Conception Date Calculator: Find Your Estimated Conception Date

To calculate the conception date, we need to count back 280 days (the average gestation period) from the due date.

1. Due date: April 1, 2023

2. Count back 280 days

Conception Date: June 23, 2022

So if you are expecting a baby with due date of April 1, your conception date would be around June 23, 2022.
