Etymology

Old English mōnandæg "Monday," literally "the moon's day," a translation of Latin dies Lunae "day of the moon"

Word Origin
In ancient times, it was believed that there were seven "planets," one of which was the moon. The seven days of the week were named after the seven "planets" in Latin. One of the days was named dies Lunae, which means "day of the moon." The Latin name was later translated into other languages. In Old English, dies Lunae became mōnandæg. The word Monday comes from the Old English mōnandæg.
