What Makes a ‘Day’ and How Did We Decide on It?

A day is how long it takes for the Sun to go around the sky and come back. But not everyone used the same way to measure a ‘day’, some people counted on stars or even firelight! A long time ago, humans watched the Sun move across the sky, and that’s where we got the idea of dividing time into days.
