Vigil of Pentecost: Saturday is a day of fast and partial abstinence in preparation for the feast of the Pentecost. All baptized Catholics seven years and older may eat meat only once, at the principal meal. Those between the ages of 21 and 59 are also bound to observe the Church laws regarding fasting. Only one full meal is permitted on a fast day; two smaller meatless meals, sufficient to maintain strength, are permitted, but together they should not equal to a full meal.
