Is Chronological Age Same With Biological Age?

Oftentimes, people tend to mistake chronological age with biological age. They both have different meanings. Your chronological age is simply defined as the amount of time that has passed from your birth to the given date. It is the primary way through which someone defines their age.

While your Biological age is how old your body seems, and it’s based on a number of factors such as how your chromosomes have changed over the years.

What Is An Age Difference Calculator Used For?

Just like an age calculator or date of birth calculator is used to calculate age from date of birth, an age difference calculator is used to calculate the age difference between two people.

For instance, if we are trying to find the age difference between  two people who were born on the 12th January 2000 and 21st March 2015 respectively with an age difference calculator, then the output will be;



The year date was 12.01.2015

No of years are 2015-2000=15 years

No of months are Feb, Mar= 2 months

No. of days remaining 9 days in March= 9 days

So from the calculation given to us by the age difference calculator, the difference between the age of both persons is 15 years 2 months 9 days
