How old are you now in 2020?

Are you asking how old you have been since 2002? 20 years old.

The calculation method is to subtract 2002 from 2022, that is, subtract the year of birth from the current year, and the number obtained is the actual age. However, in 2002, the horse still has a nominal age, because according to the traditional age calculation method in China, once a person is pregnant in his mother's body, he has already started to calculate his age, so even if he is one year old at birth, the nominal age of the horse in 2002 will be 2 1 year in 2022.
