The name of the holiday comes from the church date of honoring the memory of St. Philip II, who served as metropolitan in Moscow during the reign of Tsar Ivan the Terrible. On Philip's Day, the people's holidays stopped and people returned to their homework. In the evening, according to tradition, they heated the bathhouse and went to wash off the “dirt of Christmastide.” Among the people, the bathhouse was considered a place not only of cleanliness, but also of washing away various diseases and sins.
