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.
