The method for changing the date format in your system depends on the specific software or application you are using. However, in general, the date format is typically controlled by the regional settings or language settings on your computer or device.

To change the date format to MM-DD-YYYY in Windows 10, you can follow these steps:

Click the Start button and select Settings.

Click on Time & Language.

Select Region from the left-hand menu.

Under the "Regional format data" section, select the drop-down menu for "Short date" and choose the "MM-dd-yyyy" option.

Click on the "Apply" button, and then click "OK" to save the changes.

If you're using a different operating system, the steps may be slightly different, but the general process should be similar. You can also consult the software or application documentation or support resources for specific instructions on how to change the date format.

Keep in mind that changing the date format on your computer or device may affect other applications or programs, so it's essential to test and confirm that the new format works correctly with your system and any other software you use.
