The 60 Jiazi Cycle Explained
The 60 Jiazi cycle pairs the 10 Heavenly Stems with the 12 Earthly Branches to form 60 unique combinations. Used for centuries to track time, it’s the core foundation of BaZi astrology.
Core Concepts
The 10 Heavenly Stems
Representing celestial energy, these stems split into yin and yang and map directly to the Five Elements.
The 12 Earthly Branches
Representing earthly energy, these branches correspond to the 12 Chinese zodiac animals and are used to map out the hours.
How Stems and Branches Pair
Pairing the Heavenly Stems with the Earthly Branches creates exactly 60 unique combinations.

Cycle Patterns
Heavenly Stem Cycle (10-day rotation)
The Heavenly Stems cycle in order, repeating every 10 days. Across the 60 Jiazi cycle, each stem appears exactly 6 times. This core rule dictates the stem's position in every combination.
Earthly Branch Cycle (12-year rotation)
The 12 Earthly Branches cycle through Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai, repeating every 12 years. Each branch shows up exactly five times in the 60 Jiazi cycle. They align one-to-one with the Chinese zodiac and are a cornerstone of traditional Chinese timekeeping.
The Least Common Multiple Principle
The least common multiple of 10 and 12 is 60, so the Heavenly Stems and Earthly Branches pair up every 60 years to form the 60 Jiazi cycle. This pattern has been used for centuries to track years, months, days, and hours. The 60 Jiazi cycle isn’t just a timekeeping tool—it captures the ancient understanding of cosmic rhythms.
60 Jiazi Nayin Chart
Nayin (elemental sound) is a core concept in traditional BaZi. Every pair of consecutive Jiazi shares the same Nayin element, resulting in 30 unique types.
What Is Kongwang?
Kongwang is a key concept in the 60 Jiazi cycle. It refers to the two Earthly Branches that fall outside each 10-year cycle. It plays a major role in BaZi analysis.
How Kongwang Forms
Each 10-year cycle pairs with 10 Jiazi combinations, but there are 12 Earthly Branches. The two that don’t get paired are called Kongwang. This is a natural result of the mismatch between the 10 Heavenly Stems and 12 Earthly Branches. In a BaZi chart, these branches carry weaker energy, but they can also unlock unique opportunities and unexpected shifts.
How Kongwang Affects Your Chart
Weakened Energy
Branches in Kongwang carry weaker energy, which affects their corresponding Five Elements. If a Ten God falls into Kongwang in your BaZi chart, its influence drops significantly. You’ll need to read it alongside other chart elements for a full picture.
Higher Volatility
Kongwang signals instability, meaning things in this area tend to fluctuate. Expect shifts and stay adaptable so you can pivot when opportunities arise.
Hidden Opportunities
Kongwang can also hide unexpected opportunities. Depending on your chart, it might actually neutralize negative influences and open doors you didn’t see coming.
How the 60 Jiazi Cycle Is Used in BaZi
The 60 Jiazi cycle is the foundation of BaZi. Your birth year, month, day, and hour each map to a specific Jiazi pair, combining to form your unique four-pillar chart.

Day Master Analysis
The Heavenly Stem of your Day Pillar represents you and sits at the center of your BaZi chart. Its Five Elements attribute reveals your core personality and life structure. Whether it’s strong or weak—and which elements it favors or avoids—directly shapes your life path.
Ten Gods Relationships
By mapping how your Day Master interacts with other stems and branches, we calculate the Ten Gods. These ten archetypes directly reflect the opportunities and challenges you’ll face across every area of life.
Major & Annual Luck Cycles
Every ten years brings a new Major Luck Cycle, and each year shifts your Annual Luck—both following the 60 Jiazi cycle. By analyzing how they interact with your natal chart, we can forecast upcoming trends. These shifting cycles directly shape the highs and lows of your journey.
Chart Pattern Assessment
By analyzing how the 60 Jiazi combinations align across your four pillars, we assess your chart’s overall structure. Patterns like Jia-Zi or Yi-Chou (Nayin Metal) often point to prosperity. The Nayin elemental sounds are a key reference for evaluating your life’s potential.
