How often do the signs change? “Every 26,000 years it slews slowly round in a circle, much like a spinning top wobbling around on a table. This additional motion is almost imperceptible on everyday timescales but over centuries it adds up.” So the stars don’t move, but they appear to move over the course of centuries.
Why did my Vedic astrology sign change? Because of the Earth’s tilt and wobbly orbit, the stars and constellations do not remain in a fixed position. Each fixed star moves about one zodiacal degree every 72 years.
Do zodiac signs change every 30 years? Nope, more like every 30 years. (So you’ve got some time to process all this, thank G.) “There are 30 degrees in each sign, and the progressed sun only moves less than a degree per year, so this change is really slow-moving,” explains Montúfar.
How often does each planet change signs? These celestial bodies — Jupiter, Saturn, Uranus, Neptune, and Pluto — move much more slowly, changing signs every one to thirty years. The outer planets define larger life themes, as well as experiences shared by generations.
