Hidden stems and their Ten Gods

A branch is more than its surface element. Chen 辰 hides Wu 戊, Yi 乙, Gui 癸; read against the Day Master Wu 戊 they give the Ten God relations below. Hidden stems are what element strength is actually judged on — counting only the four visible stems badly understates what the branches carry.

Next Wu Chen 戊辰 days

Day pillars run on a fixed 60-day cycle independent of month and year. The dates below are derived straight from the day count, so no calendar reform affects them.

Where Wu Chen 戊辰 sits in a chart

The day pillar is the only one read from itself — every Ten God in the year, month and hour pillars is defined relative to the Day Master Wu 戊. Two people born in the same year and month with different day stems therefore have completely different charts. In Wu Chen 戊辰 the Day Master Wu 戊 is yang Earth and sits on Chen 辰, which is Earth; the relation between them is the same element. This seat is classically read as the Day Master's immediate environment.
