If I recall correctly the ancient Mayan calender was actually two calenderS; Plural. It is taught they used 260 and 365 day calenders. These were used in conjunction to create a 52 Year CYCLE (18980 Days Exact)
Therefore I conclude there is no end to the Mayan Calender. If refering to the end of a cycle and beginning of a new cycle: the Mayans feared every single "endcycle" believing their dieties would not grant them another 52 years. This "end of the world scenario" happened every 52 years since then. And it is rather funny to see the Myths it has created. I would not lose a minute of sleep worrying about the end of the world during any further endcycles.
But interestingly enough the Mayans developed their calender well, considering they would generally survive 40-50 years and not see two exact dates.
also quote the oracles and where they said that,and give me proof of divine prediction. If you can not, please refrain from quoting said "Oracles"
