The Frequency Distribution Of Traditional Catholic Fast Days

This short book tells you what percentage chance each day in the calendar year is a fast day according to the fast days of the Catholic Church in the 1950's. There are 53 fast days during the year. Only three (3) of the days are fixed on the same day each year. The other 50 fast days are based on the movable calendar of feast days in the Church. Many days during the year are can never be fast days. Other days are a near certainty. As 50 of the 53 fast days are based on when Easter is, knowing the probability of Easter days is essential to calculating the fast days. This is a fun little book to learn about the Catholic faith, math and the calendar.
