We use the names of the constellations but they are in a different position in the sky to when they were first spotted. This is because the earth wobbles on its axis.

Russell said: “Western astrologers use fixed points to determine a mathematically exact zodiac of 360 degrees.

“The Sun might pass through 13 constellations during the course of a year but not all of these have been assigned an astrological sign, not because astrologers have not recognised their existence but because the mathematics of our astrology do not require a 13th, 14th or 15th zodiac sign.”

There you have it, you can comfortably stick to the sign you have always been.
