Pregnancy Due Date Calculator
Estimate your due date, current week of pregnancy, and trimester using your last period, conception date, or a known due date. This gives you an estimate to plan around, not a fixed delivery date.
Key Pregnancy Milestones
General timeline benchmarks most pregnancies are measured against
End of First Trimester
Miscarriage risk drops significantly after this point, and many parents share their news around this stage.
Anatomy Scan
A detailed ultrasound typically checks fetal development and organ growth, and can often reveal the baby's sex.
Viability Milestone
Often cited as the point where survival outside the womb becomes possible with intensive medical care, should early delivery occur.
Third Trimester Begins
Growth accelerates and appointments typically become more frequent from this stage onward.
Full Term
A baby born from this point on is generally considered full term rather than preterm.
Estimated Due Date
Only a small share of babies actually arrive on this exact date. Delivery anytime from week 37 to 42 is considered typical.
This calculator provides an estimate based on standard averages and does not account for individual variations in cycle length, ovulation timing, or pregnancy progression. It is not a substitute for medical care. Please confirm your due date and monitor your pregnancy with a qualified doctor, especially since dating can shift after an early ultrasound.
