According to the folk calendar - Levon Borage, Levon Konoplyanik

Levon Borage, also called Hemp, is popularly celebrated on June 5 (May 23 according to the old calendar style). Levon named the holiday in the name of Saint Leonty of Rostov, a bishop revered on this day by the Orthodox Church. Leonty was born in Constantinople in the 11th century into a Russian family. There is little information about his life, however, sources claim that he became a monk at the Kiev Pechersk Lavra. When Leonty was elevated to bishop, he went to Rostov, where he led the Rostov see. The bishop led an active struggle against idolaters and led many to the Christian faith. He died around the 1070s. The people renamed Leonty's name to Levon, and called him Borage for the tradition of planting cucumbers. Their planting was hidden from surrounding eyes, even from relatives, so as not to jinx the future harvest. Then they read a conspiracy for successful growth. The first grown cucumber was also hidden, it was picked and buried in the ground, believing that this would protect the entire crop from the envious evil eye. Another name of the day was Levon Konoplyanik. This date was considered successful for sowing hemp. In order for it to bear fruit well, peasants put a blessed egg into the seeds at Easter, and after sowing the hemp in the ground, the eggshells were crushed and scattered across the field. Hemp was popularly considered to be as important a crop as flax. Previously, ropes and thread were made from it. The fabric turned out to be strong, low-elastic, but well suited for sewing thick fabric for bags, thick shirts, and bedspreads. Hemp inflorescences were a generous honey plant for bees, and oil was crushed from the seeds, adding it to porridge. Hemp seeds were added to bread, fried and eaten like sunflower seeds. Cannabis was also used in folk medicine. Its seeds were useful for stomach pain, had a diuretic, analgesic and anti-inflammatory properties. An infusion of its inflorescences was used for headaches and insomnia. The infusion from the seeds helped increase the milk supply of a nursing woman. If an abundance of gadflies were observed on Levon Borage, then a generous cucumber harvest was expected. Blooming rowan on this day foreshadowed a high yield of hemp crops. An abundance of midges promised warm weather. Impending precipitation was determined by dim stars at night.
