Feast of the Transfiguration of the Lord Jesus Christ is celebrated every year on August 19th or August 6th on the Julian calendar. On this day is celebrated the transfiguration of Christ on Mount Tabor, when the Lord appeared in His glory to the apostles Petar, Jakov and Jovan (Peter, James and John). For this event is spoken in three of the four Gospels: Matthew 17.1 to 9, Mark 9.2-8 and Luke 9.28 to 36.

According to the legend, to strengthen the faith of the apostles after his following suffering and death, the Lord Jesus Christ wanted to show at least some of his divine glory while he was still in human body shape. So he took Peter, James and John with him and went out with them at night on Mount Tabor and there he transfigured in front of them.
"And his face shone like the sun, and his clothing became white as snow, and besides him appeared prophets Moses and Elijah. ... Then, a bright cloud has covered the Lord and his apostles and voice came from heaven: "This is My beloved Son, listen to him." After they heard this voice, apostles had fallen on earth as dead and remained so, until the Lord approached and told them: "get up and do not be afraid" (Matthew 17). "

Once they climbed off the mountain, Jesus commanded them not to speak about what they saw until he rises.
Although the event is traditionally believed to have occurred 40 days before the crucifixion of Christ, it is celebrated 40 days before Krstovden (Holy Cross day).
