Day pillar 50 of 60

癸丑 gui chou

Water stem over Earth branch. The yin water day master, sitting on the Ox (丑).

Every structural fact about 癸丑 below can be checked against an almanac; only the passage marked conventionally read as is interpretation.

癸 above, 丑 below

癸 Heavenly stem Water 水 · yin
丑 Earthly branch Earth 土 · Ox

The branch controls the stem: Earth restrains Water. The stem is working against its own footing, which shows up as effort that costs more than it should.

Where 癸丑 sits in the five elements

Wood and Fire do not appear anywhere in this pillar.

Water48.1%
Earth40.7%

Water leads at 48.1%, then earth at 40.7%.

What is buried inside 丑

己Earthprimary
癸Watermiddle
辛Metalresidual

丑 hides 3 stems. The primary is 己 (Earth), what restrains the stem; behind it sit 癸 (Water, the same element as the stem) and 辛 (Metal, what produces the stem).

癸 meeting 丑: the 冠帶 stage

The twelve stages (十二長生): yang stems run forward, yin stems backward.

冠帶
cap and girdle coming of age — capability recognised, standing not yet granted

癸 meets 丑 at the 冠帶 stage — cap and girdle.

丑 against 未, with 子

Opposite across the cycle (六沖), and paired with (六合):

Clashes with
未 (Goat) — 辛未
Combines with
子 (Rat) — 甲子

Nayin: 桑柘木

Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 壬子: 桑柘木, “wood of the mulberry.”

How 癸丑 is conventionally read

癸 is water that arrives quietly: rain, mist, groundwater. 丑 is the last stretch of winter, storing what is not yet ready.

A water-element day master on a earth footing — one of eight characters, which colours a chart and does not fix the person.

When the next 癸丑 days fall

The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 5 December 2026 (Saturday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 癸丑 day, because the day rolls at 23:00 true solar time.

癸 on six different footings

Six pillars carry this stem. It is the same day master every time, so everything that differs below is caused by the branch underneath it:

PillarBranchFootingStage
癸酉酉 · RoosterWater on Metalillness
癸未未 · GoatWater on Earthtomb
癸巳巳 · SnakeWater on Fireconception
癸卯卯 · RabbitWater on Woodbirth
癸丑 ←丑 · OxWater on Earthcap and girdle
癸亥亥 · PigWater on Waterpeak

Here the footing is Earth — what restrains the stem. The other five branches this stem sits on are 酉 (Metal), 未 (Earth), 巳 (Fire), 卯 (Wood), 亥 (Water).
