Module Calendar.Julian

Description: This is the Julian calendar, conjured up by the old Romans when their calendar were just too weird. It was used by the christians as so far as the 18th century in some parts of the world. (Especially the protestantic and orthodox parts.)
Note: Don't confuse the julian day with the Julian calendar. The former is just a linear numbering of days, used in the Calendar module as a common unit for absolute time.
