1. What is Pregnancy Week By Week Calculator?

The Pregnancy Week By Week Calculator estimates the current week of pregnancy based on the estimated due date and current date. It helps expectant mothers track their pregnancy progress and understand fetal development milestones.

2. How Does the Calculator Work?

The calculator uses the pregnancy week calculation formula:

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

Where:

\( EDD \) — Estimated Due Date
\( Current\ Date \) — Today's date or any 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 that from the standard 40-week pregnancy duration.

3. Importance of Pregnancy Week Tracking

Details: Accurate pregnancy week tracking is essential for monitoring fetal development, scheduling prenatal appointments, preparing for delivery, and understanding appropriate developmental milestones.

4. Using the Calculator

Tips: Enter the estimated due date provided by your healthcare provider and the current date. The calculator will determine your current pregnancy week based on the standard 40-week pregnancy model.
