1 Frequently Asked Questions
Is the Pregnancy Due Date really free to use?

Yes, the Pregnancy Due Date is completely free to use. There are no hidden charges, no premium features locked behind paywalls, and no registration required. Simply visit the tool and start using it immediately.

How It Works

Enter the first day of your last menstrual period. The calculator applies Naegele's Rule (LMP + 280 days) to estimate your due date, and displays your current trimester and milestone dates.

WHO Recommended Parameters

The World Health Organization (WHO) recommends a minimum of 8 antenatal care contacts during pregnancy to reduce perinatal mortality and improve women's experience of care.

FAQs

How is the due date calculated?

Naegele's Rule: add 280 days (40 weeks) to the first day of your last menstrual period (LMP). This assumes a standard 28-day cycle. Your OB/GYN may adjust the date based on ultrasound measurements.

How accurate is an EDD?

Only about 5% of babies are born on their exact due date. Most births occur within 2 weeks before or after the EDD. An early ultrasound (before 14 weeks) provides the most accurate dating.

What is a trimester?

A pregnancy is divided into three trimesters: First (weeks 1–12), Second (weeks 13–26), Third (weeks 27–40+). Each trimester marks key developmental milestones.

Key Benefits

  • Supports LMP, conception, and ultrasound dates
  • Shows current trimester and weeks pregnant
