"Don J. P. Perez positively states, that the fundamental rule is never to interrupt either of the series of names or of days. Thus, inasmuch as the last supplementary day of the first year of the cycle (1 Khan) is 1 Lamat; and as, in the order of the days of the month, the day called "Muluc" immediately follows the day Lamat; the ensuing year 2 Muluc commences with the day 2 Muluc, in the same manner as the year 1 Khan commences with the day 1 Khan. It is the same with the other years; so that the first day of every year has the same name and numerical character as the year itself.
"Don J. P. Perez acknowledges that amongst the few mutilated remains of Indian manuscripts or paintings, he has not been able to discover any trace of an intercalation, either of one day every four years, or of thirteen days at the end of the cycle, though he presumes that they had indubitably either the one or the other.
"The Yucatan cycle of fifty-two years, differed in no other respect from that of the Mexicans. The combination of the two series of twenty and thirteen days is used in the same manner in both calendars for the purpose of distinguishing the days of the year.
