What Is Day and Night?

When events lasts for several hours, we have a new unit of time which is called daytime. You can think of daytime as the time between you wake up until you go to bed.

You can also think of daytime as the time from sunrise to sunset. Daytime is then longer in the summertime than in the winter. Night is the time between sunset and sunrise. Opposite from days, nights lasts longer in the winter.

How long day time and night time is, depends on where in the world you are. Together, a day and a night lasts for 24 hours. Let’s look at some places around the world:

Think About This

If you are North of the Arctic circle, the sun never sets in the middle of summer, and in the winter, it never rises. Imagine waking up in the middle of the night and seeing the sun outside.
