  1. Right-click on the time displayed on your taskbar and select “Adjust date/time.”
  2. In the Date & time settings window, ensure that the date, time, and time zone are set correctly for your location.

To turn on Location services, follow these steps:

  3. In the left panel of the Privacy settings, select “Location”.

Once you have enabled Location services, try using the Night Light feature again and see if it functions properly with the automatic schedule based on sunset and sunrise.


Summary:

To ensure that Night Light can accurately schedule its activation based on sunset and sunrise, you need to have Location services enabled on your PC. By allowing your device to access your location, Night Light can determine the local sunset and sunrise times, allowing for a more seamless and automatic adjustment of your display’s color temperature.

Here are the steps to turn on Location services:

  1. Open the Windows Settings by pressing the Windows logo key and I together.
