Ash Wednesday, February 14, 2018 (no exception for St. Valentine’s day) and March 30, 2018, Good Friday are obligatory days of fasting and abstinence for Catholics. In addition, Fridays during Lent are obligatory days of abstinence.
For members of the Latin Catholic Church, the norms on fasting are obligatory from age 18 until age 59. When fasting, a person is permitted to eat one full meal, as well as two smaller meals that together are not equal to a full meal. The norms concerning abstinence from meat are binding upon members of the Latin Catholic Church from age 14 onwards.
During Lent, we are asked to devote ourselves to seeking the Lord in prayer and reading Scripture, to service by giving alms, and to sacrifice self-control through fasting and practice self-discipline in other ways throughout the season.
