Correlation with Christian Chronology.
The day for day correlation rests broadly on the placing of the date on the Lintel of the Initial Series at Chichen Itza in the first occupation of that city according to the chronicles. More specifically it rests upon statements in Mayan and Spanish documents relating to the completion of tuns and katuns in the never-languishing day count. Also consideration must be given the so-called Year-Bearers, these being the first days of current years which furnish the designations for such years. Bishop Landa has a specimen Mayan year with its equivalent days in the Spanish calendar; this is the year 12 Kan corresponding to 1553-1554 A. D. and the day 12 Kan is found in the Long Count position 12.9.17.9.4, 12 Kan 2 Pop, July 26, 1553, Gregorian Calendar.
