According to the folk calendar - Rodion and Erast, Rodion Icebreaker

This day is associated with the apostles of the seventy, Erastus and Herodion. Sometimes November 23 was called Erast - a strong crust or Rodion Icebreaker. This is due to the fact that by this time the crust was getting stronger and stronger, but it was still impossible to cross the reservoirs, otherwise you could break the ice and fall into the water. On Erast it was customary to help those in need. People distributed unnecessary clothes and fed the poor. On this day, hunters went out for their first winter hunt. But other people tried not to leave the house unless necessary. Women did handicrafts and household chores, men prepared equipment, shoes and clothes for winter. According to the signs on November 23, they determined the weather: if everything around is covered with frost, then frosts will soon hit, and if a lot of snow fell on Rodion, then it will soon become warmer.
