How Conception Calculations Work

Pregnancy duration is typically measured from the first day of the last menstrual period (LMP) to the due date. The average pregnancy lasts 40 weeks (280 days).

Formula: Due Date = Last Menstrual Period + 280 days

Conception Date: Conception Date = Due Date - 280 days

Baby's Age: Baby's Age = Current Date - Conception Date

These calculations help you understand your baby's development stages and track your pregnancy timeline.

Example Calculation

Let's say your last menstrual period was on January 1, 2023. Here's how the calculation works:

Due Date: January 1, 2023 + 280 days = October 8, 2023
Conception Date: October 8, 2023 - 280 days = January 1, 2023
If today is May 1, 2023, your baby's age would be 4 months and 1 day.

This example shows how the calculator helps you track your pregnancy timeline and understand your baby's development stages.
