One must also take into account human error. It would not be the first time in history that researchers were slightly off center on the correct date of an event taking place. So Nibiru’s arrival would not be the first miscalculated event in the history of mankind. So it very well could be possible that Nibiru is set to arrive in july 2013 if it is going to arrive at all.
According to those who research Planet Nibiru, The recent barrage of comets entering earths atmosphere most notably the event in Chelyabinsk Russia are a sign that Nibiru is in fact on its way towards planet earth. According to researchers on the subject of Nibiru, As Nibiru passes through our solar systems asteroid belt. Its gravity effects those said asteroids and launches them off in many unpredictable directions some of which are headings towards earth. We have all seen the footage of the meteorite falling through the skies of Russia. Along with all of its side effects such as the massive sonic boom that causes millions in damages and lots of injuries. It seems that evidence is stacking up and those meteor fragments could very well point to the arrival of Planet Nibiru.

Is this all real or is it just the dreams of mad men and women ? You decide !
