It would be fairer to blame the Protestants. The Gregorian calendar was introduced by Pope Gregory XIII (a Catholic) and it stole ten days off those countries that adopted it early. October 5th 1582 became October 15th 1582. They only did this so they could figure out when to have Easter Sunday. Religious nutters.
Hey don't be blaming us prods but thanks for putting in brackets that the pope is catholic. Who'd of thunk it?
As a card carrying atheist, I view all religious nutters as being equally stupid. Protestant, Catholic, Anglican, Methodist, Baptist, Lutheran – take you pick, all wasting their time grovelling to their non existent deities.
