# What Zodiac Sign Am I?

### Get the answer with this Zodiac Calculator

**Are you sure about your Zodiac sign? Here is a calculator to check it. It computes the exact position of the sun at your time of birth (your Sun sign or Zodiac sign), and gives the result instantly!**

## The Zodiac Sign Calculator

Here is the Zodiac sign calculator. Fill in the form with your birth time (year, month, day, and time) and the city where you were born.

If you don’t know the time of day of your birth, make it 12:00 noon, so that it can be no more than 12 hours wrong.

Then press the button *Get Your Zodiac Sign*. The wheel will turn until the arrow is at the right spot. Your Zodiac sign will be reported, also the degree within that sign (between 0° and 30°).

## Tested

The Zodiac sign calculator is based on contemporary astronomical formulas of celestial mechanics. I have compared the results with those given by astronomical sources, such as the ephemeris of , as well as with a few advanced astrological horoscope calculation programs. 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.

In that rounding off, though, there is no change of Zodiac sign allowed. That means 29.99° is not rounded off to 30° (which would be 0° of the following Zodiac sign), but to 29.9°. This is done not to result in the wrong Zodiac sign given in the result. Still, if that’s your Zodiac sign position, your character traits would really be a mix of that sign as well as the next.

Your Zodiac sign is the position of the sun in the Zodiac circle at the time of your birth, as seen from earth. That perspective is called geocentric. But of course, the earth moves around the sun, not the other way around. 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.

The diameter of the sun as seen from earth is half a degree, but its position is given for the center of it.

In astrology, the position of the sun within a Zodiac sign (between 0° and 30°) is of importance in the reading. That is why you should know not only your sign, but the degree within that sign. So, I hope you find this tool useful for your further understanding of astrology and the meaning of your Zodiac sign.

## Many Inaccurate Caculators

One of the main reasons for creating this Zodiac sign calculator is that I’ve found so many inaccurate ones on the Internet. There are countless Zodiac sign calculators on the world wide web, but many of them are not at all trustworthy.

If you have used another calculator to ascertain your Zodiac sign, please consider the following:

- Zodiac sign calculators that give no degree within the sign in the result are insufficient and often based on a simple table of mean Zodiac dates, with no consideration of leap years. That can give you the wrong Zodiac sign if you were born close to a change of Zodiac signs.
- Zodiac sign calculators that don’t ask for the time of day you were born can’t give you the degree of the Zodiac sign with any precision. If you are born near a change of Zodiac signs they can give the wrong one.
- Zodiac sign calculators that ask for neither your birth place nor the time zone of it have the same inaccuracy as those not calculating with the time of day of your birth.
- Even those Zodiac sign calculators that ask for all the necessary information may use simplified computing and therefore sometimes give results that can be a degree or even more off. That even goes for some astrological horoscope calculation programs.
