12 Adar 2 is on 22 March, two days before Purim. One thing to consider is that as Nibiru approaches many devastating effects will occur on Earth. There will be a greater intensity of earthquakes, volcano eruptions and unusual weather patterns. We are seeing this already, but what will happen specifically on the 22nd of March, I don't know. The beginning of the devastation due to the tail accompanying Nibiru could possibly be the chaos of the 22nd.
I will continue to research Nibiru and try to pinpoint more accurately the events to come.
