You mean the blue filter on display, which is often referred to as night mode?
Why do computer night lights work?

I have programmed my bathroom light so that it shines fully during the day, at low brightness during the night, and at moderate brightness during 1 hour before and after sunrise and sunset. The time of sunrise and sunset is determined by a rule according to the day of the year.

If you mean automatic brightness correction, most computers have a camera, some have a more generic light sensor.
If you mean night mode, a computer knows what time it is and most know where they are, so they can look up local daylight hours.
If you mean something else, you’ll need to elaborate.
