Last Menstrual Period (LMP): The user enters the first day of their last period, the most common starting point. Menstrual Cycle Length: By default 28 days, but users can adjust for longer or shorter cycles, which shifts the estimated ovulation date.

Once the data is entered, the calculator returns an estimated due date, a gestational age in weeks, and a range of possible delivery dates. It also flags dates that fall on weekends or holidays, allowing parents to plan around work schedules.

Accurately estimating a pregnancy’s due date is a cornerstone of prenatal care. A standard gestation period lasts roughly 280 days from the first day of the last menstrual period, yet variations in cycle length and ovulation timing can shift that window by weeks. A reliable, user‑friendly calculator that incorporates both cycle data and medical history can cut uncertainty, streamline appointments, and help parents feel more in control of their journey. For clinicians, an accurate due date informs scheduling for ultrasounds, screening tests, and delivery planning. For parents, it shapes budgeting, insurance arrangements, and emotional readiness. In a fast‑paced world, a simple tool that eliminates guesswork saves time, reduces anxiety, and aligns expectations between patient and provider.
