Some time ago I saw a book that explained according to the Author how the signs of the Zodiac represented Jesus, the Disciples and various Gospel details. This business seems to be a variation on the theme. I predict that after 23 September pundits will be combing the world news searching for an event that they can claim to be connected with this. In the UK we have a magazine that is issued every year called Old Moors Almanac that supposedly predicts major world events for the coming year based on Astrology. Sometimes the writers get a thing right but more often they don't.
The Zodiac is a corruption of the MAZZAROTH referenced in Job which is biblical....God has consistently used heavenly signs to announce particular events.....even the death of Christ on the cross resulted in three hours of utter darkness and earthquakes which were also recorded by no less that 4 secular sources....point being....we can look at the stars and see these events lining up in the heavens and Jesus himself said that his coming (Parousia) would be preceded by fearful sights, signs and events in the heavens (Luke 21)
No one is setting dates.....just that when combined with worldly events especially in the Middle East it seems that we are on the cusp of something major and of biblical significance......that is all I am saying....
