We changed from the Julian calendar to the Gregorian calendar because it was out of synch with the solar calendar. The Pope consulted an astronomer and it was decided to add leap years to correct the problems. Catholic countries changed in 1582. However Germany did not until 1700 and Great Britain waited until 1752. Russia did not change until 1918.
