List of dates predicted for apocalyptic events

This is not predicting an apocalyptic event. This is observing that modern star charting software predicts an astronomical configuration that exactly matches two verses in the Revelation of Jesus Christ. I have personally run the software back to -4000 BC and forward to +4000 AD and this configuration only appears once, on September 23-24, 2017.
Now if you do not find this interesting, then please remember this: When they tell you that you have to have a mark on your right hand, or on your forehead to be able to buy or sell anything, DO NOT TAKE IT! They will probably cut off you head, but that is better than what happens if the take the Mark of the Beast.
