Beginning on the evening of Palm Sunday and continuing through the evening of Holy Tuesday, the Orthodox Church observes a special service known as the Service of the Bridegroom. Each evening service is the Matins or Orthros service of the following day (e.g. the service held on Sunday evening is the Orthros service for Holy Monday). The name of the service is from the figure of the Bridegroom in the parable of the Ten Virgins found in Matthew 25:1-13.
