PLUTO & GENERATIONS
What defines a generation? There is no single way to define when a generation begins and ends.
In Western Astrology, a generation is defined by Pluto which stays in a sign for 13-21 years. For example, those born in 1995 to 2008 when Pluto was in Sagittarius are Millennials.
The overlaps you see mark periods when Pluto turned retrograde, and took a step back to the previous sign. . . .
