Luck Cycles — the decades of your chart

A BaZi chart is not a snapshot — it is a weather system that moves. Luck cycles (大运) are the ten-year seasons of that system, and knowing your current one explains more about “why this decade feels like this” than anything else in the tradition.

Every chart carries a sequence of ten-year luck cycles, each named by a stem and branch. The first begins in childhood and each lasts exactly ten years, running through the decades of your life. The element of each cycle — its stem and branch — meets your Day Master like a new season: one decade is your spring, another your harvest, another your winter.

Why the decade feels different

People change far less than the weather they live in. A Wood day master moving into a Water decade is being watered — growth years, often busy and fertile. The same person in a Metal decade faces the blade — years that demand cutting, deciding and letting go, whatever they try to keep. Knowing which season you are in turns confusion into strategy: you stop fighting autumn and start harvesting it.
