You (酉) Earthly Branch in Bazi

Definition and place in the cycle

You is tenth in the cycle, between Shen and Xu at the center of autumn.

You (酉) is classified as a Yin Metal 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

You (酉) governs the 8th solar month · begins near white dew and is associated with mid-autumn. The listed civil-clock double-hour is 17:00–18:59.

You represents the concentrated middle phase of autumn Metal, distinct from Shen’s opening and Xu’s closing transition. 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

You (酉) conventionally contains 辛 Metal. Hidden stems describe internal elemental layers and possible roots; this page does not assign fixed weights because schools and calculation methods differ.

You conventionally contains Xin Metal alone, but strength and usefulness still depend on month command, support, control, and chart role.

Branch relations and reliable reading boundary

You (酉) forms a Six Harmony pair with Chen (辰), a Six Clash axis with Mao (卯), and a Metal trine group with Si (巳) and Chou (丑). 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.
