Christian feast days: Saint Walpurga (she was canonised on 1 May c. 870 and Walpurgis Night is celebrated 30 April)

Walpurga or Walburga was an Anglo-Saxon missionary to the Frankish Empire. She was canonized on 1 May c. 870 by Pope Adrian II. Saint Walpurgis Night is the name for the eve of her feast day in the Medieval period, which coincided with May Day; her feast is no longer celebrated on that day, but the name is still used for May Eve.

Walpurgis Night, an abbreviation of Saint Walpurgis Night, also known as Saint Walpurga's Eve and Walpurgisnacht, is the eve of the Christian feast day of Saint Walpurga, an 8th-century abbess in Francia, and is celebrated on the night of 30 April and the day of 1 May. This feast commemorates the canonization of Saint Walpurga and the movement of her relics to Eichstätt, both of which occurred on 1 May 870.

February 25 is the 56th day of the year in the Gregorian calendar; 309 days remain until the end of the year.
