## Quick Answer

Calculate your estimated baby due date and current weeks of pregnancy. You can estimate your due date using your last menstrual period, conception date, or IVF transfer date.

## Definition

A pregnancy due date calculator is an obstetrical tool that estimates the expected date of delivery (EDD) for a pregnant woman. It most commonly uses Naegele's rule, which adds 280 days (40 weeks) to the first day of the mother's last menstrual period (LMP). Alternatively, it can calculate the due date based on the known date of conception or ultrasound measurements.

## How to Use

1. **Choose a calculation method** — Select Last Menstrual Period (LMP), exact conception date, or IVF transfer date.
2. **Enter your date** — Input the corresponding date for your chosen calculation method.
3. **Read your due date** — View your estimated date of delivery (EDD), current trimester, and exact weeks of pregnancy.
