Understanding the Basics of Age Calculation

Age calculation might seem simple, but it involves more than just subtracting years. Understanding the basics helps in accurate calculations.

The Simple Subtraction Method

The most straightforward way to calculate age is by subtracting the birth year from the current year. For instance, if it’s currently 2023 and someone was born in 2002, their age would be:

However, this method doesn’t account for the exact date of birth and date of calculation.
