Quinquagesima Sunday is also known as the Sunday before Lent, as it marks the start of the 50-day season of Lent leading up to Easter. It is also referred to as Shrove Sunday, Pardon Sunday or Carnival Sunday. These synonyms reflect the various traditions and cultures that have incorporated this religious observance into their calendars. Shrove Sunday comes from the word "shrive," meaning to confess and be absolved of sins before Lent. Pardon Sunday refers to the remission of sins through penitence and prayer, while Carnival Sunday is synonymous with feasting and revelry before the somber period of Lenten fasting and reflection begins.
