1. What Is Due Date Calculator By Weeks?

The Due Date Calculator By Weeks estimates the expected delivery date (EDD) based on current pregnancy weeks. It calculates how many weeks remain until the standard 40-week gestation period and projects the due date accordingly.

2. How Does The Calculator Work?

The calculator uses the due date formula:

\[ EDD = Current Date + (40 - Current Weeks) \times 7 \text{ days} \]

Where:

\( EDD \) — Estimated Due Date
\( Current Date \) — Today's date or specified date
\( Current Weeks \) — Current pregnancy weeks (0-40)
\( 40 \) — Standard full-term pregnancy duration in weeks
\( 7 \) — Days per week conversion factor

Explanation: The formula calculates remaining weeks until full term and converts them to days, then adds those days to the current date to determine the estimated due date.

3. Importance Of Due Date Calculation

Details: Accurate due date estimation is crucial for prenatal care planning, monitoring fetal development milestones, scheduling important tests, and preparing for delivery. It helps healthcare providers track pregnancy progress and identify potential complications.

4. Using The Calculator

Tips: Enter the current date (or any reference date) and current pregnancy weeks (0-40). The calculator will compute your estimated due date. For most accurate results, use the date from your last menstrual period or early ultrasound dating.
