According to the folk calendar - Fedorin's day

Fedorin Day is popularly celebrated on June 9 (May 27 according to the old calendar style). This day is named after the church date of honoring the memory of the holy virgin Theodora of Alexandria, who died for her faith in Christ in the 4th century. Theodora lived in Alexandria, kept a vow of chastity, and openly and fearlessly confessed her faith in the Lord during the period of persecution of Christians. The ruler told the girl to renounce her faith, but she refused. For this she was sent to be corrupted in a brothel, but Theodora was saved by the warrior Didimus. Having learned about what had happened, the bishop ordered both to be beheaded and the bodies of the martyrs to be burned. Among the people, Theodora was renamed Fedora. Residents believed that her tongue was caustic and sarcastic, so on this day the entire female family was forbidden to communicate and gossip among themselves. You couldn’t gossip about your neighbors, tell anything about your family, or share your innermost secrets, since Fedora could twist everything and spread the wrong rumor around the village. Women's gossip on Fedorin's day could lead to troubles in the family. It was also forbidden to quarrel within the family, and if anyone started, he was stopped. Each family kept their problems to themselves so that others would not find out about their bad life. A quarrel that started on Fedorin’s day could instantly spread throughout the entire village and tarnish the family’s reputation. The day was spent working in the gardens and doing household chores, but there was no point in picking up a broom and sweeping away the dust. Removing garbage from homes was prohibited because they believed that the brownie, the guardian of the household, went to bed behind a broom on this date. If you sweep the floors, you could accidentally sweep out the brownie, and then problems would begin in the household. To prevent him from running away, his hostesses cajoled him with treats: milk, porridge or bread. Treats for him were placed near the stove before bed. If on a Fedorin day you felt stuffy at dawn, you prepared for rainy weather during the day. Seeing worms in sunny weather meant an approaching thunderstorm. If the honeysuckle inflorescences emitted less odor than usual, then dry weather was expected. The abundance of morning dew foreshadowed a sunny day.
