How to Use the Baby Calculator in Months

Using our baby calculator in months is simple. Follow these steps:

Formula Used

The formula to calculate a baby's age in months is:

Age in Months = (Current Year - Birth Year) × 12 + (Current Month - Birth Month)

If the current day is before the birth day, subtract 1 month from the result.

This formula accounts for the full years and months between the birth date and the current date, providing an accurate measurement of your baby's age.

Example Calculation

Let's say your baby was born on January 15, 2022, and today is June 10, 2023.

  1. Calculate the difference in years: 2023 - 2022 = 1 year
  2. Convert years to months: 1 × 12 = 12 months
  3. Add the difference in months: 6 - 1 = 5 months
  4. Total months: 12 + 5 = 17 months

Since June 10 is after January 15, no adjustment is needed. Your baby is 17 months old.
