According to the folk calendar - Pakhom-Bokogrey, Pakhom Teply

According to the folk calendar, Pakhom-Bokogrey is celebrated on May 28 (May 15, old style). The day is also called Pakhom Warm. The name of the holiday is taken from the church date of honoring the memory of St. Pachomius the Great. Pachomius lived in Thebaid in Egypt in the 3rd and 4th centuries. While doing military service, he learned about the Lord from Christian friends. Returning home, the warrior converted to Christianity and underwent baptism. Pachomius went to live in the desert, and 10 years later he built a monastery. For his wise guidance and righteous life, God rewarded the saint with the gift of miracles - Pachomius could heal seriously ill people through prayer. The people called Pakhom Bokogrey or Teply. This was associated with the return of southern winds and the onset of summer heat. Based on this day, the future summer was determined; if the weather was clear, the summer was expected to be hot, with rare rains. Cloudy weather, on the contrary, promised a cool summer season. But the crimson dawn foreshadowed frequent fires. On Pakhoma-Bokogrey there was a custom to sow the remaining wheat, believing that it would grow and give a rich harvest. However, it was necessary to plant before noon, otherwise the shoots would not germinate well. On this day it was not recommended to sow other grain crops, believing that they would not be accepted. If low-flying moths were observed on Pakhoma-Bokogrey, they were preparing for a generous harvest of grain crops. Smoke spreading along the ground predicted rain, and smoke rising into the sky predicted clear weather. If the wind blew from the east during the rain, then they prepared for the end of the bad weather. Flying cobwebs in the air foreshadowed a sultry summer.
