Laetare

Laetare Sunday (Church Latin: [leˈta.re]; Classical Latin: [lae̯ˈtaːre]; English: ) is the fourth Sunday in the season of Lent, in the Western Christian liturgical calendar. Traditionally, this Sunday has been a day of celebration within the austere period of Lent. This Sunday gets its name from the first few words (incipit) of the traditional Latin entrance verse (Introit) for the Mass of the day. "Lætare Jerusalem" ("Rejoice, O Jerusalem") is Latin from Isaiah 66:10.
