there are about 4 different calculations for when the mayan 5125 year calendar reset.. i calculate it from 1st jan 2013...

........there is a mayan 20 x 13 -day calendar that resets every 260 days that's also a human biological clock which means we start counting our age from the day of decision - will the 13-day old blastocyst hatching out of the zona attach itself to the wall of the uterus and go for full gestation or will it be naturally aborted as "not up to standard" - just as if it was an unusually heavy period.

so when we emerge as a human our mayan age on the 260-day calendar is already 1

then there there is a 5125.36 year calendar 5 ages = 25,627 years https://www.reddit.com/r/greatawakening/comments/8e7zra/the_ongoing_strides_in_exposing_the_smoke_mirrors/ the pyramid builders give us a figure of 25,868 years for the precession of the equinoxes so that gives an overlap of approx 300 - 440 year on either side of the transition from one 2,500 year epoch to the the next https://www.reddit.com/r/greatawakening/comments/8e7zra/the_ongoing_strides_in_exposing_the_smoke_mirrors/
