St. Swithin’s Day

When Swithin, the bishop of Winchester, England, died in 862, he was buried according to his wish, outside the cathedral in the churchyard, in a place where the rain from the eaves poured down. This request was reversed after his canonization, when clerical authorities tried to move his remains to a site within the church. According to legend, the heavens opened and there was a heavy rainfall—a show of the saint’s displeasure. This led to the popular belief that if it rains on St. Swithin’s Day, it will rain for 40 days; but if it is fair, it will be dry for 40 days. Discuss
