you’ll find the options to change your time format.
Step 3: Select "Region"
Once you’re in the "Clock and Region" section, click on "Region."
Selecting "Region" helps Windows determine how to display various settings based on your locale. Here, you can customize how the time is shown on your system.
Step 4: Click on the "Formats" Tab
In the Region window, go to the "Formats" tab to view different format options.
The "Formats" tab contains all the options for customizing how dates, times, and numbers are displayed on your system. This is where the magic happens.
Step 5: Change the Time Format
Under the "Formats" tab, click on "Additional settings." Then, navigate to the "Time" tab, and change the "Short time" and "Long time" formats to use the 12-hour format (e.g., "h:mm tt" for short time and "hh:mm:ss tt" for long time).
Adjusting these settings will change how the time is displayed on your taskbar and in other applications. Ensure you choose "tt" to include AM/PM in the format.
Step 6: Apply and Save Changes
Finally, hit "Apply," then "OK" to save your new settings.
Applying the changes will update your system’s time display immediately. You should now see the time in a 12-hour format with AM/PM indicators.
After completing these steps, the time on your Windows 10 system will switch from a 24-hour format to a 12-hour format. You’ll notice the change in the taskbar clock and other areas where time is displayed.
