Strikingly similar folkloric aspects of the number 13 have been noted in various cultures around the world: one theory is that this is due to the cultures employing lunar-solar calendars (there are approximately 12.41 lunations per solar year, and hence 12 "true months" plus a smaller, and often portentous, thirteenth month).

Full moons

A year which contained 13 full moons instead of 12 posed problems for the monks who were in charge of the calendars. "This was considered a very unfortunate circumstance, especially by the monks who had charge of the calendar of thirteen months for that year, and it upset the regular arrangement of church festivals. For this reason thirteen came to be considered an unlucky number."

However, in a typical century, there will be about 37 years which have 13 full moons compared with 63 years with 12 full moons, and typically every third or fourth year would have 13 full moons, making it a reasonably common occurrence, unlikely to tax monks any more than leap years.

A repressed lunar cult
