Tzolk'in Calculator
Enter your birthday in this Tzolk'in calculator. People also spell it Tzolkin. The Mayan Tzolk'in (Maya 260-day calendar) combines 20 day-signs (nawales) with 13 tones. Your birthday gives you one pair. This is cultural storytelling, not a copy of the Western zodiac.
Use this page when you want the Mayan side explained in plain language. We spell out both the day-sign and the tone.
Example: one real birth date
The Mayan calculator returns 13 Men (Eagle) for September 7, 2023.
The day-sign and tone change every day. They do not follow a sun-sign month.
How we calculate
Mayan day-sign uses a simplified Tzolk'in (Maya 260-day calendar) count. Your birth date gives you one of twenty nawales plus a tone from 1 to 13.
This matches our Mayan card on the home reader. Living Maya communities may count days differently.
- Input: birth date only
- Calendar: 260-day Tzolk'in (20 × 13) day-count
- Output: tone, nawal name, and short description
Day-sign and tone together
The nawal names a story quality: road, serpent, wind, and so on. The tone (1 to 13) shapes how that quality moves through a day or a life in traditional teaching.
Frequently asked questions
Is this the same as Aztec or other Mesoamerican calendars?
We use a simplified Tzolk'in day-count aligned with our in-app Mayan tradition. It is for cultural comparison, not archaeological proof.
Do I need birth time?
No. The day-sign here uses your birthdate only.
