Age Calculator

This free age calculator computes age in terms of years, months, weeks, days, hours, minutes, and seconds, given a date of birth.

The age of a person can be counted else in different societies. This calculator is grounded on the most common age system. In this system, age grows at the birthday. For illustration, the age of a person that has lived for 3 times and 11 months is 3 and the age will turn to 4 at his/ her coming birthday one month latterly. utmost western countries use this age system. 
 
 In some societies, age is expressed by counting times with or without including the current time. For illustration, one person who's twenty times old is the same as one person who's in the twenty-first time 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 rather of birthday. For illustration, if one baby was born just one day before the Traditional Chinese New Year, 2 days latterly, the baby will be at age 2 indeed though he she is only 2 days old. 


In some situations, the months and days affect of this age calculator may be confusing, especially when the starting date is the end of a month. For illustration, we all countFeb. 20 to March 20 to be one month. still, there are two ways to calculate the age fromFeb. 28, 2015 toMar. 31, 2015. If allowingFeb. 28 toMar. 28 as one month, also the result is one month and 3 days. If allowing bothFeb. 28 andMar. 31 as the end of the month, also the result is one month. Both computation results are reasonable. analogous situations live for dates likeApr. 30 to May 31, May 30 to June 30, etc. The confusion comes from the uneven number of days in different months. In our computation, we used the former system.
