On 19th of January each year, many of the Orthodox Churches who still follow the Old Church Calendar celebrate one of the 12 most important feasts in Church life.
On this date Russian Orthodox Church Serbs, Ukrainians, Molodovan and the Patriarchate of Jerusalem are celebrating.
In Bulgarian Orthodox Church, Greek and Romanian, Croatia and other Eastern Orthodox who follow new calendar, The Day of Jordan (The day in which Jesus was baptized in Jordan) is celebrated on 6-th of January on the same date when Russian, Serbs, Ukrains and other Orthodox Churches using old calendar celebrate Nativity of Christ.
The feast of Baptism of Christ is one of the most ancient feasts in Church history.
Here is the Church troparion as sung on (Jordanov den – as we say in Bulgaria – St. John's Day).

It is interesting fact to know that in Roman Catholic Church and most western countries the feast of Epiphany is known as the feast of Three Magi Kings (The Three Wise man who came to bring expensive gifts to venerate the birth of King of Kings the Lord Jesus Christ). Many of the traditions accepted in Western Countries for Epiphany are very similar to traditions practiced by countries where there is widespread Roman Catholicism influence. I've red about the feast as practiced in various countries in Western Europe and it appears many of the traditions are similar as paradigm to German and Dutch SinterKlaas (Saint Nicolas) feast. It is interesting fact that some of the traditions like the releasing of the Cross in Rivers by the Orthodox Priest and cross take out by the bravest man in Bulgaria is also practiced in Greece, Serbia, Macedonia, Bosnia and Herzegovina and probably some Orthodox Christian regions of countries belonging to ex-YugoSlavia.
