Rat years
- #1 of 12
- Element: water
- midwinter
- 23~01h
The rat opens the cycle of twelve. It holds the deepest hour of midwinter — and that this darkest point is also the starting point is the clue to reading it. The arrangement treats an empty board as the moment to move first.
The rat is usually called clever. In the chart that impression traces to its branch being the purest water position of the twelve. Water takes the shape of whatever holds it, which shows up as speed in reading a situation and adjusting.
Only two stems hide inside this branch, and both are water. Nothing inside redirects it. That is why the rat swings more than most on whichever heavenly stem sits above — the five versions of this sign look quite different from one another.
The five year pillars inside this sign
The branch stays the same; the heavenly stem above it changes every twelve years, and with it the whole reading. Find your birth year below.
Green Rat甲子
1924 · 1984
Water pushing wood upward — quick to absorb, slow to settle into shape.
Red Rat丙子
1936 · 1996
Fire over water keeps a baseline tension, and that tension sharpens the senses.
Yellow Rat戊子
1948 · 2008
Earth holding water — a large capacity to contain, and little of it shows.
White Rat庚子
1960 · 2020
Metal releasing water — thought moves quickly into speech and output.
Black Rat壬子
1972 · 2032
Water above and below — the drive and the excess share one root.
Which signs Rat meets well
Branch relations are fixed by position in the cycle, so they hold for every year of this sign.
Six harmony — the easiest pair
Water and earth lock together and hold each other in place. The ox catches the rat's quick judgment and gives it a form.
Trine — the group that gets things done
Together these three form a water frame. Their strength shows where information and flow are handled.
Clash — meeting head-on
Water and fire face each other across the widest gap in the cycle. The collision is large, and so is how much they move each other.
Hidden grudge — friction without a reason
Nothing big goes wrong, and something keeps catching anyway. Water and dry earth do not absorb into each other; they circle.
Sign-to-sign is the coarse layer — one twelfth of the population shares it. Real compatibility is read from the day pillar, which needs a birth date.
One catch: Ipchun, not January 1
A sign does not change at midnight on January 1. It changes at Ipchun, the solar term falling around February 4. Someone born in January 2020 is not Rat — that birthday still belongs to Pig, the 己亥 year. If you were born in January or the first days of February, the sign most sites hand you may be off by one. ARO reads the solar-term boundary, computed to the minute.
Your sign is one of four characters in your chart. The other three — month, day, and hour — decide how it actually plays out.
