in
Brittany, 1893 The question would naturally arise as to why the celebration falls on June 24 rather than June 25 if the date is to be precisely six months before
Christmas. It has often been claimed that the Church authorities wanted to
Christianize the pagan
solstice celebrations and for this reason advanced Saint John's feast as a substitute. This explanation is questionable because in the Middle Ages the solstice took place around the middle of June due to the inaccuracy of the Julian calendar. It was only in 1582, through the
Gregorian calendar reform, that the solstice returned to June 21 as it had been in the fourth century. Therefore, a more likely reason why the festival falls on June 24 lies in the Roman way of counting, which proceeded backward from the
Kalends (first day) of the succeeding month. Christmas was
"the eighth day before the Kalends of January" (
Octavo Kalendas Januarii). Consequently, Saint John's Nativity was put on the "eighth day before the Kalends of July." However, since June has only thirty days, in our present (Germanic) way of counting, the feast falls on June 24.
Customs All over Europe "Saint John's fires" are lit on mountains and hilltops on the eve of his feast. As the first day of summer, Saint John's Day is considered in ancient folklore one of the great "charmed" festivals of the year. Hidden treasures are said to lie open in lonely places, waiting for the lucky finder. Divining rods should be cut on this day. Herbs are given unusual powers of healing, which they retain if they are plucked during the night of the feast. In Germany they call these herbs Johanneskraut (St. John's herbs), and people bring them to church for a special blessing. In Scandinavia and in the Slavic countries it is an ancient superstition that on Saint John's Day witches and demons are allowed to roam the earth. As at Halloween, children go the rounds and demand "treats," straw figures are thrown into the flames, and much noise is made to drive the demons away. ==In Mandaeism==
