According to the folk calendar - Prokhory-Parmeni

The national holiday of Prokhora-Parmena falls on August 10. In Orthodoxy, this day is associated with the names of the apostles Prokhor and Parmen. According to Christian legend, the twelve apostles called together seventy of their disciples and invited them to choose seven people to resolve everyday issues. These people were supposed to cook food and give alms. Their work would help free the apostles for their main mission - spreading Christianity. Prochorus (disciple of the Apostle Peter) and Parmen (disciple of John the Theologian) were among the chosen ones. Later, Prokhor became a bishop in Nicomedia and contributed in every possible way to the spread of Christianity. Parmen's further fate is shrouded in mystery. It is only known that it was he who was the author of the biography of his teacher. On Prokhorov Day, people honored blacksmiths, without whose labor peasant life would have been difficult. People of this craft shoed horses, repaired equipment, and made tools. The blacksmith helped the peasants not only in everyday life. He was credited with magical abilities, because he dealt with fire and metal, and sharply sharpened objects protected him from evil spirits. What added mystery to the image of the blacksmith was the fact that his home and forge were located far from the village. There was a popular belief that the most important thing on this day was not to buy or sell anything. Even the exchange of anything was prohibited. It was believed that a purchased or exchanged item would quickly become unusable, stolen or lost. On Prokhor, the pear harvest usually began. The peasants believed that if by August 10 the potato tops began to wither, then they could dig them up. Housewives on this day prepared pear pies and boiled new potatoes. Usually the weather on Prokhorov day is sunny. It is generally accepted that its harbingers are heavy dew in the morning and high-floating clouds. Bad weather that begins on Prokhor most often drags on for a long time.
