Mao (卯) Earthly Branch in Bazi

Definition and place in the cycle

Mao is fourth in the cycle, between Yin and Chen at the center of spring.

Mao (卯) is classified as a Yin Wood Earthly Branch. Its animal is a calendrical mnemonic; neither the animal nor the phase alone establishes personality, strength, or outcome.

Season, solar month, and double-hour

Mao (卯) governs the 2nd solar month · begins near awakening of insects and is associated with mid-spring. The listed civil-clock double-hour is 05:00–06:59.

Mao represents the concentrated middle phase of spring Wood rather than the first movement or closing transition of the season. Solar-term boundaries and the time standard used for a chart can shift the practical calendar or hour boundary, so calculate the chart rather than guessing from a date or wall clock alone.

Hidden stems and chart role

Mao (卯) conventionally contains 乙 Wood. Hidden stems describe internal elemental layers and possible roots; this page does not assign fixed weights because schools and calculation methods differ.

Mao conventionally contains Yi Wood alone, but a single hidden stem does not make its chart function simple or automatically favorable.

Branch relations and reliable reading boundary

Mao (卯) forms a Six Harmony pair with Xu (戌), a Six Clash axis with You (酉), and a Wood trine group with Hai (亥) and Wei (未). A listed relation is a structural possibility, not proof of a favorable, harmful, or transformed result.

• Read month command, pillar position, hidden stems, visible stems, support, control, and timing together.
• Do not reduce an Earthly Branch to its zodiac animal or one personality adjective.
• Do not assume that a harmony, clash, or trine automatically activates or decides the whole chart.
