This pregnancy due date calculator gives you an easy and reliable way to estimate when your baby might arrive. You can use the date of your last menstrual period (LMP) or the date of conception if you know it. Typically, pregnancy lasts about 40 weeks (280 days) from your LMP, or 38 weeks (266 days) from conception.
By entering your LMP or conception date, this calculator instantly provides your estimated due date, helping you plan prenatal care, baby shopping, and preparations for welcoming your new family member.
Knowing your due date is one of the most exciting parts of pregnancy. It helps you monitor your pregnancy stages, schedule doctor visits, prepare for childbirth, and arrange maternity leave. It also gives you an idea of your baby's development milestones each week.
If you've already received an estimated due date from your doctor or ultrasound technician, select "Known Due Date" above. The calculator will work backwards to show the conception window and how far along you are today.
Many expectant parents rely on this simple yet essential tool as part of their pregnancy journey.
Your calculated due date represents an estimated timeframe when your baby is likely to be born. While exact dates are rare—only about 4% of babies arrive precisely on their due dates—the calculator provides a helpful reference point.
This tool also shows you how many weeks and days pregnant you are right now, giving you real-time updates on your pregnancy progress.
The calculator is highly reliable, using a method widely recognized by healthcare professionals. However, actual delivery dates vary naturally. Early ultrasounds, performed by your healthcare provider, may provide more precise due date estimates.
Always consult your doctor for professional pregnancy care, guidance, and personalized advice.
This calculator is perfect for expectant parents, healthcare providers, midwives, and anyone preparing for pregnancy or childbirth. It’s a must-have tool on pregnancy-related websites due to its simplicity, accuracy, and relevance to expecting mothers.
Regularly checking your due date and pregnancy progress helps you stay informed, excited, and prepared throughout your pregnancy.
