For the second part if this question, which... like Eleni's questions are not so easily answered.
The timing of the Yugas is difficult to comprehend. But to understand this just a little bit further, understand that the physical representation of the human being was most probably created the beginning of Kali Yuga, the Yuga we are in today. The Yugas before that were metaphysical representations of a Yuga, but equally as important and real.
It is very difficult to understand that actual timeframe of these yugas, for our minds can not understand the multitude of facits that are expressed in each yuga
For most of us we need to accept the place that we are in, and see the clarity of its existence that was written and foretold so many millions of years ago,
Like a circle that is never-ending are our lives ,until we reach a God realized existence, that is when this cycle ends and yes, a new one begins.
The Yuga's are all just greater cycles. As far as when they started and when will they end? That goes under the never ending discussion of yogic philosophy! We will all know the answer on that one glorious day that we become God Realized! Let us all know what the real truth is! Till then, we will collectively continue to move forward in faith.
It does say 12 years to change a cycle or a samskara, but during that time we can be working on a few things at the same time.
For instance we can work on Ahimsa as well as Pratyahara, so the culmination of work happens within those 12 years of dedication. the 13th year that they speak of is the year that God Realization is recognized.
None of this is easy, but once we begin on this journey it appears to be easier to do the right thing than not.
