How the Calculation Works

The calculation is based on the average pregnancy duration of 40 weeks (280 days). The formula used is:

Conception Date = Birth Date - Pregnancy Duration

Where:

Birth Date - The date when the baby was born
Pregnancy Duration - The average length of pregnancy (40 weeks)

The calculator subtracts the pregnancy duration from the birth date to estimate the conception month.

Worked Example

Let's say a baby was born on June 15, 2023. Using a standard pregnancy duration of 40 weeks (280 days):

Conception Date = June 15, 2023 - 280 days Conception Date ≈ September 16, 2022

Therefore, the estimated month of conception would be September 2022.
