1. What Is Weeks Pregnant Calculator By Due Date?

The Weeks Pregnant Calculator By Due Date estimates current pregnancy weeks based on the estimated due date and current date. This calculation helps track pregnancy progress and fetal development stages.

2. How Does The Calculator Work?

The calculator uses the pregnancy weeks formula:

\[ Weeks = 40 - \left\lfloor \frac{EDD - Current\ Date}{7} \right\rfloor \]

Where:

\( Weeks \) — Current pregnancy weeks
\( EDD \) — Estimated due date
\( Current\ Date \) — Today's date or specified date
\( \left\lfloor \right\rfloor \) — Floor function (rounds down to nearest integer)

Explanation: The formula calculates how many weeks remain until the due date and subtracts from the standard 40-week pregnancy duration.

3. Importance Of Pregnancy Week Calculation

Details: Accurate pregnancy week tracking is essential for monitoring fetal development, scheduling prenatal appointments, and preparing for delivery. It helps healthcare providers assess if the pregnancy is progressing normally.

4. Using The Calculator

Tips: Enter the estimated due date (usually provided by healthcare provider) and current date. The calculator will determine how many weeks pregnant you are based on the time remaining until delivery.
