“This change from the luni-solar to a fixed solar calendar occurred in Rome during the repressive measures which were enacted against ALL Jewish customs . . . during the reign of Emperor Hadrian. With the fall of the Nazarene headquarters…at Jerusalem, this new Roman calendar quickly spread throughout ‘Christendom.’ This new calendar not only replaced yearly festival dates such as Passover, but it also revamped the concept of the week and its seventh day.” Iranaeus 2nd Century A.D.
