It’s super helpful that each day of the week has its own name!  Without these names, it’d be really hard to keep track of our calendars – and there’d be no such thing as #MotivationMonday or #TacoTuesday! But why do the days of the week have the names that they do?  We asked language expert Amelia Tseng to help us find the answer.
