## Definition

A pregnancy calculator is a health utility that computes key milestones in a pregnancy, primarily estimating the expected date of delivery (EDD) and current gestational age. It dates the pregnancy from the first day of the last menstrual period (LMP) using Naegele's rule, or directly from the conception date. Gestational age is expressed in weeks and days to track fetal development. Expecting parents and healthcare providers use this tool to monitor trimester milestones, schedule prenatal appointments, and estimate the birth window.

## How to Use

1. **Select your input type** — Choose whether to calculate using your last menstrual period or conception date.
2. **Enter the reference date** — Input the first day of your last period or the date of conception.
3. **Review gestational details** — Check your estimated due date, current pregnancy week, and trimester breakdown.
