Although Pinnacle Cycles and Period Cycles are both derived from your date of birth, they differ in the way you experience them. Period Cycles, described above, reflect internal stages of growth. Pinnacle Cycles represent the external influences you encounter in life.

Pinnacles reveal general conditions and events you experience during each period, such as your environment, social conditions, relationships, and changing circumstances. Pinnacles reveal how you might respond to these influences and how they will affect your ever-evolving personality.

The transition from one Pinnacle to the next is usually strongly felt. You begin to feel the transition from one Pinnacle to the next approximately two years in advance. The latter part of that two-year period can be particularly strong. You will likely make life-altering decisions, such as marriage, a job or career change, or major changes in your personal makeup.

Knowing and understanding your approaching Pinnacle number prepares you for the changes ahead. Perhaps the most strongly felt change is the transition from First to Second Pinnacle, which usually takes place in your late 20's or early 30's (the exact date depends on your Life Path number). This is usually a difficult transition but once crossed, provides a clear sense of direction and a firmer sense of identity.
