Mayan Calendar · Day sign 17 of 20

No'j, thought, wisdom and good counsel

No'j is the seventeenth day sign of the 260-day count: No'j in K'iche', thought and wisdom, and Kab'an in Yucatec, the earth. It is one of the four days that bear a highland year, and the Western habit of calling it the earthquake comes from the Aztec day of the same position.

Meaning

The Yucatec and Classic word is earth: kab'an, with the Classic reading chab or kab. Thompson read the glyph as a lock of the earth goddess's hair and gave the day to the youthful earth and moon goddess, matching the head that writes the number 1.

The highland name No'j means thought and wisdom, and the daykeepers read it so: the Komon Tohil daykeepers make it the day to join ideas, give advice and cultivate knowledge, and the Maya' Wuj manual the day of decisions and of council.

Our reading: thought, knowledge and good counsel. People born on No'j are described as thoughtful and wise in advice. The words are ours.

In the highlands today

In Momostenango the day is simply wisdom, the one who knows. Maya' Wuj adds that it was the day the grandmothers and grandfathers gave thanks for their wisdom.

No'j is one of the four highland year bearers. 8 No'j entered on 20 February 2020; the 2022 account in Prensa Comunitaria places No'j in the east, red, where the sun is born.

The glyph and the old readings

Kab'an was also one of the Classic year bearers. Thompson's Yucatec augury for the day is the woodpecker, his highland one the earth.

The Central Mexican day of the same position is Olin, movement or earthquake, which is why Western pages call this day the earthquake: that is the Central Mexican image, not the K'iche' one.

In the count

No'j comes round every twentieth day, thirteen times in the 260: on days 17, 37, 57, 77, 97, 117, 137, 157, 177, 197, 217, 237 and 257, with the numbers 4, 11, 5, 12, 6, 13, 7, 1, 8, 2, 9, 3 and 10 in that order, so 4 No'j is its first day in the count and 10 No'j its last. In the nawal cross of a person born on No'j, the day eight before (conception) falls on Toj, the day eight after (destiny) on Kan, six before (the right hand) on B'atz' and six after (the left hand) on Aq'ab'al, each with its own number.

How the schools read it

Classic inscriptions (epigraphers)
Reading of the glyph: Chab? or Kab?
J. Eric S. Thompson, 1950
The glyph as lock of the earth goddess's hair; the day's god the youthful earth and moon goddess.
Komon Tohil daykeepers, Zunil
Wisdom, criterion, reason, thought.
The Maya' Wuj manual
Knowledge and wisdom; the day the grandmothers and grandfathers gave thanks for their wisdom; a day for decisions and for holding council.
Momostenango (Andrés Xiloj, 2005)
Wisdom; the wise person, the one who knows.
The Central Mexican count (tonalpohualli)
Olin, movement, earthquake: the day of the same position in a related but different count.
Dreamspell (1990)
"Red Earth" for the same position in its own count; not our name for the sign.
EsoTerrier
Thought, knowledge and good counsel: thoughtful, and wise in advice. Our words.

Claims about it

  • No'j is the earthquake.

    false

    What the record shows: Olin, movement or earthquake, is the Central Mexican day. The K'iche' name means thought, and the Yucatec the earth.

  • No'j bears the same years in every calendar.

    disputed

    What the record shows: It bears years in the highland and Classic sets, the Classic number one higher; Landa's Yucatan used other bearers.

  • No'j is the "Red Earth".

    false

    What the record shows: That is a Dreamspell name from a modern count of 1990.
