How to Change Your Computer's Date and Time Using Command Prompt

Turn off automatic date and time

Understand why this step is necessary. Although you can change the date and time on your computer using Command Prompt while automatic date and time are active, the computer will eventually reset the date and time to match the current date and time.

In some cases, the computer will automatically reset the time and date as soon as you close the Command Prompt.

Open Start . Click the Windows logo in the lower left corner of the screen.

Open Settings. Click the gear icon in the lower left corner of the Start window. The Settings window will appear.

Click Time & Language . This option is in the middle of the Settings window.

Click Date & time . This tab is located in the upper left of the window.

Click the blue "Set time automatically" switch. The switch will turn gray, so Windows will no longer automatically set the date and time. At this point, you can freely change your computer's date and time in Command Prompt.

The date format you need to use in Command Prompt will depend on the country, but Command Prompt will display the format: type dateand press ↵ Enter, then enter the date you want to use in the format specified by Command Prompt ( for example: "dd-mm-yyyy" in Vietnam) and press ↵ Enter.
