At the beginning of the 20th century, Sándor Koltay, a teacher, urged to keep alive the custom of St. Gregory Procession on March 12. The origin of the custom goes back to the Middle Ages, when begging students roamed from house to house in the village. Starting from the 17th century, the custom also included inviting new students to the school. From the 1860s onwards, it became general, organized by teachers who went for the procession together with the pupils. The song goes, “It is the day of doctor St. Gregory's, the famous teacher...”, and it is sung to this day by the Ivánc Folk Song Circle. It was a well-known Slavic custom in Hungary, but it was practiced mainly in Transdanubia.
