Nevermind that the Jewish Sabbath starts at sundown on Friday and ends at sundown on Saturday, most Christians view Sunday as the Sabbath. Various state blue laws restrict commerce on Sunday -especially in the area of liquor sales. Today's map shows the 12 states (red) that retain such laws. In a number of these 12 states, beer and wine sales are allowed after church gets out (i.e. after 12pm or 1pm).
Curiously, Texas also requires car dealerships to close either Saturday or Sunday each weekend.
