Lent is a forty-day period before Easter. Lent is a season of soul-searching and repentance. It is a season for reflection and taking stock. Lent originated in the very earliest days of the Church as a preparatory time for Easter, when the faithful rededicated themselves and when converts were instructed in the faith and prepared for baptism. By observing the forty days of Lent, the individual Christian imitates Jesus’ withdrawal into the wilderness for forty days. Lent has been observed in the church since apostolic times.
      The last day before Lent (called Mardi Gras, Shrove Tuesday, Carnival, or Fasching) has become a last fling before the solemnity of Lent. For centuries, it was customary to fast by abstaining from meat during Lent, which is why some people call the festival Carnival, which is Latin for farewell to meat. The Great Lent always begins on Clean Monday, the seventh Monday before Easter, and ends on the Friday before Palm Sunday—using of course the eastern date for Easter. The Lenten fast is relaxed on the weekends in honor of the Sabbath (Saturday) and the Resurrection (Sunday). The Great Lent is followed by Lazarus Saturday and Palm Sunday, which are feast days, then the Lenten fast resumes on Monday of Holy Week.
      According to the Bulgarian Orthodox Church, this period of time is known as the Great Lent, and Sundays are not skipped when counting. So, Lent begins on what is known as "Clean Monday," the seventh Monday before Easter, and ends on the Friday before Palm Sunday.
