Whether it’s to celebrate a birthday, check eligibility for a job, or figure out how much time has passed since an important event, knowing your age is a key piece of information. One of the easiest ways to find out your age is by using an Age Calculator by Date of Birth. This tool helps you figure out your exact age, down to the day, month, and year, based on when you were born.

In this article, we will explain everything about Age Calculators by Date of Birth. We’ll talk about how they work, why they are useful, and how you can use them to calculate your age. So, let’s get started!

What Is an Age Calculator By Date of Birth?

An Age Calculator by Date of Birth is a tool that helps you calculate your exact age based on the date you were born. This calculator uses your day, month, and year of birth to find out how old you are at any given moment.

For example, if your date of birth is January 1, 2000, and today is April 21, 2025, the Age Calculator will tell you that you are 25 years, 3 months, and 20 days old.

These calculators are simple, fast, and can be used by anyone with a date of birth. You can use them online, on apps, or even in some software tools.

How Does an Age Calculator By Date of Birth Work?

The main function of an Age Calculator is to take your date of birth and calculate the difference between that date and the current date. The difference is your age.

The calculator works in the following steps:

Enter the Date of Birth: You first provide your date of birth. This includes the day, month, and year you were born.
Current Date: The calculator will use the current date (today’s date) to calculate the difference.
Calculate: The tool will subtract your birth date from the current date. It will then give you:
- Your age in years
- Your age in months
- Your age in days

For example:

Date of Birth: January 1, 2000
Current Date: April 21, 2025

The calculator will subtract January 1, 2000 from April 21, 2025 to find:

Age in years: 25 years
Age in months: 3 months
Age in days: 20 days

This is how an Age Calculator works!
