What Is the Haab'? The Maya 365-Day Solar Calendar

The Haab' is the Maya 365-day civil / solar count: 18 named periods of 20 days plus a closing period of five days called Wayeb'. It runs alongside the 260-day Tzolk'in. This page explains that structure. It is not a Haab' calculator.

Quick answer. The Haab' is the Maya 365-day civil / solar count: 18 named periods of 20 days plus a closing period of five days called Wayeb'. It runs alongside the 260-day Tzolk'in (Chol Q'ij). Together they form longer cycles such as the Calendar Round. Unlike the Gregorian year, the classic Haab' description used in educational sources has no leap-day intercalation inside the 365-day count itself. [1][2][3]

Reviewed 30 October 2026 · This page is educational. Personal readings on this site use the traditional Tzolk'in with GMT correlation 584283 (gmt584283-proleptic-gregorian-v1). See methodology.

Haab' structure: 18 × 20 + Wayeb'

The Haab' year has 365 named positions:

PieceLengthRole
18 “months” (uinal / winal-style periods)20 days eachNamed periods such as Pop, Wo, Sip … through Kumk'u [1][2]
Wayeb'5 daysClosing period at the end of the Haab' year [1][2]
Total365One Haab' year

A full Haab' date pairs a day coefficient with a month name (for example, 14 Yax). Classic and colonial descriptions often treat the seating of a month as day 0 of that month—scholarship discusses “seating” vs numbered days carefully. [2] For this educational page, the key point is the 18 × 20 + 5 arithmetic, not a claim that every community writes coefficients the same way.

The eighteen Haab' periods (names at a glance)

Educational tables commonly list eighteen twenty-day periods with Yucatec names such as Pop, Wo, Sip, Sotz', Sek, Xul, Yaxk'in, Mol, Ch'en, Yax, Sak', Keh, Mak, K'ank'in, Muwan, Pax, K'ayab', Kumk'u, then Wayeb'. Spellings vary by orthography (colonial vs revised). [1][2] This site does not publish nineteen thin month landing pages in this content wave, and it does nottreat those names as Western-style zodiac personalities. If you need a personal reading today, stay with the Tzolk'in tools—not a guessed Haab' month from a fixed Gregorian date range (those fixed ranges drift because the classic Haab' count described here has no leap-day intercalation). [1][3]

What is Wayeb'?

Wayeb' is the five-dayclosing period of the Haab' year. Educational and ethnographic sources often describe it as a liminal or carefully observed stretch between solar years—not as a “Mayan zodiac sign” and not as a personality type in the way popular English sites sometimes misuse month names. [1] Practices and meanings vary by community and period. We are not daykeepers; we do not assign luck scores to Wayeb' births.

If you arrived here searching for “Pax,” “Sip,” “Mol,” or other month names as if they were your personal Mayan sign: those names belong to the Haab', not to the 20 day signs of the Tzolk'in that this site uses for birth readings. Your personal Nawal still comes from the 260-day count.

Haab' vs Tzolk'in vs Long Count (short)

SystemLengthWhat it tracks on this site
Tzolk'in / Chol Q'ij260 days (13 × 20)Primary. Your birth Nawal + number; today; free and paid readings
Haab'365 days (18 × 20 + 5)Educational only for now — no Haab' tool in the product UI
Long CountContinuous day countNot the focus of the consumer calculator
Calendar Round~52 vague years (18,980 days)Tzolk'in + Haab' pairing before the same combination repeats [1][2]

The Tzolk'in answers “which day name and number?” The Haab' answers “where are we in the solar / civil year of 365 named days?” They are complementary, not substitutes.

Year bearer (Mam / year lord) — teaser

A year bearer is the Tzolk'in day name associated with the start of a Haab' solar year—the day sign said to “carry” that year. Because 365 days shift against the 260-day count, only a small set of day names can serve as year bearers in a given tradition. Highland K'iche' practice commonly names four; later Yucatec lists often name a different four. Those systems must not be mixed as if they were identical. [4]

Dreamspell “13 Moon” is not the Haab'

Some modern sites call a 13 × 28 (+1) “13 Moon” year a Mayan solar calendar. Dreamspell / 13 Moon is a modern system (José and Lloydine Argüelles, from 1987; kit 1990). It is notthe classic Haab' of 18 × 20 + Wayeb'. [5][6] If another site tied your “New Year” to 26 July, that is a Dreamspell / 13 Moon convention—not proof that Pop always starts on that Gregorian date.

FAQ

How is Haab' different from the Tzolk'in?

The Haab' is a 365-day civil / solar count (18 × 20 + Wayeb'). The Tzolk'in is a 260-day sacred count (13 × 20). They run together; they measure different cycles. Personal readings on this site use the Tzolk'in. [1][2]

What is Wayeb'?

Wayeb' is the five-day closing period of the Haab' year. It is part of the solar count, not one of the 20 Tzolk'in day signs and not a Western-style zodiac sign. [1]

Does this site calculate my Haab' date today?

Not yet. This page explains the Haab'. The live calculators map Gregorian dates to the Tzolk'in (Nawal + tone) with GMT 584283. Use /today or /birth-chart for those results.

Are Pax, Sip, or Mol my “Mayan zodiac sign”?

Those names are Haab' month names in popular English lists—not the 20 Nawales used for birth signatures on this site. For a personal day sign, calculate your Tzolk'in combination.

Is the Dreamspell 13 Moon calendar the same as Haab'?

No. Dreamspell / 13 Moon is a modern calendar with a different year structure and count rules. See the Dreamspell comparison page. [5][6]

What is a year bearer?

The Tzolk'in day name associated with the start of a Haab' year in a given tradition. Details and the two common sets of four names: /year-bearer.
