Maya Kin Calculator (Tzolk'in)
Enter a date to calculate your Kin number (1–260), tone, and day sign based on the traditional GMT correlation.
What Is a Kin in the Maya Calendar?
In the 260-day Tzolk'in cycle, each day is identified by a unique combination of:
- Tone (1 to 13)
- Day Sign / Seal (1 to 20)
That unique combination is commonly called a Kin. Because 13 and 20 cycle together, there are exactly 260 unique Kin signatures before the pattern repeats.
How to Use This Kin Maya Calculator
Step-by-step
- Select your birth date (or any date you want to explore).
- Click Calculate Kin.
- Read your Kin number, tone, and seal in the result panel.
The calculator is useful for birthday readings, daily spiritual reflection, and comparing different dates in the Mayan sacred calendar.
How the Calculation Works
This page uses a standard Julian Day Number conversion and the widely used GMT correlation constant (584283). From there, the algorithm maps the date into the 260-day Tzolk'in cycle.
- Convert Gregorian date to Julian Day Number.
- Shift by correlation so the cycle aligns historically.
- Reduce modulo 260 to get Kin number.
- Derive tone (mod 13) and seal (mod 20).
Note: Different schools (traditional epigraphy, Dreamspell, local lineages) may use different systems. If your result differs from another site, it is often due to correlation method or leap-day handling.
Interpreting Your Result
Tone Meaning
The tone describes how energy moves (initiation, balance, transformation, completion, etc.).
Seal Meaning
The seal describes what archetypal quality is emphasized (such as Dragon, Wind, Night, Sun).
Color Cycle
Colors follow a repeating pattern: Red, White, Blue, Yellow. Many practitioners interpret these as initiation, refinement, transformation, and ripening.
