1. What Is The Pregnancy Weeks Calculator?

The Pregnancy Weeks Calculator estimates how many weeks pregnant you are based on your estimated due date (EDD) and current date. This calculation helps track pregnancy progress and fetal development stages.

2. How Does The Calculator Work?

The calculator uses the standard pregnancy calculation formula:

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

Where:

\( Weeks \) — Number of weeks pregnant
\( EDD \) — Estimated Due Date
\( Current\ Date \) — Today's date or specified date
\( 40 \) — Standard full-term pregnancy duration in weeks
\( \left\lfloor \right\rfloor \) — Floor function (rounding down)

Explanation: The formula calculates how many weeks remain until the due date and subtracts from 40 weeks (full term) to determine current pregnancy week.

3. Importance Of Pregnancy Week Calculation

Details: Accurate pregnancy week calculation is essential for monitoring fetal development, scheduling prenatal appointments, preparing for delivery, and understanding which developmental milestones to expect.

4. Using The Calculator

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