## How Age Calculator Works?

The Oxford dictionary defines “Age” as the length of time that a person has lived or a thing has existed. The method of calculating age involves the comparison of a person's date of birth with the date on which the age needs to be calculated. The date of birth is subtracted from the given date, which gives the age of the person. Age = Given date - Date of birth. The steps to calculate a person's age from his date of birth to a given date are listed below.

- The first step is to take the difference between the years ( specified year - birth year). Note that a fully completed year is considered.
- Next, we make a note of the number of remaining months. As we only calculate a fully completed year, certain months will be left out that need to be documented.
- Finally, we take the remaining days left. This gives us the final age of a person. It is expressed in years, months and days.

## Solved Examples on Age

**Example 1:** The date of birth of Ron is July 25, 1985 (25/07/1985). Find his age on January 28, 2021, and verify it using the age calculator.

**Solution:**

Using the formula to calculate Ron's age:

Age of a Person = Given date - Date of birth.

Ron's Date of Birth = July 25, 1985.

Given date = January 28, 2021.

Years' Difference = 2020 - 1985 = 35 years.

Number of remaining months from 25 July 2020 to 25 January 2021 = 6 months.

Number of remaining days from 25 January 2021 to 28 January 2021 = 3 days.

Therefore, Ron's age is 35 years, 6 months, 3 days.

**Example 2:** Harry's date of birth is July 13, 1992. Find his age on April 21, 2016, and verify it using the age calculator.

**Solution:**

Using the formula to calculate Harry's age:

Age of a Person = Present date - Date of birth.

Harry's Date of Birth = July 13, 1992.

Years' Difference = 2015 - 1992 = 23 years. (This has been calculated from June 1992 to June 2015.

Number of remaining months from 13 June 2015 to 13 April 2016 = 10 months.

Number of remaining days from 13 April 2016 to 21 April 2016 = 8 days.

Thus, Harry's age will be 23 years, 10 months, and 8 days.
