Monday:


second day of the week, derived from the Anglo-Saxon monandaeg, which means “the Moon’s day”. Its Latin equivalent is dies lunae,”day of the Moon”. For the Anglo-Saxons the second day was sacred to the goddess of the moon. In German the second day is Montag; in French, lundi; and in Italian, lunedì.
“Blue Monday”, a term used to indicate the dismal beginning of the working week, was originally used because, on the Monday before Lent, churches were draped in blue cloth, symbolizing penitence.
