Who created the leap year?

Answer 1

An excellent question in that there was no single person that created leap years.

Throughout the history of civilization many cultures all over the globe created calendars. Most were initially based on the phases of the moon. It was soon discovered, however, that these did not coincide with the length of the years exactly. Slowly, over a period of time, the moons phases fall out of synchronisation.

These cultures, which included the Mayans, Egyptians, Chinese and many others took it upon themselves to calculate just how many days were in a year. Many came to the conclusion that there were approximately 365.25 days in a year. This was remarkably accurate considering the limited technology available at the time.

Some also realised that adding one extra day every four years would tend to correct the error somewhat, though not completely.

The leap year as we know it comes from the Roman calendar which was modified by Julius Caesar (the Julian calendar) and later by Pope Gregory XIII, the Gregorian calendar which is the one much of the world uses today.

Answer 2

The leap year wasn't started by anyone. As scientists worked out all they know about the solar system they realised that the Earth takes 365 and a quater days to orbit the Sun. Therefore every four years there is an extra day made up = a leap year.

Answer 3

Julius Caesar invented the leap year over 2,000 years ago.

Answer 4

Julius Caesar created the concept of the leap year, although it has changed slightly to fit the Gregorian calendar. Leap year is every four years and years that are divisible by four.

Answer 5

Julius Seacer in 45 BC and Pope Gregory in 1583 would be the suitable answer.

Answer 6

Scientists who studied the earths rotation, 365 and one fourth days, they take away the one fourth for four years and then add an extra day because of the 4/4.

Answer 7

Leap year was started by the Romans
