From the Liturgical yearAlthough the law of fasting began on Ash Wednesday, yet Lent, properly so called, does not begin till the Vespers of Saturday. In order to distinguish the rest of Lent from these four days which have been added to it, the Church continues to chant Vespers at the usual hour, and allows her ministers to break their fast before having said that Office. But, beginning with Saturday, Vespers will be anticipated; every day (Sundays excepted, which always exclude fasting), they will be said at such an early hour, that when the faithful take their full meal, the evening Office will be over.
