## Quick Answer

Estimate your baby's due date. Select your calculation method, enter the reference date, and view the estimated delivery date and gestational age.

## Definition

A due date calculator is a clinical tool used to project the expected date of birth for a child. It determines the date by adding two hundred eighty days to the mother's last menstrual period or two hundred sixty-six days to the conception date. This calculation assumes a regular cycle with ovulation occurring on day fourteen. The resulting date is an estimate, as natural delivery windows vary. Clinicians use it to date pregnancies and plan prenatal care schedules.

## How to Use

1. **Select dating parameter** — Choose Last Menstrual Period, conception date, or IVF transfer details.
2. **Enter the date** — Input the corresponding date into the calendar picker.
3. **Read the estimated due date** — View your estimated birth date, remaining days, and current weeks of gestation.
