Calculate the age of a person, place or anything else. This age calculator calculates age for a date of birth on any given date in years, months and days. Calculate age in months and days and, calculate age in days total only.
* The year here is 365 days and the month here is 30 days, that means your birthday may not mean you will be 0 days old.
How Age Calculator Works
The age of a person can be counted differently in different cultures. This calculator is based on the most common age system. In this system, age grows at the birthday. For example, the age of a person that has lived for 3 years and 11 months is 3 and the age will turn to 4 at his/her next birthday one month later. Most western countries use this age system.
In some cultures, age is expressed by counting years with or without including the current year. For example, one person is twenty years old is the same as one person is in the twenty-first year of his/her life. In one of the traditional Chinese age systems, people are born at age 1 and the age grows up at the Traditional Chinese New Year instead of birthday. For example, if one baby was born just one day before the Traditional Chinese New Year, 2 days later the baby will be at age 2 even though he/she is only 2 days old.
In some situations, the months and days result of this age calculator may be confusing, especially when the starting date is the end of a month. For example, we all count Feb. 20 to March 20 to be one month. However, there are two ways to calculate the age from Feb. 28, 2015 to Mar. 31, 2015. If thinking Feb. 28 to Mar. 28 as one month, then the result is one month and 3 days. If thinking both Feb. 28 and Mar. 31 as the end of the month, then the result is one month. Both calculation results are reasonable. Similar situations exist for dates like Apr. 30 to May 31, May 30 to June 30, etc. The confusion comes from the uneven number of days in different months. In our calculation, we used the former method.
How To know Your Exact Age With Your Birth Date
You should know that most of calculator and systems don’t follow the above rules and in some cases they counted all the months by 30 days only. So sometimes you mightn’t get accurate result from them and age result can be different 1-4 days if you compare the result among us and other ordinary calculator or systems.
Be sure the above result is the difference between birth date and target date. And the day of birth is not included to the result.
Let's, A child boarn in first day in a month, how old will he on the date 9th in the same month?
Equation: Displayed Age = target date – birthdate
Example: Age = 9 - 1 = 8 days old. (actually it is not right)
Your accurate age should be = target date – birthdate + birth day (+1).
Actual age = 9 - 1 +1 = 9 days old.
So you must add a day (+1) to calculated result if you want to use your age in any document.
If you see the result of days are displayed 29 or 30 you should consider the number of days of relevant months when you will add +1 days.
You should know January is counted by 31days, February 28 & 29days, March 31days, April 30days, May 31days, June 30days, July 31days, August 30days, September 31days, October 31days, November 30days and December 31 days.
See, how to add +1 with the calculated age:

Let’s, your age is 19 years 8 months 30 days (figure 2).
Be sure if the month of above age is 8 and it must be August. And the days 30 must be for the next month September which is running month and uncompleted.
How to understand that the calculated age is right or wrong?
You can justify your age with the following equation:
(Your age (excluding +1) + Date of birth = Target date)
Sum of your age and date of birth must be same to target date. If not your calculated age is wrong.
