There are countless Zodiac sign calculators on the world wide web, but many of them are not at all trustworthy.

One of the main reasons for creating this Zodiac sign calculator is that I’ve found so many inaccurate ones on the Internet. So, I hope you find this tool useful for your further understanding of astrology and the meaning of your Zodiac sign.

That is why you should know not only your sign, but the degree within that sign. In astrology, the position of the sun within a Zodiac sign (between 0° and 30°) is of importance in the reading. The diameter of the sun as seen from earth is half a degree, but its position is given for the center of it. So, what’s calculated is the earth position in the Zodiac as seen from the sun (heliocentric) – and the exact opposite of that value, 180°, is the sun sign position. But of course, the earth moves around the sun, not the other way around. Your Zodiac sign is the position of the sun in the Zodiac circle at the time of your birth, as seen from earth. Still, if that’s your Zodiac sign position, your character traits would really be a mix of that sign as well as the next. This is done not to result in the wrong Zodiac sign given in the result. That means 29.99° is not rounded off to 30° (which would be 0° of the following Zodiac sign), but to 29.9°. In that rounding off, though, there is no change of Zodiac sign allowed. The test runs showed that this Zodiac sign calculator is quite accurate to the hundredth of a degree, which is why the result is rounded off to the decimal. I have compared the results with those given by astronomical sources, such as the ephemeris of The Astronomical Almanac, as well as with a few advanced astrological horoscope calculation programs. The Zodiac sign calculator is based on contemporary astronomical formulas of celestial mechanics.
