1. What Is Conception Date Calculation?

The conception date calculation estimates when fertilization likely occurred based on your estimated due date. This calculation uses the standard pregnancy timeline of 266 days from conception to due date.

2. How Does The Calculator Work?

The calculator uses the simple formula:

Where:

• \( EDD \) — Estimated Due Date
• \( 266 days \) — Standard gestation period from conception to birth

Explanation: This calculation assumes a typical 38-week (266-day) gestation period from conception to estimated due date.

3. Importance Of Conception Date

Details: Knowing your estimated conception date helps track pregnancy milestones, understand fetal development stages, and provides insight into your pregnancy timeline.

4. Using The Calculator

Tips: Enter your estimated due date in the date field. The calculator will automatically compute your estimated conception date by subtracting 266 days from your due date.

5. Frequently Asked Questions (FAQ)

A: 266 days represents the typical gestation period from conception to birth, which is approximately 38 weeks or 9.5 lunar months.

Q2: How accurate is this calculation?
A: This provides an estimate. Actual conception dates can vary due to individual differences in gestation periods and ovulation timing.

Q3: What if I know my last menstrual period (LMP)?
A: Conception typically occurs about 14 days after the first day of your last menstrual period in a regular 28-day cycle.
