The eighteen veintenas
The eighteen twenty-day stretches of the Mexica solar year. Eighteen of them make 360 days; five more — the nemontemi — close the 365.
How this is made
Each entry gives what the veintena is, what it asks of you, its rites, its symbolism and its ecology. Etymology, society and the codices rest on sixteenth-century quotations and stay in Spanish.
