As a result, it provides a highly detailed and remarkably precise age calculation for both personal and professional use.

How It Works:

• Input: The user provides their date of birth and optionally a future or current date.
• Output: The calculator returns the person’s age in years, months, days, as well as additional metrics like total weeks, days, hours, minutes, and seconds.

Important Calculations:

• Years: Calculated as the difference between the current year and the birth year.

• Months: Adjusted based on whether the current date falls before or after the birth date within the year.

• Days: Determined by checking if the current day is before or after the birth day in the current month.

• Total Time: Additionally, the calculator can break the age down into total weeks, months, days, and even into hours, minutes, and seconds.
