What is your opinion regarding 21.12.2012 Doomsday??

According to the Mayans, 21.12.2012 is the end of their Mayan calendar, PLUS the end of the universe (i.e., Doomsday of course).
Ironically, this date (as shown above) falls on Friday, on which we Muslims also believe that Doomsday will occur on Friday, no doubt.
So, guys & gals (who are Muslims), I want to know what's your opinion regarding this 21.12.2012 Doomsday.
And for your information, in fact, out of all of the tribes around the world, the Mayans are the only tribe members who are good astronomers & are famous for making such successful prophecies such as the moon eclipse & the 2004 Indian Ocean Tsunami (if I'm not mistaken).
