Mayan Calendar · Number 1 of 13

One, the number that opens every run of thirteen

Number 1 is the first of the thirteen numbers of the 260-day count, written as a single dot. Every thirteen-day run begins with it, 1 Imox is the first day of the 260, and in the highland reading reported from Momostenango it belongs to the gentle low numbers.

Meaning

Every day of the count carries a number beside its sign, and a daykeeper reads the pair together. One opens each thirteen-day run: after 13 comes 1 again, with the next sign. In the highland ethnography, as others report Barbara Tedlock's work at Momostenango and Ruth Bunzel's at Chichicastenango, the low numbers are gentle and the high ones strong.

We place 1 in our mild band, with 2 and 3; the bands and their edges are EsoTerrier's grouping of that reported principle, not a published scheme. Our keyword for it, "beginning, seed", and our sentence, that one is a mild, unformed force, the first step of whatever is starting, are ours, offered as a reading aid and not as what the tradition teaches.

Days and ceremonies

1 Imox is day 1 of the 260, the day the count's tables begin with. 1 Kej opened the highland year on 18 February 2026, the bearer whose number then rises by one each year.

Barbara Tedlock described in her 2005 interview how daykeepers take people to the shrines especially on days numbered one, for prayers and ceremonies there.

The numeral

The scribes wrote one as a single dot. In the Classic inscriptions a number could also be written as the head of a god, and Thompson identified the head for 1 as the youthful earth and moon goddess, the same god he gave to the day Kab'an: a Classic writing fact, which says nothing about how a daykeeper reads the number today.

In the count

The number 1 falls on twenty days of the 260: days 1, 14, 27, 40, 53, 66, 79, 92, 105, 118, 131, 144, 157, 170, 183, 196, 209, 222, 235 and 248, with the signs Imox, I'x, Kej, Ajpu, Aj, Kame, Kawoq, E, Kan, Tijax, B'atz', K'at, No'j, Tz'i', Aq'ab'al, Ajmaq, Toj, Iq', Tz'ikin and Q'anil in that order. A sign comes back every twenty days and a number every thirteen, so the same pairing, such as 1 Imox, returns only after 260 days. Each year the highland year bearer's number rises by one, because 365 days are 28 runs of thirteen and one day more.

How the schools read it

Highland ethnography, as reported
The number is the strength of the day, gentle in the low numbers and strong in the high.
Thompson's survey of highland towns
Which numbers count as good or bad differs from town to town.
Classic scribes
Wrote 1 as one dot, or as a god's head: the youthful earth and moon goddess, in Thompson's identification.
Dreamspell (1990)
Gives each number a name of its own in a different modern count; not used here.
EsoTerrier
Mild in our bands; keyword "beginning, seed". Our words, a reading aid.

Claims about it

  • The number 1 has a fixed traditional character.

    unverified

    What the record shows: The highland reports give the numbers strength, low gentle and high strong; fixed characters per number are modern, and our own keyword is labelled as ours.

  • One is one of thirteen cosmic "tones" with a Maya name.

    false

    What the record shows: The tone names are Dreamspell's, from 1990. The Maya count has numbers 1 to 13.
