Pope Shenouda III
. Since days of fasting cover the major portion of the year. This bible chapter has remained for all year long to remind us of fasting, even during the days when there is no abstinence to allow us to maintain our daily prayers and remember God's blessing of food before we eat.
The ninth hour of the day actually coincides with three o'clock in the afternoon since the first hour of the day corresponds to six o'clock in the morning.
In any case, there is no need to elaborate further on this point since the period of abstinence differs from one person to another. The period of abstinence is left up to the Father confessor and to the spiritual condition of the person fasting.
