Mayan Calendar · Number 4 of 13

Four, the number of the eras' first and last day

Number 4 is the fourth of the thirteen numbers of the 260-day count, written as four dots. It begins EsoTerrier's middle band, and it numbers the most famous day in the count: 4 Ajaw, which opens the current era of the Long Count and closed its thirteenth b'ak'tun in 2012.

Meaning

Four is the first of the numbers we place in our middle band, 4 to 9. The band is our grouping of the principle, reported from the highland ethnography, that the low numbers are gentle and the high ones strong; it is not a published scheme.

Our sentence for four is that it is the number of the directions and the corners of the field, steady and dependable; with the keyword "foundation, the four directions" it is EsoTerrier's own aid, not the tradition's teaching.

Days and ceremonies

The Long Count begins on 4 Ajaw 8 Kumk'u, 11 August 3114 BCE in the proleptic Gregorian calendar, and its thirteenth b'ak'tun closed on another 4 Ajaw, 4 Ajaw 3 K'ank'in, 21 December 2012, when the fourteenth began. Nothing ended: the count went on, as the daykeepers' did.

4 Kej bore the highland year of 1990, and 4 Iq' bears the one that opens in February 2029, by the rule that the bearer's number rises by one each year.

The numeral

Four dots. Thompson identified the Classic head for 4 as the aged sun god, the god of the day Ajaw: a fitting pair for the day 4 Ajaw, though the head belongs to Classic writing, not to the living count.

In the count

The number 4 falls on twenty days of the 260: days 4, 17, 30, 43, 56, 69, 82, 95, 108, 121, 134, 147, 160, 173, 186, 199, 212, 225, 238 and 251, with the signs K'at, No'j, Tz'i', Aq'ab'al, Ajmaq, Toj, Iq', Tz'ikin, Q'anil, Imox, I'x, Kej, Ajpu, Aj, Kame, Kawoq, E, Kan, Tijax and B'atz' in that order. A sign comes back every twenty days and a number every thirteen, so the same pairing, such as 4 K'at, 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.
