The feast itself lasts three days. The first day is known as "Trinity Sunday"; the second day is known as "Spirit Monday" (or "Monday of the Holy Spirit"); and the third day, Tuesday, is called the "Third Day of the Trinity." The Afterfeast of Pentecost lasts for one week, during which fasting is not permitted, even on Wednesday and Friday. In the Orthodox Tradition, the liturgical color used at Pentecost is green, and the clergy and faithful carry flowers and green branches in their hands during the services.
