How Age is Calculated

Calculation of Age is very easy. Let me explain it to you with this simple example.

Let's say I was born on November 21, 1988 (21/11/1988 in DD/MM/YYYY format).
Today is 5/01/2023. So, my most recent birthday was on 21/11/2022.
Therefore, 21/11/2022 - 21/11/1988 = 0/0/34.
So, I am more than 34 years old now.
Currently, the date is January 5, 2023.
No of months and days between November  21, 2022 and January 5, 2023 is 1 month and 14 days.
So, my age is now 34 year. 1 month and 14 days.

This is how age is calculated. The calculations are not affected by the time zone of a person since the tool just tells you the difference in time. The age calculator by date is based on the common age system, therefore it can be used by everyone everywhere.
