How to calculate the age of one full year?

One full year of life is one year old, calculated according to the Gregorian calendar, starting from the second day of one-year-old birthday. For example, a person who was born on June 65438+1 October1in 2000 has been born on August 3 1 in 20 15. Fifteen years and nine months have passed since his birth, and his complete age is fifteen years and nine months.

Nominal age

This is a traditional method of calculating age in China, and it is also popular in other countries in East Asia. It is used to calculate the sequence (ordinal number) of the years that a person is experiencing after birth, which is based on the year when he was born, because this is the first year after birth and has nothing to do with the pregnancy he has experienced in the past year. It is different from the current international age calculation method, which calculates the elapsed time after birth (as a base, it can also calculate the mantissa, such as three years and two months, seven and a half years, etc. ).

a whole year

This is an internationally accepted age calculation method. It calculates the length of time that has passed since birth (as a cardinal number, it can also calculate the mantissa, such as three years and two months, seven and a half years old, etc. ). In China, in order to compare with the traditional way of calculating age, that is, to calculate the order (ordinal number) of years after birth, there are two names: one year old and nominal age.

Note: Gregorian calendar increases by one year every birthday. This way of calculating age is a recognized tradition and does not require legal provisions. In our country, in order to reduce disputes, the relevant laws delay the calculation of the day of the week for minors who commit crimes by one day, which is only a special case.
