What seems to be a typical Deathday Party entails a candlelit dinner of rancid, mouldy food, the smell of which would cause a normal living creature to gag. The reason for this is apparently the claim that a ghost can "almost taste" seriously spoiled food.

Harry Potter, Ron Weasley, and Hermione Granger attended Nicholas de Mimsy Porpington's 500th Deathday Party in 1992. Sir Nicolas was deeply touched that the three students put in an appearance, in part because it gave him a certain status in the eyes of his fellow deceased.
