So, how old are you exactly?

How do I calculate age in years, months, and days?
To calculate someone’s age in years, months, and days:

Find the differences between the person’s birth year/month/day and the current year/month/day:
years = birth_year – current_year;
months = birth_month – current_month; and
day = birth_day – current_day.
Replace them in the following formula: age = (years × 365) + (months × 31) + days.
Divide the result by years from step 1 and truncate it to get the age in years.
Multiply the remainder of step 3 by 12 and truncate it to get the months.
Multiply this last remainder by 31 to get the days.

Was that simple!?
