Thanks Hunton Peck. This is an interesting coinky-dinky — the alleged psychic, Edgar Cayce, referred to a 40 year period of Earth disasters running from 1958 to 1998 — but there’s an explicit reference in one of his purported readings to a different calendar, which adds on the length of Christ’s life (starts at the Crucifixion, rather than birth), hence add about 28 years (Herod died in 4 BC); the 40 year period runs from circa 1986 to 2016.
Oops.
