Exact Age Calculator: Years, Months, Days, Hours, Minutes, Seconds

What is an Exact Age Calculator?

An exact age calculator is a precise tool that computes a person's age down to the second, based on their birth date and time, and a specified end date and time (usually the current date and time). It provides a detailed breakdown of age in years, months, days, hours, minutes, and seconds, offering a comprehensive view of the time elapsed since birth.

Formula

The formula for exact age calculation is based on the difference between two dates:

\[ \text{Exact Age} = \text{End DateTime} - \text{Birth DateTime} \]

Where:

• \(\text{Exact Age}\) is the calculated age in years, months, days, hours, minutes, and seconds
• \(\text{End DateTime}\) is the date and time for which the age is being calculated
• \(\text{Birth DateTime}\) is the person's date and time of birth

Calculation Steps

1. Identify the birth date and time: \(B = \text{Birth DateTime}\)
2. Determine the end date and time: \(E = \text{End DateTime}\)
3. Calculate the difference: \(\text{Exact Age} = E - B\)
4. Express the result in years, months, days, hours, minutes, and seconds

Example

Let's calculate the exact age of a person born on March 15, 1990, at 14:30:00, as of June 1, 2023, at 09:45:30:

1. Birth DateTime (B): March 15, 1990, 14:30:00
2. End DateTime (E): June 1, 2023, 09:45:30
3. Exact Age = June 1, 2023, 09:45:30 - March 15, 1990, 14:30:00
4. Result: 33 years, 2 months, 16 days, 19 hours, 15 minutes, 30 seconds
