The churches are decorated with greenery, and among the Russians the clergy and faithful carry flowers and green branches in their hands during the services. Pentecost is a traditional time for baptisms. The week prior to the feast is known as "green week", during which all manner of plants and herbs are gathered. The Sunday of Pentecost is called "Trinity Sunday," the next day is called "Monday of the Holy Spirit", and Tuesday of Pentecost week is called the "Third Day of the Trinity." The whole week following Pentecost is an important ecclesiastical feast, and is a fast-free week, during which meat and dairy products may be eaten, even on Wednesday and Friday.
