Pregnancy is a transformative journey, and one of the first questions expectant parents often have is: "When will our baby arrive?" A day of birth calculator pregnancy, more commonly known as a pregnancy due date calculator, is a tool designed to estimate this special date.

These calculators typically use one of several methods to determine your estimated due date (EDD):
- Last Menstrual Period (LMP): This is the most common method. The calculator adds 280 days (40 weeks) to the first day of your last normal menstrual period.
- Conception Date: If you know the exact date of conception, the calculator adds 266 days (38 weeks) to this date.
- IVF Transfer Date: For pregnancies achieved through in vitro fertilization (IVF), the transfer date of the embryo is used, with the appropriate number of days added based on whether it was a day-3 or day-5 transfer.
- Ultrasound: An early ultrasound can provide a more accurate gestational age, especially if your periods are irregular.
Our Pregnancy Calculator supports all the methods mentioned above to provide you the best estimation.
Factors Affecting Due Date Accuracy
While a day of birth calculator pregnancy provides an estimate, it's important to remember that very few babies are born exactly on their due date. Several factors can influence the actual delivery date:
- Cycle Length: The standard calculation assumes a 28-day cycle. If your cycle is shorter or longer, the due date may need adjustment.
- Irregular Periods: Irregular cycles make it harder to pinpoint ovulation and conception, impacting due date accuracy.
- First-Time Pregnancy: First-time mothers tend to carry slightly longer.
- Multiple Pregnancies: Women carrying twins or more are more likely to deliver preterm.
