Part 10 (1/2)
Thus every day in the year is so distinguished that it can never be confounded with any other. The day 4 Ollin is the 17th day of both the first and the fourteenth month; but in the first instance it is distinguished by the letter _h_, and in the second by the letter _g_. If the characteristics of the 9th day of the 10th month be required, the Table shows that it is 7 _Atl i_; and thus also the 13th day of the 16th month (Quecholli) is shown to be 1 _Acatl g_, and the 313th of the year.
But it is only for the first year of the cycle (1 Tochtli) that the Mexican year corresponds with ours in the manner stated in the Table. For, on account of our intercalation of one day every biss.e.xtile year, the Mexican year receded, as compared with ours, one day every four years. This correction must therefore be made, whenever a comparison of the dates is wanted for any other than the first year of the cycle. The Mexican intercalation of 13 days at the end of the cycle of 52 years made again the first year of every cycle correspond with our year, in the manner stated in the Table.
Another correction is again necessary, when we have a Tescocan instead of a Mexican date. For the first year of the Mexican cycle was 1 Tochtli, and that of Tescoco was 1 Acatl; which caused a difference now of three, now of ten days in their calendars, which in every other respect were the same. Both corrections appear in the second Table.--Trans. Amer. Ethnol. Soc., vol. i, p. 114.
