The second month — Uo — begins with 8 Kan; when we reach 13, which is now Muluc, we must follow it with 1 Oc, and so oh to the end of the year. The last day of Cumhu in this case will be 9 Akbal and the last of the five intercalated days 1 Lamat; it follows therefore that the first day of the next year will be 2 Muluc. If we run through this second year in the same way, commencing it with 2 Muluc followed by 3 Oc, 4 Chuen, and so on, we shall find that the third year will begin with 3 Ix; continuing this process we ascertain that the fourth commences with 4 Cauac, the fifth with 5 Kan, the sixth with 6 Muluc, the seventh with 7 Ix, the eighth with 8 Cauac, the ninth with 9 Kan, the tenth with 10 Muluc, the eleventh with 11 Ix, the twelfth with 12 Cauac, the thirteenth with 13 Kan, the fourteenth with 1 Muluc, the fifteenth with 2 Ix, and so on. From this we see that no year, after the first, commences with a day numbered 1 until thirteen have been completed, thus forming a period of 13 years, or as it is designated, "A week of years" or "Indication." By continuing the above process we shall find that no year will again commence with 1 Kan until 52, (or 13✕4,) — are completed.
