I'd bet money I tirn out to be right.
And of course they would. This "Calendar" sounds like a ham-handed attempt to provide info on "Satanism." I don't think the calendar was actually "explicit" in the normal sense of the word.
Dr. Ellis: The panic affected much of the English-speaking world from the mid-1960s to the early 1990s. Not only the United States, but Canada, the United Kingdom, Australia, New Zealand, and even South Africa and Zimbabwe were touched in some way by the rumors. The gist is that a large number of underground organizations were brainwashing members, often through initiation rituals of mind-numbing depravity, and then encouraging them to go out and commit heinous crimes including child abduction, rape, and murder. The contemporary version called these groups “Satanic cults,” but the ideas they were based on had been recycled from earlier conspiracy theories in which the bad guys had been Communists, Jews, Masons, etc.
Watchman: Recently animal slayings in Ohio were blamed on Satanic ritual slayings but the media later abandoned that theory as false. Is there a stereotype of Satanism and so-called “satanic ritual crime” that continues to play a part in American culture?
Dr. Ellis: Sadly, yes. Probably the most widespread stereotype is that “Satanic cults” can be identified through some sort of shared set of symbols or predictable holidays. Scott Peterson’s attorneys made much of the fact that Laci was reported missing on Christmas Eve, supposedly a “Grand Climax” in a Satanic calendar. Previously, a woman had disappeared on May 1, another “Grand Climax” date, and was subsequently found murdered in ways similar to Laci Peterson. This correlation superficially makes sense until you begin to look closely at the alleged Satanic calendars. First, none of these have ever been traced to the practice of any observable or documented cult. The calendars appeared first in 1987, as part of an overblown article in Passport Magazine alleging a nationwide conspiracy of ordinary-seeming citizens in the ritual abduction and murder of two million children per year. (If true, this meant that over half the children born in the US every year died in Satanic cult sacrifices.) As critics later pointed out, the dates were borrowed uncritically from a wide range of sources, including the 15th century witch-hunters’ manual, the Malleus Malificarum.
Even if we take the calendar seriously, critics have noted that it covers some 123 days out of the year, or one out of every three days. Given the uncertainty of when a given crime was committed (police think Laci Peterson might have been killed on December 23 and reported missing the next day), it’s possible to link just about any crime to a “Satanic holiday.” In any case, is it likely that any cult would be able to fulfill the prescribed numbers of abductions, rapes, and ritual murders without drawing police and (more importantly) media attention to the pattern?
Sadly, the calendar is available from over a hundred websites, nearly all Christian in orientation. In at least one case, a pedophile was apprehended with a copy of this document in his pocket: he was not a Satanist, but had gotten the list from a Christian-sponsored public event supposedly warning against cults. Yet as the calendar had recommended sexual abuse of a child on an upcoming date, he had carried it out to the letter. Christian organizations need to ask whether the information they circulate in fact discourages evil acts or, paradoxically, could encourage some people to commit the crimes we decry.
