{Shrove Tuesday}, the Tuesday following Quinguagesima Sunday,
   and preceding the first day of Lent, or Ash Wednesday.
Note: It was formerly customary in England, on this day, for
      the people to confess their sins to their parish
      priests, after which they dined on pancakes, or
      fritters, and the occasion became one of merriment. The
      bell rung on this day is popularly called Pancake Bell,
      and the day itself Pancake Tuesday. --P. Cyc.
