I think on of the best attempts to fix calendar system was done by George Eastman (Kodak founder), who presented "International Fixed Calendar" created by Moses Cotsworth to League of Nations in 1923. At that time League of Nations was trying to redesign current calendar system and was accepting different proposals.
Unfortunately they failed to come to consensus between different calendar designs :(
