Pope Shenouda III

There is however a minimum time of abstinence, which varies depending on the fast. The minimal fast period for Lent should be higher than for the rest of the fasts and the minimum during the Passion Week is higher than that of Lent. Some are able to fast from Maundy Thursday up to the Easter Mass and others on the day preceding Christmas or Epiphany. As for the weak, their endurance is limited.
