Here are some sources for dates that Satanists consider to be significant. One of the sources states the following regarding April 19 and the days after that:

April

19 – 25 Sacrifice preparation: kidnapping, holding and ceremonial preparation of person for human sacrifice.

25 The Da Muer ritual: Grand climax. Sex rituals and sacrifice of a woman or young girl.

30 Walpurgis night/Beltane: One of the most important nights on the satanic calendar. Blood rituals and human sacrifice take place.
