According to Orthodox tradition, January 14 is dedicated to the memory of Saint Basil the Great (330–379 AD). This is the first day of the new year according to the old calendar, and it was celebrated with particular grandeur.
It was customary to celebrate with the eldest in the family. Relatives would come to him the day before Vasily's Day and stay until the morning. At dawn, each family member would go to the well or river to wash their face with the New Year's water to be healthy all year round. Also, carolers would go from house to house, and the hosts would bring out prepared treats for them.
Weather Omens
On Vasily's Day, people usually predicted the weather based on the wind: a northern wind meant a cold summer, a western wind indicated bad weather, an eastern wind suggested a dry season, and a southern wind promised warmth.
If it rains — expect snow by Easter. Icy roads — a sign of a good harvest. A waxing moon — for a spring with plenty of water. Snow in the morning — winter will be snowy, and spring will be late. Snow all day — a warm summer is ahead. Thaw — a cold summer is coming. Starry night — a good berry harvest. Blizzard and snowstorm — a good nut harvest.
