Ever wondered when you were conceived? A reverse birth date calculator, also known as a conception calculator, helps you estimate the date of conception based on a known or estimated due date. It works backward from your due date to give you a likely timeframe for when conception occurred.

Calculate Your Conception Date →Why Use a Reverse Birth Date Calculator?
There are several reasons why you might want to use a reverse birth date calculator:
- Nostalgia: Perhaps you're curious about the circumstances surrounding your conception or that of a loved one.
- Planning: If you're trying to conceive and want your baby to be born during a specific month, this calculator can help you determine the ideal time to try.
- Accuracy: If you know your due date from an early ultrasound, using a reverse birth date calculator can help you estimate your conception date more accurately than relying solely on your last menstrual period.
How Does a Reverse Birth Date Calculator Work?
The basic principle behind a reverse birth date calculator is simple math. It subtracts the average length of a pregnancy (280 days or 40 weeks) from the due date to estimate the conception date. However, it's essential to remember that this is just an estimation.
Our comprehensive Pregnancy Calculator & Ovulation Estimator uses your due date to give you a range of possible conception dates. It also helps you determine your fertile window, giving you even more insight into your reproductive health planning. Head over to our calculator to use it.
Factors Affecting Conception Date Accuracy
Several factors can influence the accuracy of a reverse birth date calculator's results:
- Cycle Length: The calculator assumes a standard 28-day menstrual cycle. If your cycle is significantly shorter or longer, the results might be less accurate.
- Ovulation Timing: Ovulation typically occurs around 14 days before your next period. However, this can vary, making the conception date estimation less precise.
- Sperm Viability: Sperm can survive for up to 5 days in the female reproductive tract. This means that conception can occur several days after intercourse.
