According to YourDueDate.com,
Your due date is calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (assuming a 28 day cycle).
Note that your menstrual period and ovulation are counted as the first two weeks of pregnancy. If you deliver on your due date, your baby is actually only 38 weeks old, not 40.
According to BabyCentre,
Unless you’ve been tracking your ovulation, there’s no way to know for sure exactly when you ovulated and conceived. That’s why your due date is calculated based on the date of your last period instead.

Knowing your due date for when the baby is to be born is very crucial. It helps you prepare your body, mind and soul as the date approaches. It projects the future before you in a granular and mega way in getting whatever primary needs of the soon to come baby in place.
I advice all pregnant women to always have an estimated due date for their baby at heart at the very least. Cheers too because it is not easy being a mom beginning from conception.
