Especially since 676 divided by 13 equals 52. Who did the original math on that aspect. It seems odd that the 676 is only repeated three times, not four. It is in the Codex Ramirez that the set of 676 the calendar count here. The stone itself does not record any such number sequence, only the events indicated by glyph.

Our Saturdays and Sundays (as glyphs in a Maya agricultural calendar) not found on the Madrid M-12 to M-18 were not to be confusThere were only considered. to be working days, The new schedule was to have begun in the IXth century AD. during the Classic Maya period. Karle Taube in [1983,7] named the process after the Norse "Swiddin" farm method,:in his paper titled "The Classic Maya Maize God: A Reappraisal" [In Fifth Round Table, Pre-Columbian Art. Ed.: Merle Greene [1985, 171-181], San Francisco, California.]
The raw question is "Why would farmers who always followed the stars to plant, and reap their crops ever considered a 52-year cycle, when they lived in a 52-week, 360-day world before a major disaster struck the land?
It should be noted, Diego de Landa's manuscript which was revised by William Gates, included POPP as the first month.. Gates also claimed different euro-dates as the year included by de Landa before h died in 1575. It became clear that Landa's report to Rome was altered at a later date since Rome had not yet introduced 0 POP to Mesoamerica until 1583-4. This seems to have been a common procedure through the era of such translators.
The Borgia Codex count succeeded because it isolated the 260-day count of the Trecena in the middle of the 364 + 1. It inferred that the top and bottom rows were the Saturday and Sunday of our common calendar.
The strange vertical count of four-year bearers X 03 + 01 = 13 can be considered as a computer generated a program to create a LOOP, a long time before computers had even been a dream. When the 676 was divided by 13; the answer was 52. The Trecena then became a yearly item through Independent Invention. The 4-year Swidden "slash and Burn" re-cycle agricultural method of the Madrid Codex has been the honored method of the farming of the land which has been ignored as a useless calendar. Is it possible to return to ordinary 52-weekly year count instead of the inferred 52-year cycle? Our spinning earth can never accomplish a 52-year harvest because it cannot change its orbit.
