Working principle

This age calculator basically works by measuring the difference between two points in time. For example, your date of birth is 15-08-1993 and today’s date is – 07-05-2022.

The online age calculator tool assumes these times as point A and point B then it measures the difference between the two in terms of the duration of the time.

Understanding age difference

Age difference refers to the distinction between the ages of two people which can be measured by differentiating between the two dissimilar points of time i.e days, months, and years as time variables.

For example – Neha was born on February 15th, 2001 and Riya was born on September 20th, 2020 then the difference in age between the two will be 19 years, 1 month 5 days.

Another example – A veteran Actor, Heath Ledger who played the role of Joker in The Dark Knight movie died on January 22, 2008. His actual date of birth was April 4, 1979. Using the above Age Calculator Date of birth we can find the total span of life he lived.

In this case, the DOB calculator will pick his date of birth as point 1 and the date of death as point 2. By differentiating them the calculator will show you the result – 28 years 9 months 18 days which means Heath Ledger lived his life only 28 years.

Please note, that similar dates indicate no differences and in the case of 0 difference, the calculator will not show you the result or it may show you 0 outputs.
