How to calculate the age of fortune telling _ How to calculate the age of fortune telling, why is it three years old?

Know how to calculate the age of others, and know how to calculate the age of the zodiac.

According to the algorithm of the lunar calendar, the period of each zodiac is 12 years, and beginning of spring is the dividing point, that is, around the Spring Festival every year. The following is the calculation method of age: 1. If you know someone else's birth year, you can subtract the birth year from the current year and add 1 to the corresponding age. For example, if someone was born in 1985 and is now 202 1, then his age is: 2021-1985+1= 37 years old. 2. If you only know the zodiac of other people's birth year, you can calculate the corresponding age by comparing the zodiac of that year with the zodiac of the birth year. For example, if someone else's birth year is "rat" and now it's "cow", then the calculated age is the number of years from the current "rat" year to the birth year before the Spring Festival. Specifically, according to the 24 solar terms algorithm, from beginning of spring in the Year of the Ox to beginning of spring in the Year of the Rat, it takes the Lunar New Year and all other zodiac years in between, that is, 202 1- 1984=37 years, so the corresponding age is 37 years old. It should be noted that the above method is calculated according to the age of the lunar calendar, which may be different from the age of the solar calendar.
