What is an Age Calculator?

An age calculator is a tool that computes a person's age based on their birth date and a specified date (usually the current date). It provides the age in years, and sometimes in months and days for more precise results.

Formula

The general formula for age calculation is:

\[ \text{Age} = \text{End Date} - \text{Birth Date} \]

Where:

  • \(\text{Age}\) is the calculated age
  • \(\text{End Date}\) is the date for which the age is being calculated (usually the current date)
  • \(\text{Birth Date}\) is the person's date of birth

Calculation Steps

  1. Identify the birth date: \(B = \text{Birth Date}\)
  2. Determine the end date: \(E = \text{End Date}\)
  3. Calculate the difference: \(\text{Age} = E - B\)
  4. Express the result in years, and if needed, in months and days

Example

Let's calculate the age of a person born on March 15, 1990, as of June 1, 2023:

  1. Birth Date (B): March 15, 1990
  2. End Date (E): June 1, 2023
  3. Age = June 1, 2023 - March 15, 1990 = 33 years, 2 months, and 17 days
