Orthodox Christians observe four extended fasting seasons per liturgical year—Advent (or the Nativity Fast); Great Lent; the fast before the Feast of Ss Peter and Paul (usually in June); and the Dormition Fast, which commemorates the falling asleep of Mary, the Theotokos. That adds up to more than a third of a year. During this time, Orthodox are asked to abstain from meat and dairy products, as well as alcohol and even olive oil, depending on what day of the week or month it is.
