The Chronological Age Calculator is a simple tool that helps you determine a person’s exact age in years, months, and days based on their birth date and a selected reference date (usually today’s date).
How to Use
Enter Your Birth Date: Input your full date of birth (day, month, and year).
Enter Today’s Date (or a Target Date): By default, the calculator uses the current date, but you can input any future or past date for different calculations.
Calculate: The tool instantly computes:
Your chronological age (years, months, and days).
The total number of days you have lived.
The total number of months you have lived (approximate).
Days remaining until your next birthday.
