Since the year contained 365 days, and the day-signs were 20 in number, it is obvious that the year began on one of four days. These days, later called “year-bearers,” were, at the time of the monuments and the writing of the Dresden codex, ben, eznab, akbal and lamat, which correspond to the days which began the Mexican year, acatl, tecpatl, calli and tochtli. However, the year-bearers as given by Landa, and also as they appear in the Troano-Cortesianus codex, are kan, muluc, ix and cauac. This means that in the interval the commencement of the year had shifted (5 × _x_) + 1 days, _x_ being an unknown quantity. By this time too the long count in its most elaborate form seems to have been abandoned, and the katun became the highest unit, known by the name of its “initial” day, e.g. katun 6. ahau, or katun 4. ahau. It is this method of reckoning which is employed in the books of Chilan Balam. Most of the other races of Maya stock, as far as is known, possessed calendars which included a series of twenty day-signs (see Appendix I) combined with the numerals one to thirteen, but the count of the Kakchiquel was different, being purely vigesimal. The periods involved were one of 400 days (20 × 20), called _huna_, and a larger of 8000 days (20 huna), called _may_. The huna was known by its initial day _ah_ (corresponding to ben and acatl) together with the number which might be attached to it, and the time count dated from the destruction of a rebellious sub-tribe, the Tukuchi, which occurred in a huna 11. ah.
