That's how many revolutions it takes for the Earth to go around the sun. Each revolution is one day, and it takes 365 of them to complete it's orbit around the Sun. I'm almost sure it was Galileo that figured that out.

It is actually based on how many days it takes the Earth to make one complete orbit around the sun. Since it is a little bit longer that 365 days, every four years we have to add an extra day on the end of February.

Well God or Science depending on who you ask, cause that's how long is takes the earth to rotate around the sun.
