Due Date Calculator

An estimated due date (EDD) is a crucial part of your prenatal care. It marks the projected day of your baby's birth, guiding healthcare providers in monitoring foetal growth and scheduling important tests and scans. While it feels like a deadline, it is important to remember that it is only an estimate. Most babies arrive in the two weeks before or after their due date.

Our calculator offers several methods to determine your EDD. The most common is based on the first day of your last menstrual period (LMP), which is reliable for women with regular menstrual cycles. For those who know the exact date of conception, this method provides a more direct calculation. We also cater for assisted reproduction, with specific calculations for IVF transfers, and for dating based on early ultrasound measurements, which is often the most accurate approach.

Beyond just the due date, understanding your current gestational age (how many weeks pregnant you are) helps you follow your baby's development week by week. The journey is divided into three trimesters, each with unique milestones. Key dates, such as the 12 and 20-week scans, are vital for assessing the baby's health and development. Our calculator provides these key dates to help you plan and prepare for the exciting journey ahead.
