What is the Aztec day sign for September 20, 2026?

It is 11-Ácatl in the Meza count, the 260-day divinatory cycle. The sign is Ácatl and the numeral 11. It falls in the trecena of 1-Calli. The veintena is Xócotl Huetzi. The year is 1-Tochtli.

Do all the counts agree on 11-Ácatl for September 20, 2026?

No. Meza gives 11-Ácatl; other correlations in circulation give 11-Cuauhtli, 7-Cipactli, 8-Ehécatl. There is no consensus on which one matches the Mexica calendar, so this site publishes all five with their sources rather than picking one and hiding the rest.

Which Lord of the Night rules September 20, 2026?

Cintéotl. The Lords of the Night are nine and follow each other in cycle, so Cintéotl returns every nine days.

What does it mean that 11-Ácatl falls in the trecena of 1-Calli?

A trecena is a run of thirteen days beginning with 1-Calli, and it lends its character to all thirteen. 11-Ácatl is one of them.

Which veintena does September 20, 2026 belong to?

Xócotl Huetzi. The veintenas are the eighteen twenty-day stretches of the Mexica solar year, each with its own feasts, and this is the one containing this date.

Alma Mexica: Quetzalcoatl, the feathered serpent, within the Mexica solar frame with the four eras.

11-Ácatl

According to the Meza count, the one the dance community follows. All five are below.

The day in the five counts

The Sun Stone in red and yellow: the face of Tonatiuh, the four eras, the twenty day-signs, the solar disc and the two Xiuhcoatl. — The **six rings of the Sun Stone**, each with the number of elements its entry declares: 52 sections in the Xiuhcóatl, 58 circles of night sky, 12 pictograms of the offering, 8 segments of jade and rays, the 20 day-signs and the 4 eras of the frame. Below, the day. The six, one by one.

The two hundred and sixty days of the count: twenty signs by thirteen numerals. In red, 11-Ácatl, in the Meza count. The trecena runs diagonally and wraps round, because thirteen and twenty do not divide: that is why it takes 260 days to repeat.

The year: eighteen veintenas of twenty days and the five nemontemi, drawn to scale. The five are not a short month: they are what is left of 365 after 360, and that is why they sit outside, hatched.

Caso y la GMT maya van juntas porque tienen el desplazamiento en cero: dan el mismo tonal todos los días, sin excepción. Las otras se separan por un desplazamiento fijo, así que su diferencia es la misma hoy y cualquier otro día.Ninguna es «la correcta». Esta obra no arbitra entre una tradición viva y una reconstrucción académica: publica las cinco con su ancla citada y sus fechas de control.
