Calculate Your Mayan Kin
Enter any Gregorian date to calculate the Tzolk'in kin number, tone, and day sign.
Method: Traditional Tzolk'in count using GMT correlation (JDN 584283).
What Is a Mayan Kin?
In the Mayan Tzolk'in calendar, every day is identified by a unique combination of a number (1–13) and a day sign (1–20). These combinations cycle together to create 260 unique day energies, often called kin. A kin can be used as a symbolic lens for reflection, personality exploration, intention setting, and ritual timing.
If you've ever seen terms like “Kin 160,” “Tone 4,” or “Ajaw,” this calculator gives you those exact markers from a selected date. It is useful for birthdays, anniversaries, project launch dates, and spiritual calendar study.
How This Calculator Works
This page converts a Gregorian date into a Julian Day Number (JDN), then maps that number onto the 260-day Tzolk'in cycle. The mapping here is based on the widely used GMT correlation constant of 584283, where the Long Count epoch is aligned to the Gregorian calendar.
- Kin Number: Position in the 260-day sequence (1 to 260)
- Tone: One of 13 galactic tones (numerical pulse of the day)
- Day Sign: One of 20 sacred day symbols in repeating order
- Color Family: Red, White, Blue, or Yellow cycle associated with sign sequence
Understanding Your Result
1) Kin Number
The kin number helps place your date into the full Tzolk'in matrix. People often track personal patterns by comparing kin across key life events, relationships, and yearly cycles.
2) Tone (1–13)
The tone describes the day’s movement or energetic style. For example, Tone 1 is often associated with initiation, while Tone 13 is associated with completion and transcendence.
3) Day Sign (1–20)
The day sign represents archetypal qualities such as vision, communication, vitality, transformation, and wisdom. Traditional names like Imix, Ik', Ak'b'al, K'an, Ajaw are included in the calculation output.

Frequently Asked Questions
Why might another website give me a different kin?
Some websites use alternate correlations or modern adaptations (such as Dreamspell conventions). Even a one-day offset can change your tone and sign. This calculator clearly states its method so your results remain consistent.
Can I calculate past and future dates?
Yes. As long as your date can be represented in the Gregorian calendar, the calculator will map it into the 260-day cycle.
Is this for spiritual or historical use?
Both. You can use it as a practical date-conversion tool or as a personal reflection framework. Always approach Indigenous calendar systems with respect for their cultural depth and living traditions.
