Quadragesima, Forty Days and Forty Nights.
Lent, in Christian tradition, is the period of the liturgical year leading up to Easter.
Conventionally it is described as being forty days long, though different denominations calculate the forty days differently. The forty days represent the time that, according to the Bible, Jesus spent in the wilderness before the beginning of his public ministry, where he endured temptation by Satan.
In Latin the term quadragesima (translation of the original Greek tessarakoste, the "fortieth day" before Easter) is used.
