Saint Monday
（重定向自Case of the mondays）
Saint Monday is the tradition of absenteeism on a Monday. Saint Tuesday is the less common extension of this to a Tuesday.
The tradition of taking Monday off has been common among craft workers since at least the seventeenth century.
In his autobiography, Benjamin Franklin refers to the practice, saying of his youthful employment in a London printing house, "My constant attendance (I never making a St. Monday) recommended me to the master".
