Counterpoint: it can be a coincidence.
It's like the birthday paradox, chances of two people in a group of only ~23 sharing a birthday (not year but day) is 50% - seems impossible but in fact just a coincidence of basic numbers and probability. With a fairly large number of posters here sharing dates about 'things happening', coincidences of dates that feel meaningful are inevitable. (Particularly because we only make the claim about the causal connection after the fact)
(I say as I throw a pinch of salt over my shoulder and say 'fu, fu.')
