First, extract the birthdate and current date components (year, month, day). Then, calculate the difference in years, months, and days. Adjust the calculation if the day of the birth month is greater than the current day.

Here's a Python code example:

from datetime import date

def calculate_age(birthdate):
    today = date.today()
    
    years = today.year - birthdate.year
    months = today.month - birthdate.month
    days = today.day - birthdate.day
    
    # Adjust if current day is less than birthdate day
    if days < 0:
        months -= 1
        # Calculate days in previous month
        last_month = today.month - 1 if today.month > 1 else 12
        last_month_year = today.year if today.month > 1 else today.year - 1
        days_in_last_month = (date(last_month_year, last_month + 1, 1) - date(last_month_year, last_month, 1)).days
        days += days_in_last_month
    
    # Adjust if current month is less than birthdate month
    if months < 0:
        years -= 1
        months += 12
    
    return years, months, days

# Example usage
birthdate = date(1990, 5, 15)  # Replace with the actual birthdate
age = calculate_age(birthdate)
print(f"Age: {age[0]} years, {age[1]} months, {age[2]} days")

In this code, we first import the date class from the datetime module to handle date objects. Then, we define the calculate_age function, which takes a birthdate as input. We get today's date using date.today() and calculate the difference in years, months, and days between today’s date and the birthdate. Adjustments are made if the current day is less than the birthdate day by subtracting one month and adding the correct number of days from the previous month. Similarly, if the current month is less than the birthdate month, we subtract one year and add the correct number of months.

I hope this is what you're looking for, or at least something similar.
