The liturgical Forefeast of Theophany begins on January 1, and concludes with the Paramony on January 5.

The Eve of the Feast is called Paramony
Paramony is observed as a strict fast day, on which those faithful who are physically able, refrain from food until the first star is observed in the evening, when a meal with wine and oil may be taken. On this day the Royal Hours are celebrated, thus tying together the feasts of Nativity and Good Friday. The Royal Hours are followed by the Divine Liturgy of St. Basil which combines Vespers with the Divine Liturgy. During the Vespers, fifteen Old Testament lections which foreshadow the Baptism of Christ are read, and special antiphons are chanted. If the Feast of the Theophany falls on a Sunday or Monday, the Royal Hours are chanted on the previous Friday, and on the Paramony the Vesperal Divine Liturgy of St. John Chrysostom is celebrated and the fasting is lessened to some degree.

Blessing of Waters
The Orthodox Churches perform the Great Blessing of Waters on Theophany. The blessing is normally done twice: once on the Eve of the Feast—usually at a Baptismal font inside the church—and then again on the day of the feast, outdoors at a body of water. Following the Divine Liturgy, the clergy and people go in a Crucession (procession with the cross) to the nearest body of water, be it a beach, harbor, quay, river, lake, swimming pool, water depot, etc. (ideally, it should be a body of “living water”). At the end of the ceremony the priest will bless the waters. In the Greek practice, he does this by casting a cross into the water. If swimming is feasible on the spot, any number of volunteers may try to recover the cross. The person who gets the cross first swims back and returns it to the priest, who then delivers a special blessing to the swimmer and their household.
