Ash Wednesday and Good Friday are obligatory days of universal fast and abstinence. 

Fasting is obligatory for all who have completed their 18th year until the beginning of their 60th year. Fasting allows a person to eat one full meal. Two smaller meals may be taken, not to equal one full meal. 

Abstinence (from meat) is obligatory for all who have completed their 14th year of age. If possible, the fast on Good Friday is continued until the Easter Vigil (on Holy Saturday night) as the “paschal fast” to honor the suffering and death of the Lord Jesus and to prepare to share more fully and celebrate more readily his Resurrection. Fridays in Lent are obligatory days of abstinence (from meat) for all who have completed their 14th year. As always, anyone for whom fasting or abstinence would pose a health risk is excused. 

Saint Patrick’s Day (Friday, March 17) does not dispense from the obligation to abstain from meat.
