Example Calculation

Let's look at an example to understand how the baby birthday calculator works.

Suppose your baby was born on January 15, 2022, and today is June 1, 2023. Here's how the calculation would work:

Current Date: June 1, 2023 Birth Date: January 15, 2022 Age = June 1, 2023 - January 15, 2022

The calculator would determine that the baby is 1 year, 4 months, 2 weeks, and 4 days old.
