If you really want to dig into previous calendards, you will realize that it 
is actually very difficult.

Here are a few of the ways different European countries changed from 'old' 
Julian Calendar to 'new' Gregorian Calendar:

Denmark: 11 days omitted in February 1700.
Sweden: Gradual change over 40 years (February 1712 had 30 days!).
England: 11 days omitted in September 1752.
Germany, Holland and others: Different for Catholics and protestants.
