The Basics of Age Calculation

Calculating age might seem straightforward, but it can get tricky when you start considering different factors.

  1. Starting Year Matters:

Begin with the year when the person was born.

For instance, if you were born in 2000, calculating your age in 2020 is straightforward.

  1. Subtract the Birth Year:

Subtract the birth year from the current year.

Example: 2020 – 2000 = 20.

  1. Consider the Month and Day:

If the birthday hasn’t occurred yet for the current year, subtract one from the result.

Example: Born in June 2000, calculating age in April 2020 would be 19.
