Water in the Zodiac
The Pig and the Rat carry Water. That is the fixed element of the branch — 亥 for the Pig, 子 for the Rat — and 子 is the purest Water in the cycle, which is why a Rat year reads colder than a Pig year.

At a glance
The Pig and the Rat carry Water — and 子 is the purest Water in the cycle.
In the classical correspondence tables Water governs winter and the north, the kidney and bladder, the ears, and the salty taste.
The animals that carry Water
The stem layer supplies the second dimension. 2019 was 己亥, yin Earth on the Pig — Earth damming Water, a year read as constraint on movement. 2020 was 庚子, yang Metal on the Rat — Metal generating Water, the opposite relationship, and the start of the cycle this calendar is currently counting from.
This is the layer that makes the animal useful. A Rat year is always Water, but a 庚子 year and a 甲子 year are different years: one is Metal feeding Water, the other is Wood drawing on it. The sixty-year cycle exists because the two layers move at different speeds.
The practical consequence is the one that applies across this library: the year animal is the shallowest layer available and the one most people arrive through. It is a coarse filter — twelve categories for the whole population — and it is an entry point to the element layer rather than a conclusion.
Years, and the two-layer element
Years
Pig: 2019, 2007, 1995, 1983, 1971, 1959. Rat: 2020, 2008, 1996, 1984, 1972, 1960. The animal cycle is twelve years; the full stem and branch cycle is sixty.
The two-layer element
亥 and 子 are both Water branches. The year's stem adds a second element — 己亥 is Earth on Water, 庚子 is Metal on Water — and the two years read very differently.

How much weight this carries
The zodiac year is the shallowest layer of the system, and it is the one most people arrive through. Twelve animals is a coarse filter: it groups roughly eight percent of the population together and then asks you to believe they share a temperament. The element layer underneath is what makes it specific.

Common questions
Is the Rat a Water sign?
Yes — 子 is a Water branch and the purest Water in the cycle. The year's stem still modifies the reading.
Why is the Pig considered lucky?
Culturally for reasons outside this system. Astrologically 亥 is a Water branch that stores Wood, which the tradition reads as a phase that can generate rather than only store.
Are Pig and Rat compatible?
Both are Water, so the tradition reads them as similar rather than complementary. See the pair pages for what similarity costs.
