long count was affected when the initial series date at Chichen Itza was 
placed in the earliest occupation of this site in the historical summary. 
According to this correlation Katun 8 Ahau at the beginning of the his- 
torical summar}^ coincides with the round number 9-0-0-0-0, 8 Ahau 
13 Ceh, in the long count and the particular Katun 13 Ahau, completed 
early in the Spanish conquest of Yucatan, coincides with 12-9-0-0-0, 
13 Ahau 8 Kankin. 
c. That the much-discussed shift in the positions that the days could 
occupy in the months of the haab (whether real or apparent) had no effect 
on the continuity of day names determined by the permutation cycle and 
the ancient notation and that 7 Ix 1 Pop of the late Mayan statements 
must be regarded as equivalent to 7 Ix 2 Pop of the early Mayan state- 
ments. 
d. That the "y^^^ bearer" method of designating the haab in northern 
Yucatan, while frankly at variance with the classical philosophy of count- 
ing only completed time units, nevertheless was organically tied into the 
ancient day count and that a year bearer 7 Ix designated a haab beginning 
with a day 7 Ix 2 Pop in the long count. 
e. That the end of Katun 13 Ahau fell during the Spanish conquest of 
Yucatan in a year 7 Ix according to the following mathematical demon- 
stration : 
12-8-14-4-14 7 Ix 2 Pop 
13- 6 
12-9- 0-0 0 13 Ahau 8 Kankin 
/. That the year 7 Ix corresponded to the latter part of the European 
year 1535 and the earlier part of 1536 on reasonable evidence fixing the 
correlation of several year bearers in the year-bearer cycle (52 X 365 days). 
The ground having been laid in this fashion for a correlation of days 
the complete Mayan year given by Landa is brought into relationship 
with the long count as follows : 
a. This year was one marked by 12 Kan as year bearer and, therefore, 
corresponded in the current year-bearer cycle to 1 553-' 54. 
b. This initial day of the Landa year, namely, the day 12 Kan 1 Pop 
in the late Mayan nomenclature or 12 Kan 2 Pop in the ancient nomen- 
clature, equaled 12-9-17-9-4, 12 Kan 2 Pop in the long count and it 
likewise equaled July 16, 1553, in the Julian Calendar and July 26, 1553, 
in the Gregorian calendar. 
Having made this fundamental correlation it is evident that account 
must always be taken of the fact that the Mayan haab was a 365-day year 
while the Julian year had an average value of 365.25 days. Thus, if the 
first day of the year 12 Kan was July 26 in the year 1553, the first day of 
the year 6 Kan must have fallen on August 3 in 1521. 
Among the Aztecs there was no long count of days put down in a fixed
