It will be seen from the tables that the cycle and great cycle periods could round 

 themselves out in harmony with the law governing all the rest of the scheme only at 

 the expiration of the grand era. If the Mayas were consistent simply — if they did not 

 capriciously spoil a plan which their preliminary work outlined to perfection — then 

 the grand era must have been the crowning period of their scheme. It was the only 

 period there could possibly be of which every element of both calendars would be an 

 even divisor. Thus it comprised exactly : — 



20 grand katun rounds.
