Daytime starts at sunrise and ends at sunset.
Day length (length of the day) is the time from sunrise to sunset when it is light.
Did you know?
Daylight hours are exactly opposite for the Southern and Northern Hemispheres.
As the UK is a relatively small country the day length does not differ much from place to place.
