Formula Used
The baby age calculator uses the following formula to calculate the age in weeks and days:
Total Days = Current Date - Date of Birth
Weeks = Total Days ÷ 7
Days = Total Days mod 7
This formula ensures accurate results by considering the exact number of days between the two dates and then converting that into weeks and remaining days.
Example Calculation
Let's say your baby was born on January 15, 2023, and today is March 15, 2023. Here's how the calculation works:
Date of Birth: January 15, 2023
Current Date: March 15, 2023
Total Days: 60 days
Weeks: 8 weeks (60 ÷ 7 = 8)
Days: 4 days (60 mod 7 = 4)
Result: 8 weeks and 4 days
This example shows that your baby is 8 weeks and 4 days old as of March 15, 2023.
