Actually if YOu beleive all of the Relegious Hype, The Bible or waht ever says that God worked 6 days and rested on the 7 th. Right?
Who told God what day it was and is Sat. not the last day of the week? Sunday according to A Calendar is Sunda, the first day of the week.
Heck, I am not a Theologian, just a Human Being!
