Let's travel back in time 3000 years, to the time of the Babylonians, when the astrological horoscope was first created. Muted yellow clay-brick houses surround the marketplace. Brilliantly colored towers gilded with gold soar in the distance. The lispy rhythm of the Aramaic tongue flow around you. Swarthy merchants call out to you to look at the latest in jewelry fasion, made from the rare and expensive metal iron.
The sun slides out of view, silhouetting the skyline. A cool desert breeze whirls its way through the streets. You look up into the sky, and see the familiar constellations, but you notice that something isn't quite the same...
A half-remembered science lecture flitters into your mind. What did your professor say? Ah yes, something about the gravity of the moon pulling on the earth and changing its tilt. You suppose that would explain why the stars are in different places
You remember asking your professor, "Wouldn't that mean that birth signs would change, as constellations move to different places in the sky?"
"Indeed," he replied. "As a matter of fact, the sun passes through 13 constellations, not just the 12 usually used in astrology."
