But more recently ZuidemaR.T., “A quipu calendar from Ica, Peru, with a comparison to the ceque calendar from Cuzco”, World archaeoastronomy, ed. by AveniA. (Cambridge, 1989), 341–51, has offered two such possible examples.

Zuidema on the other hand sees the calendar as a single coherent system. See ZuidemaR.T., “The Inca calendar”, Native American astronomy, ed. by AveniA. (Austin, Texas, 1977), 219–59.

Intercalating a thirteenth month every three years would result in a difference of 4.25 days between an integral number of synodic months and tropical years; this could not have been satisfactory for too long. On the other hand, the Inca empire did not last a lengthy enough period to develop such a putative scheme.

See ZuidemaR.T.,“Catachillay: The role of the Pleiades and of the Southern Cross and Alpha and Beta Centauri in the calendar of the Incas”, Ethnoastronomy and archaeoastronomy in the American tropics, ed. by AveniA.F.UrtonG. (Annals of the New York Academy of Sciences, ccclxxxv; New York, 1982), 203–29, for an explanation of the reasons. This is certainly not done to escape from the trap of a temporal “no man's land” (Ziolkowski, p. 205) and it is by no means a “needless addition” (Sadowski, p. 210) to the calendar, as the references in Aveni, Empires of time, will testify.
