Maya Tzolk'in Calculator
Enter any Gregorian date to discover its corresponding Tzolk'in day, including tone, day sign, and kin number.
What is the Tzolk'in calendar?
The Tzolk'in is the sacred 260-day cycle used by the Maya. Instead of months, it combines two repeating sequences: 13 tones and 20 day signs. Every day has a unique combination, and after 260 days the cycle restarts.
If you have ever searched for a Mayan birthday calculator, Mayan day sign finder, or kin number tool, this is the system you are looking for.
The 260-day structure
- 13 Galactic Tones: numerical energies from 1 to 13.
- 20 Day Signs: symbolic archetypes such as Imix, Ik', and Ajaw.
- 260 total combinations: 13 × 20 = 260 unique days (also called kins).
How this maya tzolkin calculator works
This tool converts your date into a Julian day count, then maps it into the 260-day Tzolk'in cycle. The output includes:
- Kin Number (1–260)
- Tone (1–13)
- Day Sign (one of 20)
- Signature Format (for example, 4 Ajaw)
The calculator uses the GMT correlation constant, the most common reference for modern academic and practical use.

This is a useful starting point if you are exploring the Long Count, Haab', Calendar Round, or broader Maya astronomy and cosmology.
Frequently asked questions
Is this the same as astrology?
Not exactly. The Tzolk'in is a sacred cyclical calendar system, not a modern horoscope framework, though people may use it in spiritually similar ways.
Why might different calculators show a different result?
Different tools sometimes use different correlation constants or naming conventions. This page uses the widely accepted GMT correlation for consistency.
Can I use this for birth dates before 1900?
Yes. The algorithm works for any valid date supported by your browser's date input, including historical dates.
Final thought
The Tzolk'in invites you to see time as quality, not just quantity. Try your birthday, today's date, and a few meaningful milestones to explore how the 260-day rhythm appears across your life.
