Notice that the months of the year and the days of the month and year all come together with each other 12 times at the very beginning of each century for the first 12 years of that century.This can only happen during the twelve years obviously because there are only twelve months on a calender year on Earth. Although I understand that at one time there was a thirteen month calender,that was changed to a twelve month calender to coinside with certain events that are known to coming in the near future. What that is ,is up for discussion.

Some say it's the return of the Jesus Christ's thousand year reign.

Some say it's the return of Neburu, the dark twin of our own sun which has a 3,600 year eliptical orbit around our sun.which would put it's last visit around the time of Moses exodus from Eygpt as depicted in the famous movie with Charilton Heston as Moses "THE TEN COMMANDMENTS" seen every year at Easter.

Some say it's the time the Anti-Christ takes control over the earth as a result of all the havoc brought by this 10th planet as it is sometimes called.causing so much destruction that the people will be willing to follow who ever it is who promises to do something to save them.

Just as in the movie "THE TEN COMMANDMENTS" there will be three days of darkness caused by the passage of this massive planet as it passes ,also a hail of stones fall from the sky that burn with fire .I assume they would be large metiorites falling through the Earths atmosphere.that become small enough to appear as hail the likes of which we are all familiar with with the exception of the fact that they would be burning rather than being pieces of ice.as hail of freezing water is.

Plagues of locusts are caused by unusually hot tempertures as well.drought.So rain is probably rare at times and too much rain can cause flooding and insects to proliferate

A lack of rain makes it impossible for animals to hide from insects as the water they would normally hide in would be so low that it would not prevent them from being stung by the insects and then dying from diseases that would spred as a result of being stung..

In the movie the first born male children died.I've read that the first born usually slept on the first floor of their residence and the others slept in the upper levels of the house because the first level or lower levels were cooler and for this same reason grain was stored in cooler places as well .The fact is heavier gases tend to hug the ground where the tempatures are cooler.The thinking here is that the first born males were the ones who slept at the level that has the most desnse air layer.They also gathered the families daily portion of grain from the graineries and they may have sufficated as a result of breathing polluted air ,the same way someone going into any enclosed area that contained a poisoned atmosphere.would such as coal mines and the like.

Also it's been said that when the passage occurs the Earth would be turned over on it's axis and even stop rotating .If the Earth stops rotating there will be a sudden jerking of land masses as rotation stops and oceans ,rivers ,trees etc and everything not secured to the Earth somehow will all be moving in one particular direction as rotation stops .Since the Earth rotates east to west I would assume that the force at rotation stoppage would be from west to east -the opposite direction. Then after the passage and rotation starts up again the same thing will happen ,but in the reverse direction of the stoppage.During all this rotation stoppage the waters of the Earth will be moving in one direction then another just as when a sunami occurs,but much stronger.If this is the case it would be advisable to stay at least a few hundred miles away from the ocean and betwen 10-50 miles from any other large body of water in either direction east or west from  lakes and rivers depending on size distance and the direction of the movement during this passage.The passage itself is supposed to take one hour.The timeline between sighting with the naked eye and passage is only a few weeks.
