How do you calculate date of conception using due date?

To calculate the approximate date of conception using the due date, you can follow these steps:

1. Start with the due date. This is the date that your healthcare provider has estimated that you will give birth.

2. Subtract 266 days from the due date. This will give you an estimated date of conception.

It's important to note that this calculation is just an estimate, and the actual date of conception may vary. Factors such as the length of your menstrual cycle and the time of ovulation can affect the date of conception.

If you're trying to conceive or are interested in more accurate information about your date of conception, talk to your healthcare provider. They can provide you with guidance and resources to help you determine the best time to conceive.
