Last year also a similar kind of event had occurred. When I was doing my summers in Ranbaxy Fine Chemicals Limited, a celestial event took place. It was called as the Transit of Venus. It too happened on a very similar kind of date 08-06-04. Just observe that the three figures in the date are only 2 apart. The photo of this event is also shown below.
On this day venus drift across the face of the sun as Venus passed between the sun and earth. This was one of the rare celestial spectacle and a transit of Venus is so rare that, up to June 8, 2004, no human then alive had witnessed this celestial event. Simple as transits may seem, they are instrumental in defining our place in the cosmos. Historically global expeditions timed transits of Venus to quantify the size of the solar system. Then next transit of Venus is scheduled on June 5-6,2012.
