Generally speaking, when you know the date of birth, you know your age. However, in our real life, there is a saying that you have a nominal age and one year old, but many people don't know how to calculate them. So what is the age formula for calculating the date of birth of a nominal age and one year old? Let's come together and analyze it!

First, the nominal age calculation

There is no fixed algorithm for the nominal age. The nominal age is a commonly used age calculation method in China. It is calculated according to the calendar year after birth, that is, it is 1 year after birth, and it will increase 1 year after every New Year. Simply speaking, the nominal age is related to the Chinese New Year. For example, a baby born at the end of February is counted as 1 year after birth, and it is counted as 1 year after the Gregorian calendar 1 month/day or the local Chinese New Year. In this way, the baby has been born for only a few days, and it is already 2 years old. The age formula for calculating the date of birth in nominal age is nominal age = this year-year of birth+1.

Second, the calculation of one-year-old age

One-year-old age is related to birthdays. One-year-old age, also known as full-time age, refers to the number of anniversaries or birthdays experienced by * * * from birth to the time of calculation. The formula for calculating the age of one-year-old birth date is: one year old = this year-the year of birth (the birthday has passed) (even if the birthday has not passed-1). One-year-old age is often1~ 2 years younger than nominal age, which is a commonly used age calculation method in population statistics. One-year-old-0 years old at birth, and every calendar birthday is 1 year old. For example, a baby born on the 5th day of 20 18/February 1 9 this year is 2 years old in nominal years, but it has just been more than 6 months and has not had a birthday, so it should be less than1one year old in one year, that is, 0 year old.

Summary: Through the above, you have some understanding of the age formula for calculating the date of birth. The algorithmic formulas of nominal age and full age are different. If you want to calculate your age, you must distinguish between nominal age and full age, and then you can do it according to each formula.
