How do I calculate my due date?

Your due date is calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP). According to the American College of Obstetricians and Gynecologists, this method is accurate for 95% of pregnancies. Our free due date calculator does this calculation instantly.

What is an EDD calculator?

An EDD (Expected Delivery Date) calculator is a tool that predicts when your baby will be born. It uses the Naegele's rule: take the first day of your last period, add 7 days, then add 9 months. Studies show only 4-5% of babies are born on their exact due date, but 80% arrive within 2 weeks of the EDD.

How accurate is a contraction timer?

Digital contraction timers are highly accurate for tracking labor progress. The 5-1-1 rule suggests going to the hospital when contractions are 5 minutes apart, lasting 1 minute each, for 1 hour. Our free contraction counter helps you track this pattern precisely.

How much does it cost to have a baby?

According to 2024 data, the average first-year cost of having a baby ranges from $12,000-$23,000 in the USA, £8,000-£15,000 in the UK, $10,000-$20,000 CAD in Canada, and $15,000-$25,000 AUD in Australia. Use our baby cost calculator for a detailed breakdown by country.
