Tzolk'in (from the revised Guatemala Mayan languages Academy orthography, which is preferred by the linguists of the Summer Institute of Linguistics, formerly and commonly tzolkin) is the name bestowed by Mayanists on the 260-day Mesoamerican calendar used by the Maya civilization of pre-Columbian Mesoamerica.
The tzolk'in, the basic cycle of the Maya calendar, is a pre-eminent component in the society and rituals of the ancient and the modern Maya. The tzolk'in is still in use by several Maya communities in the Guatemalan highlands. Its use is marginal but spreading in this region, although opposition from Evangelical Christian converts continues in some communities.
The word, meaning "division of days", is a western invention coined in Yukatek Maya. The corresponding words used by the K'iche' and Kaqchikel peoples of Guatemala, which have maintained an unbroken count for over 500 years, are, respectively, Aj Ilabal Q’ij 'the sense of the day' and Chol Q'ij, 'the organization of time'. The actual names of this calendar as used by the pre-Columbian Maya are not widely known. The corresponding Postclassic Aztec calendar, was called tonalpohualli, in the Nahuatl language.
The Twenty Day Names
The tzolk'in calendar combines a cycle of twenty named days with another cycle of thirteen numbers (the trecena), to produce 260 unique days (i.e., 20 × 13 = 260). Each successive named day was numbered from 1 up to 13 and then starting again at 1. There were 20 individual named days, as shown in the table below:

1. the sequence number of the named day in the Tzolk'in calendar
2. Day name, in the standardized and revised orthography of the Guatemalan Academia de Lenguas Mayas
3. An example glyph (logogram) for the named day, typical of monumental inscriptions ("cartouche" version). Note that for most of these several alternate forms also exist.
4. Example glyph, Maya codex style. When drawn or painted, most often a more economical style was employed; the meaning is the same. Again, variations to codex-style glyphs also exist.
5. Day name, as recorded from 16th century Yucatec language accounts, according to Diego de Landa; this orthography has (until recently) been widely used
6. In most cases, the actual day name as spoken in the time of the Classic Period (c. 200-900) when most inscriptions were made is not known. The versions given here (in Classical Maya, the main language of the inscriptions) are reconstructed based on phonological comparisons; a '?' symbol indicates the reconstruction is tentative.
7. Each named day had a common association or identification with particular natural phenomena
The Tzolkin does not have a generally-recognized start and end, although there are specific references in the books of Chilam Balam to 1 Imix as the beginning day.
Each of the twenty days has its specific primary association connected to the day name's meaning.
- Imix : 'Crocodile' - the reptilian body of the planet earth, or world
- Ik : 'Wind' - breath, life. Also violence.
- Akbal : 'Night-house' - darkness, the underworld, realm of the nocturnal jaguar-sun.
- Kan : 'Maize' - sign of the young maize lord who brings abundance, ripeness. Also lizard, net.
- Chicchan : 'Snake' - the celestial serpent
- Cimi : 'Death'
- Manik : 'Deer' - sign of the Lord of the Hunt
- Lamat : 'Rabbit' - sign of the planet Venus, sunset. The glyph may depict four grains of maize. Invoked by the feminine name "Ixq'anil" by Xquic.
- Muluc : 'Water' - symbolised by jade, an aspect of the water deities, fish. Invoked by the feminine name "Ixtoj" by Xquic.
- Oc : 'Dog' - who guides the night sun through the underworld.
- Chuen : 'Monkey' - the great craftsman, patron of arts and knowledge. Also thread.
- Eb : 'Grass' or 'Point' - associated with rain and storms.
- Ben : 'Reed' - who fosters the growth of corn, cane, and man.
- Ix : 'Jaguar' - the night sun. Also maize. Associated with the goddess Ixchel.
- Men : 'Eagle' - the wise one, bird, moon
- Cib : 'Owl/Vulture' - death-birds of night and day. Also wax, soul, insect.
- Caban : 'Earthquake' - formidable power. Also season, thought.
- Etz'nab : 'Knife' - the obsidian sacrificial blade.
- Cauac : 'Rain' or 'Storm' - the celestial dragon serpents and the chacs, gods of thunder and lightning.
- Ahau : 'Lord' - the radiant sun god. Also associated with the Mayan hero twins.
The Tzolk'in was extensively used in Mayan inscriptions and codices. Symbolism related to the Tzolk'in is also observed in the Popol Vuh (which, though written in the early post-conquest period, is probably based on older texts). For instance, when Ixbalanque has set an impossible task for Ix Quic of collecting a netful of corn from one stalk and Ix Quic successfully completes it, she leaves the imprint of her net in the ground, and the day "net" is the opening of the Venus cycle which follows "ahau" ("ajpu" in K'iche'), just as her child is the heir of Hun Hunajpu.
The uses to which the ancient Maya applied the calendar are unknown, nonetheless modern Maya communities employ the calendar as follows:
- For Maize cultivation.(The zenith transit days may have been significant for agriculture along the south coast of Guatemala because April 30 occurs just before the rainy season. Modern Maya plant their corn at the end of April or early in May. In the August 13 zenith transit the Maya initiate its current era in this day', approximating the harvest of the dried corn.
- For modern Guatemalan highlanders, the 260 days are employed in training the Aj K'ij, or 'calendar diviner'. Nine months after commencing training in divination, the novice is "reborn" and initiated into office. The tzolk'in is explainable, in principle, as a calendar of midwives, since it counts 260 days from the 20 day period of the conception, from when the heart of the fetus starts to beat, until birth.
- For rituals performed every 260 days. Most famous of these is the "Initiation" celebration of 8 Chuwen, Waxakib' B'atz, in the K'iche town of Santa Cruz del Quiche.
