This page only shows how the animal, the year and the months relate under calendar rules. It is not a prediction of events and not advice on health, money or marriage.
Relation to Thái Tuế (Tai Sui) in 2025 (Ất Tỵ)
The Rat and the year's branch Tỵ are not in a same-sign, clash, harm, six-harmonies or triple-harmony relation: a neutral Earthly Branch relation.
Some books also consider Phá (break) and Hình (punishment) with Thái Tuế, but sources disagree so they are not listed here.
The Rat is not in Tam Tai this year. The Tam Tai years of this group are: Dần, Mão, Thìn.
By specific birth year (ages 20 to 70)
