The Old Testament, a sacred book to both Christians and Jews, says, in Exodus 8:11, prohibits working on Sunday (the "sabbath.") "Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is a sabbath to the Lord your God. On it you shall not do any work, neither you, nor your son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy." The "blue laws" enacted this into civil law. As recently as the 1970s, in some states of the United States--such as New York, the state I grew up in--ordinary retail were not allowed to be open on Sundays. Of course many exceptions were made, for "necessary" services--police, fire, hospitals, drugstores, and, usually restaurants.
