How the Baby Age Calculator Works

The baby age calculator uses a simple date difference calculation to determine your child's age. Here's how it works:

Age in years = Current year - Birth year Age in months = (Current year - Birth year) × 12 + (Current month - Birth month) Age in weeks = (Current date - Birth date) / 7 Age in days = Current date - Birth date

The calculator accounts for leap years and varying month lengths to provide an accurate age calculation.

Note: The calculator assumes the current date is after the birth date. If you enter a future date, the calculator will display an error message.
