1. What is Pregnancy Month Calculator?

The Pregnancy Month Calculator estimates the current month of pregnancy based on the conception date and current date. It provides an accurate assessment of pregnancy progression using standardized calculations.

2. How Does the Calculator Work?

The calculator uses the pregnancy month formula:

\[ M = \left\lfloor \frac{(CD - CPD)}{7 \times 4.345} \right\rfloor + 1 \]

Where:

\( M \) — Months pregnant (months)
\( CD \) — Current date (date)
\( CPD \) — Conception date (date)
\( 7 \) — Days per week
\( 4.345 \) — Average weeks per month

Explanation: The formula calculates the difference between current date and conception date in days, converts to weeks, then to months using the average weeks per month, and adds 1 to account for the starting month.

3. Importance of Pregnancy Month Calculation

Details: Accurate pregnancy month calculation is crucial for tracking fetal development, scheduling prenatal appointments, preparing for delivery, and monitoring maternal health throughout pregnancy.

4. Using the Calculator

Tips: Enter the conception date and current date in the format YYYY-MM-DD. Ensure both dates are valid and the current date is after the conception date for accurate results.

5. Frequently Asked Questions (FAQ)
