Your Mayan sign is your Day Sign, one of the 20 signs in the 260-day Tzolkin calendar. It comes straight from your birth date, and the Maya read it as the core of who you are.
How to find your Mayan sign
Enter your birth date in the Mayan sign calculator. In a second or two you get three things: your Day Sign, your Galactic Tone (a number from 1 to 13 that colors how that sign shows up), and your Trecena, the 13-day wave you were born into. You do not need your birth time or place, and you can look up as many people as you like.
What your sign tells you
Where Western astrology gives everyone born in a month the same sign, the Tzolkin runs on 260 day-energies, so your sign is tied to the exact day you were born. That tends to feel more personal. Your Day Sign points to your strengths, the things you wrestle with, and the kind of life that suits you.
