The three calendars
Most cultures had one calendar. The Maya kept three running simultaneously — each measuring something different, all interlocking. A given day is a co-ordinate in three systems at once. The Maya did not measure time. They located themselves inside it.
The sacred count
The oldest known calendar cycle in Mesoamerica, dating to at least 600 BCE. 20 day-signs × 13 numbers = 260 unique days. The length matches the human gestation period and nine cycles of the moon. Used for divination, ritual timing, and naming children. A daykeeper still consults it.
The solar count
18 named months of 20 days each, plus a 5-day shadow period called Wayeb'. Tracked agricultural cycles, seasonal festivals, the planting and harvest. The Wayeb' days were considered dangerous — the veil between worlds thin, the calendar briefly empty.
The world-age count
Days counted since the mythical creation event on 11 August 3114 BCE. Five-place positional system: kin · uinal · tun · katun · baktun. The current creation cycle (the 13th baktun) completed on 21 Dec 2012. We are inside the next cycle now.
A given day is a coordinate in three systems at once. The Maya did not measure time. They located themselves inside it.
The Tzolk'in · 20 day-signs
Each day belongs to a day-sign with its own character, animal, and direction. Walked in order, 1 through 20, paired with a number that cycles 1 through 13. The two cycles tick independently — it takes 260 days before the same combination returns.
The Haab' · 18 months + Wayeb'
Eighteen months of 20 days, plus a final 5-day Wayeb'. Each Haab' month had a name and a patron deity. The Wayeb' was a liminal time — fasting, no ceremonies, the world unguarded.
The Long Count
The Long Count is a five-place positional system, written like 13.0.0.0.0. Each place has its own unit:
| Unit | Equals | Roughly |
|---|---|---|
| K'in | 1 day | day |
| Winal | 20 k'in | ~ 3 weeks |
| Tun | 18 winal · 360 days | ~ year |
| K'atun | 20 tun · 7,200 days | ~ 20 years |
| B'ak'tun | 20 k'atun · 144,000 days | ~ 394 years |
Day zero was 11 August 3114 BCE. The completion of the 13th b'ak'tun — 13.0.0.0.0 — fell on 21 December 2012. Contrary to the popular myth, the Maya did not say the world would end. They said one creation cycle ends and another begins. The current count restarted from 13.0.0.0.1 and runs forward from there.
The Calendar Round
Combine a Tzolk'in date with a Haab' date and you get a unique pairing that recurs only every 18,980 days — approximately 52 solar years. A full human life inside one round. The Maya marked the completion of each round with the New Fire ceremony — every household extinguished its hearth, and a single sacred fire was kindled from which every other was relit. The world made new.
A full human life inside one round. The world made new at the end.
How to use this
As mirror. Read your birth Tzolk'in date as a portrait. The number is your tone (intensity, frequency). The day-sign is your archetype. Both colour the day you arrived.
As compass. The 260-day cycle has been used continuously by Maya daykeepers in the Guatemalan highlands for over two millennia. The Tzolk'in date today still informs what kind of work, ritual, or conversation belongs to it.
As reminder. We're inside b'ak'tun 14, the first century of a new world-age. The Maya recorded the previous turning. We're recording the current one — whether we mean to or not.
