What does the name Sunday mean?
Sunday is the English name of the day, from Old English sunnandæg, 'day of the sun', itself a translation of Latin dies Solis. As a first name it follows the old custom of naming a child for the day of its birth; DMNES notes that the Latin name Dominic was likewise first given to children born on a Sunday, the Lord's day. In the US it is used mainly for girls.
