Tozoztontli
«The small vigil»

What a veintena is
One of the eighteen twenty-day stretches of the Mexica solar year. Eighteen of them make 360 days; five more — the nemontemi — close the 365. This is a different count from the 260-day one that gives the day-signs, and the two run at the same time.
What this one asks of you
To watch over what is barely sprouting, without hurrying it or celebrating it too soon.
The energy it is dedicated to is Tláloc.
The full entry is in Spanish, and here is why
What you have read above is this project's own summary of the veintena of Tozoztontli. The full entry — the part that rests on the sixteenth-century sources — has not been translated, and that is a decision rather than an omission.
We chose not to touch the primary text. Those sections quote Sahagún, Durán and the codices in their own words, often in sixteenth-century Castilian. A quotation carried across stops being a quotation: it loses the register, the ambiguity and the exact wording someone might want to check against a facsimile.
In Spanish the entry carries:
- Etimología
- Energías
- Rituales
- Sociedad
- Simbolismo
- Códices
- Ecología
- Vigencia hoy
- Interpretaciones modernas

Ecology
The season
In qualitative terms this is the time of preparing for the rains: the maize is jointing under irrigation and the rain is asked for, but has not yet come. What is called for is watching and sustaining, not harvesting.
Symbolism
Renewal by letting go
The heart of the veintena is an idea, not a rite: the skin that is worn and then released. The new does not appear because something is added, but because something is let go.
Rituals
Here a rite that spans two veintenas closes: those who had worn the skins since Tlacaxipehualiztli let them go after twenty days and laid them away. The act itself does not take place here; its meaning, though, is the core of this veintena and is stated in full: renewal by letting go. It is not the one who accumulates who is renewed, but the one who releases what has already dried.
The first flowers of the season were offered to Coatlicue. The rule was plain: no flower could be smelled or used before being offered. First fruits — the first of everything — go to the sacred before they go to us.
The lesser vigil: sustained attention on the maize barely showing and on everything still fragile. It is not a time to celebrate a harvest that does not exist, but to accompany what is beginning.
