Fasting is a practice in several Christian denominations or other churches. Some denominations do not practice it, considering it an external observance, but many individual believers choose to observe fasts at various times at their own behest. The Lenten fast observed in the Catholic Church and the Eastern Orthodox Church is a forty-day partial fast to commemorate the fast observed by Christ during his temptation in the desert. This is similar to the partial fasting within the Ethiopian Orthodox Church (abstaining from meat and milk) which takes place during certain times of the year and lasts for weeks. The Bible sets aside one whole day a year for fasting, The Day of Atonement. Leviticus 23:27, 32 (CEV) says "Everyone must go without eating from the evening of the ninth to the evening of the tenth on the seventh month which is the Day of Atonement."
