Is Sunday a free day in Lent?
In Latin-rite Catholic understanding, the 6 Sundays occuring during Lent are discounted, hence the Latin name for Lent, “Quadragesima”=”40-day-period” whereas if you count there are 46 days between Ash Wednesday and Easter. The reading in the Lauds (the Church’s morning prayer) for Lenten Sundays is Neh. 8,9b and 10 b, in which the people of God are urged not to cry and mourn , but be joyful on a day consecrated to the Lord. Hence, you can be joyful(but not altogether frivolous) on Lenten Sundays.
