"Wards at St. Mungo's Hospital for Magical Maladies and Injuries are never busier than at Hallowe'en. There's still a wizard in there with his head on back to front from last year."
-- Stamford Jorkins, Ministry of Magic spokesperson (DP4)
Headline in the Daily Prophet about Ministry plans to curb wizarding Hallowe’en celebrations (DP4)
Hallowe'en is the one time of year when wizards can be "out and about" without arousing the suspicions of Muggles, so the plans announced by Minister for Magic Cornelius Fudge have not been received very well by the wizarding world. Celestina Warbeck, the singing sorceress, and others interviewed protest the decision. Dangerous Hallowe'en incidents involve exploding pumpkins and broom accidents, leading to busy wards at St Mungo's Hospital (DP4)
While the date printed on DP4 is 1 October 1999, the timeframe for these events is 1992-1993.
