The combination of signs and figures thus provided each day in the tonalamatl with an entirely distinct description. For example: the first day, cipactli, was in its first occurrence 1 cipactli; in its second 8 cipactli; in its third 2 cipactli; in its fourth 9 cipactli, and so on. No day in the tonalamatl was simply described as cipactli, coatl, or calli, and before its name was complete it was necessary to prefix to it one of the numbers from 1 to 13 as its incidence chanced to fall. Thus it was designated as ce cipactli (one crocodile) or ome coatl (two snake) as the case might be. Each of the 20 groups of 13 days (which are sometimes called “weeks”) was known as a division by the name of the first day of the group, as ce cipactli (one crocodile), ce ocelotl (one ocelot), ce mazatl (one deer), and so on. A model tonalamatl would thus have appeared as follows: Ce Cipactli (1) cipactli (2) eecatl (3) calli (4) cuetzpallin (5) coatl (6) miquiztli (7) mazatl (8) tochtli (9) atl (10) itzcuintli (11) ocomatli (12) malinalli (13) acatl. Ce Ocelotl (1) ocelotl (2) quauhtli (3) cozcaquauhtli (4) ollin (5) tecpatl (6) quiauitl (7) xochitl (8) cipactli (9) eecatl (10) calli (11) cuetzpallin (12) coatl (13) miquiztli Ce Mazatl (1) mazatl (2) tochtli (3) atl (4) itzcuintli (5) ocomatli (6) malinalli (7) acatl (8) ocelotl (9) quauhtli (10) cozcaquauhtli (11) ollin (12) tecpatl (13) quiauitl Ce Xochitl (1) xochitl (2) cipactli (3) eecatl (4) calli (5) cuetzpallin (6) coatl (7) miquiztli (8) mazatl (9) tochtli (10) atl (11) itzcuintli (12) ocomatli (13) malinalli Ce Acatl (1) acatl (2) ocelotl (3) quauhtli (4) cozcaquauhtli (5) ollin (6) tecpatl (7) quiauitl (8) xochitl (9) cipactli (10) eecatl (11) calli (12) cuetzpallin (13) coatl Ce Miquiztli (1) miquiztli (2) mazatl (3) tochtli (4) atl (5) itzcuintli (6) ocomatli (7) malinalli (8) acatl (9) ocelotl (10) quauhtli (11) cozcaquauhtli (12) ollin (13) tecpatl