- For days which are suitable for certain actions. For instance, a low-numbered Ak'ab'al or B'en would be a good day for a wedding, whereas K'an would be a good day for building or maintaining a house.
- For divination based on casting lots and counting forward through the calendar from the current 'year bearer' to arrive at a day which is then interpreted. This is not pure cleromancy because somatic twitches of "blood lightning" can either be specifically consulted or arise spontaneously during the process.
- For traditional Mayan names, which are based on calendar days, often birthdays. As in astrology, personal characteristics are associated with birthdays (see Mayan astrology for details).
The 260-day calendar spread throughout the Mesoamerican cultural region, and it is regarded as being the oldest and most important of the calendar systems attested in the region, with an origin pre-dating its first appearances in Maya inscriptions. It is uncertain which Mesoamerican culture first developed this calendar. Stelae with the earliest known Long Count dates come from this general area. Some of the oldest calendric inscriptions are from early strata of Zapotec in the Oaxacan highlands at sites such as Monte Albán, dating from mid 1st-millennium BCE. A few earlier-dated inscriptions and artifacts have what appear to be calendric glyphs, such as at San José Mogote and in the Olmec Gulf Coast region. However, either the dating method or the calendric nature of the glyphs are disputed by scholars.
The original purpose of such a calendar, with no obvious relation to any astronomical or geophysical cycle, is not securely known, but there are several theories. One theory is that the calendar came from mathematical operations based on the numbers thirteen and twenty, which were important numbers to the Maya, (Thompson 1950: An Introduction to Maya Hieroglyphic Writing). The number twenty was the basis of the Maya counting system, taken from the total number of human digits. (See Maya numerals). Thirteen symbolized the number of levels in the Upperworld where the gods lived, and is also cited by modern daykeepers as the number of "joints" in the human body (ankles, knees, hips, shoulders, elbows, wrists, and neck). The numbers multiplied together equal 260.
Barbara Tedlock, studied this system in the contemporary K'iche Maya community of the municipality of Momostenango in highland Guatemala. She underwent a formal apprenticeship in calendar divination with a local adept, and was initiated as a diviner in 1976. She says: "The Momostecan calendar embraces both the 260-day cycle and the 365-day solar year, with the four Classic Maya Year-bearers, or Mam, systematically linking the two. The 260-day cycle is conceived as linked firmly to worldly or earthly affairs, mirroring no astronomical period but rather the period of human gestation. Past ethnographic accounts of this cycle contain various conflicting opinions as to what its first day is, but a comparison of the present results and those of previous studies indicates that there is no fixed first day."
Anthony Aveni seerts, "Once a Maya genius may have recognized that somewhere deep within the calendar system lay the miraculous union, the magical crossing point of a host of time cycles: 9 moons, 13 times 20, a birth cycle, a planting cycle, a Venus cycle, a sun cycle, an eclipse cycle. The number 260 was tailor made for the Maya". Others have observed that the "Venus Table" in the Dresden Codex, is an accurate ephemeris for predicting Venus positions. Others have also observed a basis for the 260 day cycle in the agricultural cycle of highland Guatemala, which is also about 260 days. There may also be a relation to the average length of time it takes between appearances of the planet Venus as morning or evening star, which is in round numbers 263 days. Aveni notes that "the average duration between successive halves of the eclipse season, at 173 ½ days, fits into the tzolkin in the ratio of 3 to 2." This may seem contrived, but the Maya did employ the tzolkin to predict positions of Venus and eclipses.
Another theory is that the 260-day period is the length of human pregnancy. This is close to the average number of days between the first missed menstrual period and birth, unlike Naegele's rule which is 40 weeks (280 days) between the last menstrual period and birth. It is postulated that midwives originally developed the calendar to predict babies' expected birth dates.
Vincent Malmström identifies a correlation between the 260-day cycle and the 260-day gap between zenith and transits of the sun. According to this hypothesis, the 260-day cycle originated in the narrow latitudinal band (14º42'N to 15ºN) in which the sun is vertically overhead about 12–13 August and again 260 days later about 30 April-l May (Malmström identifies the proto-Classic Izapan culture as one suitable candidate at this latitude). This period may have been used for the planting schedule of maize. However, others object to this conception, noting that while the 260-day calendar runs continuously the interval between autumn-spring and spring-autumn positions alternates between 260 and 105 days, and that the earliest-known calendric inscriptions are from considerably further north of this zone. Consequently this theory is not widely supported.
It is of course also possible that the number 260 has multiple sources.
The Tzolk'in and the New Age Movement
The Tzolk'in is the basis for the modern, New Age invention of the "Dreamspell" calendar, developed by the esoteric author Jose Arguelles. The Dreamspell calendar is sometimes mistakenly identified as an authentic interpretation or extension of the original Maya calendar, although Arguelles himself acknowledges the Dreamspell calendar is a new and syncretic creation, inspired by elements from mesoamerican and non-mesoamerican sources.
In 1987, before the Harmonic Convergence, inspired by a single paragraph of Dr. Arguelles book "The Mayan Factor" (wherein he refers to each day as a "tone"), singer/songwriter and sound healer, Alyras (aka Mirai), translated the Tzolk'in's harmonic values into sound, with the tutelage of Barbara Hero.Eschewing extensions of the Tzolk'in, Alyras opted for strict mathematical adherence to the Tzolk'in's fundamental structure and sequences, in order to present a truly authentic sonic expression of its inner workings. (See "Ascension: The Tzolk'in Series" and "The Radiant Tzolk'in" for both audio and audiovisual expressions of the Tzolk'in, respectively).
