Pregnancy Due Date Calculator

Estimate your baby’s due date based on your last menstrual period or conception date.

What is a Pregnancy Due Date Calculator?

A pregnancy due date calculator helps estimate the expected delivery date (EDD) of your baby. It typically uses the first day of your last menstrual period (LMP) or the conception date to calculate when your baby is likely to be born.

How Due Date is Calculated

Most due date calculations are based on a standard pregnancy duration of 40 weeks (280 days). The most common method is Naegele’s Rule, which adds 280 days to the first day of your last menstrual period.

  • Due Date = LMP + 280 days (40 weeks)

Why Knowing Your Due Date is Important

Knowing your due date helps you track pregnancy milestones, schedule medical check-ups, and prepare for delivery. It also allows healthcare providers to monitor your baby’s growth and development effectively.

Benefits of Using a Due Date Calculator

  • ✔ Estimate your baby’s expected delivery date
  • ✔ Track pregnancy weeks and trimesters
  • ✔ Plan prenatal care and doctor visits
  • ✔ Prepare for labor and delivery
  • ✔ Understand fetal development stages

Pregnancy Trimesters

  • First Trimester: Weeks 1 to 12
  • Second Trimester: Weeks 13 to 26
  • Third Trimester: Weeks 27 to 40

Each trimester represents a different stage of your baby’s development and changes in your body.

How Accurate is the Due Date?

The due date is an estimate, not an exact prediction. Only a small percentage of babies are born on their exact due date. Most deliveries occur within a week before or after the estimated date.

Common Use Cases

  • Planning prenatal care
  • Tracking pregnancy progress
  • Preparing for childbirth
  • Scheduling medical checkups
  • Monitoring baby development
