Estimate your baby's arrival using Naegele's Rule.
A pregnancy due date calculator is one of the first and most exciting tools expectant parents use. Knowing your **estimated due date (EDD)** helps you plan for your baby's arrival, schedule prenatal appointments, and prepare for the journey ahead. Our online due date calculator provides a quick and easy way to get this crucial information.
This tool primarily uses Naegele's Rule, a standard method for calculating due dates based on the first day of your **Last Menstrual Period (LMP)**. The rule works by adding seven days to the first day of your LMP, subtracting three months, and then adding one year. For example, if your LMP was January 1, 2024, your estimated due date would be October 8, 2024. This simple calculation provides a reliable **pregnancy timeline**.
While the average **pregnancy length** is about 40 weeks from the LMP, it's important to remember that the **due date is an estimate**, and only about 4% of babies are born exactly on their due date. However, this Naegele's rule calculator offers a strong guideline for your **prenatal care schedule** and helps you track your baby's development. All your **calculated due dates** can be **saved locally** in your browser, allowing you to easily revisit them or track multiple pregnancies. Use this free online pregnancy tool for planning your **delivery date** and celebrating your **maternity journey**.
