Born on September 27.  That's me.  That makes me a Libra, right?

Nope.

You see, the astrological signs were developed by ancient astrologers, based on scientific observations of the locations of the sun within constellations.  For example, the sun was "in" the constellation of Aries between March 21 and April 19, so people born between those dates had the zodiac sign of Aries. 

That's all well and good, but those ancient scientists hadn't factored in something.

Here's the technical explanation:

Unbeknownst to the ancient astrologers, the Earth continually wobbles around its axis in a 25,800-year cycle. This wobble – called precession – is caused by the gravitational attraction of the Moon on Earth's equatorial bulge.

Over the past two-and-a-half millennia, this wobble has caused the intersection point between the celestial equator and the ecliptic to move west along the ecliptic by 36 degrees, or almost exactly one-tenth of the way around. This means that the signs have slipped one-tenth-or almost one whole month-of the way around the sky to the west, relative to the stars beyond.

What does this mean?  Well, if you were born between March 21 and April 19, your astrological sign is said to be Aries. But this was only true for a while, back when the system was set up in 600 BC. Today, the Sun is no longer within the constellation of Aries during much of that period. From March 11 to April 18, the Sun is actually in the constellation of Pisces!

So, assuming you were born in the last 80 years or so, this is the actual zodiac sign that you were born under:
