The custom of Kalogeros takes place on Tyrini Sunday (beginning of Lent). Its roots are ancient, and it emphasizes our dependence on nature. The custom was brought to Drama by refugees from Eastern Thrace.

Kalogeros (monk) wears animal skins and disguises himself as an animal. Around his waist hang bells, one of which is a symbol of fertility. The rest of the participants are dressed in black. The party is accompanied by traditional musical instruments.

The custom has 5 phases: visits to all the houses of the village, tug-of-war, reconstruction of plowing and sowing, virtual death of Kalogeros and finally, dance.
