Quinquagesima is the name for the Sunday before Ash Wednesday. It was also called Quinquagesima Sunday, Shrove Sunday or Esto Mihi. The name originates from Latin quinquagesimus (fiftieth), referring to the fifty days before Easter Sunday using inclusive counting which counts both Sundays (normal counting would count only one of these). Since the forty days of the Lenten fast included only weekdays, the first day of Lent, Ash Wednesday, succeeds Quinquagesima Sunday by only three days. The earliest Quinquagesima Sunday can occur is February 1 and the latest is March 7.
