A birthday conception calculator, also known as a reverse due date calculator, is a tool that estimates the date on which a pregnancy was conceived, based on the known or expected birth date (due date). It essentially works backward from the due date to determine the approximate date of conception.

There are several reasons why someone might want to use a birthday conception calculator:

How Does Our Birthday Conception Calculator Work?
Our Pregnancy Calculator & Ovulation Estimator offers dual functionality: it can be used as a standard pregnancy calculator or as a birthday conception calculator to estimate your conception date. Here's how it works:
- Input: You provide either a known due date or a past birth date.
- Calculation: The calculator subtracts 266 days (38 weeks) from the provided date. This is based on the average gestation period from conception to birth.
- Result: The calculator then displays the estimated date of conception.
Factors Affecting Accuracy
It's important to remember that a birthday conception calculator provides an *estimation*. Several factors can influence the accuracy of the results:
- Gestation Length: The calculator uses an average gestation period. However, some pregnancies are shorter or longer, affecting the estimated conception date.
- Irregular Cycles: Women with irregular menstrual cycles may find the estimation less precise.
- Premature Birth: Babies born prematurely will skew the conception date calculation. Make sure to indicate a full-term pregnancy with the calculator's options to more accurately track the conception date.
