How Count Age With Birthday year

Count Age

Calculating age based on a person’s birthday year involves a straightforward process. Here’s a simple explanation:

  1. Determine the Current Year: First, identify the current year. This is the year in which you are calculating the person’s age.
  2. Identify the Birth Year: Next, find out the year in which the person was born. This is their birth year.
  3. Subtract Birth Year from Current Year: Subtract the person’s birth year from the current year. For example, if the current year is 2024 and the person was born in 1990, you would subtract 1990 from 2024.
  4. Account for Birthdate: If the person hasn’t had their birthday yet in the current year, subtract 1 from the result obtained in step 3. This adjustment ensures that the calculation accurately reflects the person’s age before their birthday occurs in the current year.

Here’s the formula in a more concise form:

Age=Current Year−Birth Year−1

Let’s illustrate this with an example:

If the current year is 2024 and the person was born in 1990: Age=2024−1990−1=34

So, the person would be 34 years old in 2024 before their birthday occurs.
