How to calculate the age of the twelve Chinese zodiac signs?

First of all, we need to know the numbers corresponding to each of the twelve signs of the Chinese zodiac: Rat 1, Ox 2, Tiger 3, Rabbit 4, Dragon 5, Snake 6, Horse 7, Sheep 8, Monkey 9, Chicken 10, Dog 11, Pig 12.

You can make the assumption that, assuming that this year is the year of the dog, then the age of the youngest dog is 1 year old, the youngest chicken is 2 years old, the youngest Monkey is 3 years old, according to the law of the counting down.

The same dog, a different age, each section increases by 12 years, for example, this year's youngest dog is 1 year old, then a large section is 13 years old, and then a large section is 25 years old, and so on.
