Black Friday

Etymology
From. Friday is an ill-omened day according to ancient superstition, so a Friday that was darkened by another ill-omen (such as being the 13th) or an actual disaster became known as "Black Friday". Philadelphia police applied the term to the day after Thanksgiving because the large number of people out shopping made traffic chaotic. Later, PR efforts purposely invented the incorrect, more positive "etymology" (which is a very popular urban legend and false etymology that was even in Wiktionary from 2008 to 2015) that the name was given because this day is supposedly the first day of the year on which retailers typically posted profits ('in the black') rather than losses ('in the red').
