Walpurgisnacht
In the Roman martyrology,
St. Walburga's Feast -- a day that commemorates
the date of her canonization -- is on May 1, though it isn't celebrated
liturgically on the 1962 calendar [nor is it anywhere to be found in my 1945 Fr.
Lasance New Roman Missal]. Her Feast is, however, a great holiday in many
European countries, especially in Germany, Finland, Sweden, and Eastern
European countries, and the celebrations begin on its eve -- the night of 30
April -- a time known as Walpurgisnacht.
