The individual's age can be calculated differently in different cultures. This calculator is based on the most common age system. In this system, life grows at Christmas. For example, the age of a person who lived for 3 years and 11 months is 3 years and will be 4 years old on his next birthday after one month. Most Western countries use this age system.

In some cultures, age is expressed by calculating the years with or without the current year. For example, one person twenty years old is the same person as one in the twenty-first year of his life. In one of the systems of the traditional Chinese era, people are born at the age of 1 and grow old in traditional Chinese New Year instead of Christmas. For example, if a child is born one day before the traditional Chinese New Year, two days later the child will be two years old even though he is two days old.

In some cases, the months and days of this age calculator may be confusing, especially when the start date is the end of the month. For example, we all calculate the month of January. 20 to 20 October to be one month. However, there are two ways to calculate the age of January. 28, 2019 to November. 31, 2019. If January thinking. 28 to November. 28 months, then the result is one month and 3 days. If you think of January. 28 and November. 31 at the end of the month, then the result is one month. Both calculation results are reasonable. There are similar cases for dates like March. From 30 to 31 September, from 30 May to 30 August, and so on. The confusion comes from an uneven number of days in different months. In our account, we used the previous method.
