RE: 21th dec 2012
21st dec is last day of mayan calendar. Its same as 31st dec is last day of english calendar. In tamil calendar we have only 60 years, it doesnt mean world will end in 60 years. After 60 years the cycle starts again like the same way the cycle of english calendar starts every jan 1st.
Similarly mayan cycle ends on 21st dec after which the cycle will start all over again
So no worry and panic :tup
