Having an accurate estimation of your delivery date allows you and your healthcare provider to monitor fetal development effectively. It serves as a benchmark for scheduling routine ultrasounds, blood work, and prenatal screenings. Keep in mind that only a small percentage of babies actually arrive precisely on their due date; most arrive within a two-week window before or after. This calculator simply gives you the most statistically accurate target to center your planning around.
This tool provides a standard estimate based on a regular 28-day menstrual cycle. Your healthcare provider may later adjust this date based on early ultrasounds, which can measure fetal growth more precisely.
If you have irregular periods, the standard calculation from your last menstrual period might be less accurate. In such cases, a professional ultrasound performed by a doctor is the best way to determine gestational age.
