Septuagesima lasts from Septuagesima Sunday to Shrove Tuesday (the day before Ash Wednesday).

Its name means "Seventy," and recalls the Babylonian Exile. It is a time of preparation for Lent.

This season lasts 16 calendar days.

Its color is violet.

This season, also called "Quadraegesima," meaning "Forty," is a somber, penitential Season

lasting from Ash Wednesday to the Thursday before Easter.

It recalls Christ's 40 days in the desert, and the Israelites' wandering in the desert for 40 years.

"Passiontide" is the last two weeks of Lent, from Passion Sunday (the 5th Sunday of Lent) the day before Palm Sunday.

The second week of Passiontide is called "Holy Week."  The last three days of Holy Week

(Maundy Thursday, Good Friday, and Holy Saturday)

are called the Sacred Triduum.

Per the everyday calendar, Lent lasts 40 days + the six Sundays, but the Sundays aren't counted

as "Lent" because Sundays are always about the Resurrection and are joyous.

The season lasts 46 calendar days.

Its color is violet.
