Age Calculator
Age Calculator – A Complete Guide
An Age Calculator is a digital tool designed to determine a person’s exact age from their date of birth. It provides results in terms of years, months, and days. This tool is commonly used in schools, workplaces, hospitals, and various government services where age verification is required.
What is an Age Calculator?
An age calculator takes a date of birth as input and calculates the current age by comparing it with today’s date. It can also be customized to calculate age from a birth date to any specific date, not just the current day.
For example, if someone was born on January 1, 1990, and today is July 26, 2025, the calculator will show the exact age as 35 years, 6 months, and 25 days.
How Does an Age Calculator Work?
The tool uses date and time functions to calculate the difference between two dates. It considers leap years, month lengths, and other calendar variations to ensure the age is accurate. The process usually involves:
- Accepting the date of birth (DOB) from the user.
- Taking the current date (or a custom "to-date").
- Calculating the time difference.
- Converting the result into years, months, and days.
