To the best of my knowledge, Catholics do not celebrate length.
I think you may be asking why Catholics "celebrate" Lent. This is the 40 days preceding Easter and it is in remembrance of when Christ, after his baptism, was led into the desert by the Holy Spirit to fast and pray for 40 days. It is a time of penance, meditation, prayer and fasting. Since there is fasting (except for Sundays) and Lent always begins on a Wednesday, the day before Lent is Mardi Gras (Fat Tuesday) - last chance to 'party'. See new advent dot org and search the Catholic Encyclopedia for more detail.
