Year of the Rat: what it does and doesn't tell you
A Rat year means the year branch is Zi, midwinter water. See what that branch marks in a Four Pillars chart, and what it leaves open.

What the Rat year branch means in the Four Pillars
Rat is the common name for the Earthly Branch Zi (子). A Four Pillars chart has eight characters: a Heavenly Stem and an Earthly Branch for the year, month, day, and hour. In a Year of the Rat label, the animal identifies the year branch.
Zi is water, on the yang side of the twelve-branch cycle. Yang and yin are alternating labels in that cycle, not genders. As a month, Zi falls in midwinter, around the winter solstice. As a year branch, it names the year on the chart that begins at Start of Spring, usually February 3, 4, or 5. A birthday in January or early February can sit on a different year branch from the animal on a Lunar New Year list.
Zi stores a single Heavenly Stem, yin water. A traditional picture is water held through the cold, a reserve under the freeze, rather than a river in motion. The picture describes the branch. Across sixty years, Rat years use five different stems beside that branch, so two Rat years are not the same pair of characters. Zi can also appear in the month, the day, or the hour, with the same Rat correspondence.
Common Western zodiac-style readings and why we don't do that
English pages in a horoscope style often assign the Rat a personality: quick, charming, a little calculating. Many add a grid that pairs one animal with another.
One branch cannot carry a personality. It does not score intelligence or social skill, and a count of water elsewhere on the chart is not a character measure. Traditionally, teachers treat the year pillar as the outer layer: the calendar setting of the birth year, sometimes a hint about early surroundings. That is a way of looking, and it stays at the level of a tendency.
What to look at instead
Find the Day Master, the Heavenly Stem of the day pillar. The date is the place to start. Near midnight, the birth time can decide which day applies, and the time also sets the hour pillar. Two charts with Zi in the year can have different day stems. The month branch shows the season, which this system weighs heavily.
You can observe how Zi's water sits relative to the Day Master: the same element, or on the producing or restraining side of the cycles of the Five Elements. Traditionally, that link is a tendency inside the chart.
Your animal is only the year branch of your chart. Find your Day Master with your birth date and time.
