In Windows 11, the date and time formats are defaulted to the regional format you have set during the Windows setup. If you want to change the date format to mm/dd/yyyy, dd/mm/yyyy, or other format you prefer, and time format to 12-hour or 24-hour clock in Windows 11, here’s how to do it.

Generally, you have two choices on how you can change the date and time format.

  • You can change the regional format to any region of your preference which allows Windows and some apps to format automatically dates, times, first day of week and calendar based on the regional format you set.
  • Or, you can manually set each of the formats (date, time, calendar and first day of week) individually based on your preference.
