Zodiac Sign Calculator

Find your Western sun sign from your birth month and day, with its symbol, element, ruling planet, dates and a short trait profile.

Looking up what a birth date or a name is said to mean: a sun sign, the rest of a birth chart, a life-path number, or the same for someone else before a conversation about it.

Taking a sun sign as the whole chart. Someone born a day either side of a cusp changes sign depending on the year and the time of day, and the moon and rising signs move much faster than the sun does — a birth time is what separates a chart from a guess.

They sit next to each other but answer different questions: Birthstone & Zodiac Flower Finder is the one to open when you need it to look up the modern birthstone and birth flower for any month, with the meaning and symbolism traditionally linked to them. Pick whichever matches what you're starting from — both are free.

Celtic Tree Zodiac Calculator is the closest one after this: Map your birth date to your Celtic tree sign in the 13-tree Ogham calendar, with its Ogham letter, dates and a short trait profile.

Chinese Zodiac Calculator and Mars Sign Calculator — they come up in the same task often enough to be worth a second tab.

The positions are computed from real ephemeris arithmetic, not from a fixed table of dates, so a cusp birthday lands on the right side of the boundary for its own year. What those positions are taken to mean is tradition, not measurement, and the tools present it as such.
