and SL:
In the church, water is consecrated on January 18, on the day of the Divine Appearance. This water is called the godly water. And at 0 a.m. on January 19, the same act of water sanctification is read over the water and the water is considered to be Kreshenskaya. In principle, both water is the same in strength. But the greatest strength of holy water from 0 to 3 o'clock at night on January 19, during the days 19 - 20 - January 21, its strength slowly decreases and by the evening of the 21st the water becomes normal. So swimming in Baptism is best at night on the 19th from 0 to 3 nights
