Why Does a Week Have Seven Days? (Encore)
Everything Everywhere Daily: History, Science, Geography & More
Most of our major divisions of time are based on some sort of natural event.
A year is one orbit of the Earth around the sun.
A month is one orbit of the Moon around the Earth.
A day is one rotation of the Earth about its axis.
However, one of the most commonly used units of time has no natural analog whatsoever.
Learn more about why there are seven days in a week and where the names for the day of the week come from on this episode of Everything Everywhere Daily.
