Formula Used

The exact baby age is calculated by determining the difference between the current date and the baby's birth date, then breaking down that difference into years, months, weeks, and days.

Age in years = Current year - Birth year Age in months = (Current year - Birth year) × 12 + (Current month - Birth month) Age in weeks = (Total days between dates) ÷ 7 Age in days = Total days between dates

This calculation accounts for varying month lengths and leap years to provide the most accurate result possible.
