The Copts (Christians of Egypt), who belong to the Coptic Orthodox Church, observe fasting periods according to the Coptic calendar. In Coptic Orthodox Christianity, fasting is traditionally defined as going without water and food from midnight to sunset; after that time, the consumption of water and one vegan meal is permitted. The fasting periods of Coptic Christians are exceeded by no other Christian denomination except the Orthodox Tewahedo. Out of the 365 days of the year, Copts often fast between 210 and 240 days. This means that Copts abstain from all animal products for up to two-thirds of each year. Coptic Orthodox fasts have evolved over time to become more lengthy and severe. A lifestyle involving such fasts may have contributed to the pacifist mindset of the Coptic people for centuries. Married couples refrain from sexual relations during Lent "to give themselves time for fasting and prayer".
