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 260-day sacred calendar of the Maya, and it never ends. It comes from 20 day signs combined with 13 tones, which makes 260 unique day-energies, and that combination defines your Mayan sign. It has no astronomical basis. The Maya revealed it through shamanic trance rather than by watching the sky, so it tracks spiritual time, not the planets.

What is the Mayan Tree of Life?

Your personal chart, built on the principle as above and so below. Your Day Sign sits at the center, with a day sign in each of the four directions: your past behind, your future ahead, your masculine power on one side and your feminine on the other. That center and four directions make five signs, and the complete Tree of Life opens into nine.

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. Your first three completed date lookups are free. After that, sign up for a free account to keep using the calculator for partners, family, and friends.

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.
