The Maya Calendar – Part 2 – Haab, the Solar Year

This post “The Maya Calendar” is an excerpt of the second edition of my book “The Maya Sites – Hidden Treasures of the Rain Forest”, a travel guide to the most important Maya sites on the Yucatán peninsula – in México and Guatemala. The second edition will be published as print and ebook in spring 2018.

I split this article into seven parts:

Haab – a Calendar for the Solar Year

The calendar closest to our solar calendar is the “Haab” calendar. The word in Yucatecan Maya, the Mayathan, simply means year. This calendar, like our Gregorian calendar, is aligned with the solar year and lasts 365 days.

The original purpose of the Haab calendar was to predict or incorporate the recurrent events that were important in the life of the Maya. Sowing and harvesting, dry or rainy seasons or even dates for the beginning of the hunting season or the collection of honey were indicated by the Haab calendar.

In his book, Diego De Landa describes numerous ceremonies, rituals, and festivals, which were performed in the various periods by the Maya under the guidance of their priests.

The Haab calendar is divided into months similar to our calendar. These months are called Uinal or Winal in Mayathan. Each Uinal period has a duration of 20 days.

That’s why you need 18 Uinal to fill up the year. As a result, you get 360 days.

The remaining 5 days are called Wayab, the nameless days, and finally added as a separate period. Thus the 365 days of the solar year are complete.

The ancient Maya used a special hieroglyphic symbol or sign for each month.  The tables below show the months in their order, with the symbols used and a few notes from the records made by Diego De Landa for each month.

Haab-Kalender - Monate 0 bis 4 - Pop, Uo, Zip, Zotz, Tzec

Haab-Kalender – Monate 0 bis 4 – Pop, Uo, Zip, Zotz, Tzec

Haab - Monate 9 -12 - Yax, Zak, Keh, Mac

Haab – Monate 9 -12 – Yax, Zak, Keh, Mac

Haab - Monate 13 - 16 Kankin, Muwan, Pax, Kayab

Haab – Monate 13 – 16 Kankin, Muwan, Pax, Kayab

Haab - Monate 17 & 18 - Kumku, Wayeb

Haab – Monate 17 & 18 – Kumku, Wayeb


The individual 20 days of the month have no names but are numbered from 0 to 19.

7 Pop or 14 Zip are therefore certain days in the Mayan calendar, such as August 1st or December 24th for us. The Mayathan word for  “day” is Kin.

The Maya year in the Haab calendar starts with the date 0 pop. According to the records of Diego de Landa, this was always on July 16 (Julian) or on July 26 (Gregorian). Remind, that at the time of Diego de Landa the Julian calendar was still in use.

But, at this point, Diego de Landa may be wrong. According to his report, the Maya used a calendar correction, which he calls a leap year. An additional day was inserted every 4 years according to our leap year.

Leap Year?

Due to this hypothetic additional day in a leap year, the Maya year on the Haab calendar would actually have started on the same day every year.

However, the content of this statement is called into question by modern Maya researchers because it would not explain the synchronization of the various calendars, as used in the inscriptions.

The actual opinion of the Mayanists is that the Maya used no leap year, at least not during the period in which the inscriptions were created.

The lack of a leap year would have shifted the beginning of the Maya year every four years by one day.

So it remains a mystery. The Maya may have had reformed their calendar at the time Diego de Landa noted his findings, as it was the case with the switch from the Julian to the Gregorian calendar system in Europe.

After all, between the time of the last classic inscriptions and the conquest by the Spaniards more than 600 years had passed, a time about which we are only sparsely informed.
