2. That it was composed of 20 day-signs, repeated 13 times, or 260 day-signs in all.
3. That these were usually divided into 20 groups of 13 days each, erroneously but usefully called “weeks.” The initial days of these “weeks” gave the name to the entire “week.”
4. To effect this division the numbers 1 to 13 were added to the 20 day-signs in continuous series.
5. That by this arrangement each day-sign had a number that did not recur in connection with that sign for a space of 260 days.
6. That the name of a day-sign in the tonalamatl was not complete without its accompanying number.
7. Each of the day-signs of the tonalamatl was presided over by a god who was supposed to exercise a special influence over it. (See list.)
Each of the 20 tonalamatl divisions or “weeks” had also a patron god of its own. (See list.)
8. Besides the patron gods of the days and “weeks” there were:
- (a) Nine “lords” or patron gods of the night-hours.
- (b) Thirteen “lords” of the day-hours.
