"Mayan" calender, Calender Round q.

I've been doing reasearch into the Mayan (omec) calender, and think I understand most of it, how the "end" is really just a reset of the Long-Count calender on21st or 23rd Dec 2012(depends which date equivilecie you follow-there are 3).

SO there is what is called the "Calender Round", which is just how long it takes for the same named day (i.e. 4 Ahau 8 Cumku), to come around. This equates to 18,980 days, or 52 years. For the Aztecs, who adopted the Mayan calender, this time at the end of the Calender Round was a time of public panic, believed that the end of the world was coming. When the Pleadies(popular constellation with creation myths!) crossed the horizon on 4 Ahau,8 Cumku, they knew the world would be granted another 52-year extension.

SO, My question is, does the end of a Calender Round by any chance also corospond with 2012? Just curious, as I'm realllly bad with math and am hard pressed to find the answer myself.
