Free Tzolkin birth-date calculator
How the Mayan Sign Calculator Works
Enter a birth date to find its Day Sign, Galactic Tone, and Trecena in the 260-day Tzolkin calendar. The 20 Day Signs describe different forms of life energy. The 13 Galactic Tones describe how strongly and in what manner that energy moves.
Your central Day Sign is the starting point of a Mayan astrology reading. A complete nine-position Tree of Life connects your central sign with supporting Youth and Mature positions, and with masculine and feminine aspects.
Your free Mayan birth chart: three starting points
- Day Sign: one of the 20 signs associated with your birth date.
- Galactic Tone: a number from 1 to 13 paired with your Day Sign.
- Trecena: the 13-day cycle that contains your birth date.
Which Mayan calendar does the calculator use?
The calculator follows the continuous Tzolkin count. Its 20 signs and 13 numbers repeat every 260 days. Other websites may use the modern Dreamspell system, so a similar-looking calculator can give a different result. Read our guide to Mayan astrology dates and the Tzolkin for the background.
Your birth date is enough: no birth time, location, payment or sign-up is needed for the free calculation. Use the date controls above to look up yourself or another person. The interpretations are a starting point for reflection, rather than a fixed prediction.

Mayan Sign Calculator Questions
What is a Mayan zodiac sign?
A Mayan zodiac sign, or Day Sign, is the primary energy present on the day you were born. The Maya call these signs Nawales, and there are twenty of them in the sacred Tzolkin calendar. It is the resonance you came in with, so it points to your character and life purpose.
How is a Mayan sign calculated from a birth date?
It is worked out from your birth date and the 260-day Tzolkin calendar, which gives you your Day Sign, Galactic Tone, and Trecena in seconds.
What is the Tzolkin calendar?
The Tzolkin is the Maya sacred calendar of 260 days. It combines 20 Day Signs with 13 Galactic Tones, producing 260 sign-and-number combinations before the cycle repeats. A birth date has its own place in that continuous count.
What is the Mayan Tree of Life?
Your Mayan Tree of Life is a personal chart with nine positions. Your central Day Sign connects with Youth and Mature positions, and with masculine and feminine aspects. The free calculator introduces your central sign; the Detailed Report explains the complete nine-sign pattern.
How accurate is the calculator?
It uses the traditional Tzolkin math that Maya day keepers follow, so the Day Sign and Tone are correct. The readings are an interpretation, meant for reflection rather than fortune telling.
Do I need my birth time?
No. Your Day Sign comes from the date alone, so month, day, and year are all you need.
Can I look up other people?
Yes. The calculator is free and unlimited. You can look up partners, family, friends, historical dates, or future dates without creating an account.
What is a Galactic Tone?
A number from 1 to 13 that pairs with your Day Sign. The Maya saw these like musical tones and held 13 as the sacred number of the divine plan. A higher tone means a stronger charge, so 13 Jaguar is the most powerful Jaguar.
