Explanation: This calculation determines how many days remain until you reach 40 weeks of pregnancy and adds that duration to your current date.
Details: Knowing your estimated due date helps in planning prenatal care, preparing for delivery, and monitoring fetal development milestones throughout your pregnancy journey.
Tips: Enter your current date, select your current pregnancy duration in weeks (0-40) and additional days (0-6). The calculator will provide your estimated due date based on a standard 40-week pregnancy.
Q1: How Accurate Is This Due Date Calculation?
A: This calculation provides an estimate based on standard pregnancy duration. Actual delivery dates may vary by ±2 weeks from the estimated due date.
Q2: What If I Know My Conception Date?
A: If you know your conception date, you can calculate due date by adding 38 weeks (266 days) to that date for potentially more accurate results.
Q3: Why Is Pregnancy Calculated From Last Menstrual Period?
A: Pregnancy is typically calculated from the first day of your last menstrual period (LMP) because this date is usually more certain than conception date.
Q4: Can My Due Date Change During Pregnancy?
A: Yes, healthcare providers may adjust your due date based on ultrasound measurements, especially if there's a significant difference from LMP-based calculations.
Q5: What Percentage Of Babies Are Born On Their Due Date?
A: Only about 5% of babies are born exactly on their due date. Most births occur within two weeks before or after the estimated due date.
