1. What is Pregnancy Calculator Off Conception Date?

The Pregnancy Calculator Off Conception Date calculates gestational age in weeks based on the conception date. It provides an accurate method for determining how many weeks pregnant a person is from the actual date of conception.

2. How Does the Calculator Work?

The calculator uses the pregnancy weeks formula:

\[ WP = \lfloor \frac{CD - CPD}{7} \rfloor \]

Where:

\( WP \) — Weeks pregnant (weeks)
\( CD \) — Current date (date)
\( CPD \) — Conception date (date)
\( \lfloor \rfloor \) — Floor function (rounds down to nearest integer)

Explanation: The formula calculates the number of full weeks that have passed since conception by dividing the total days by 7 and rounding down to the nearest whole number.

3. Importance of Pregnancy Dating

Details: Accurate pregnancy dating is crucial for monitoring fetal development, scheduling prenatal care, determining due dates, and making important medical decisions throughout pregnancy.
