1. What is EDD Conception And?

The EDD Conception And method calculates the estimated due date by adding 266 days to the known conception date. This provides an accurate pregnancy timeline based on the actual date of conception.

2. How Does the Calculator Work?

The calculator uses the EDD Conception And formula:

Where:

• \( EDD \) — Estimated Due Date
• \( Conception Date \) — Known date of conception
• \( 266 days \) — Standard gestation period from conception

Explanation: This calculation assumes a standard 266-day gestation period from conception to delivery, which corresponds to approximately 38 weeks of pregnancy.

3. Importance of EDD Calculation

Details: Accurate due date estimation is crucial for prenatal care planning, monitoring fetal development, scheduling important tests, and preparing for delivery.

4. Using the Calculator

Tips: Enter the known conception date in the date field. The calculator will automatically compute the estimated due date by adding 266 days.

5. Frequently Asked Questions (FAQ)

Q1: Why 266 days specifically?
A: 266 days represents the average gestation period from conception to delivery, which equals 38 weeks of pregnancy.

Q2: How accurate is this method?
A: This method is highly accurate when the conception date is known with certainty, as it's based on the actual biological starting point of pregnancy.

Q3: What if I don't know my exact conception date?
A: If conception date is unknown, use the Last Menstrual Period (LMP) method which adds 280 days (40 weeks) to the first day of your last period.

Q4: Can the due date change during pregnancy?
A: While the calculated EDD provides a target, ultrasound measurements in early pregnancy may adjust the date based on fetal size and development.

Q5: What percentage of babies are born on their due date?
A: Only about 5% of babies are born exactly on their due date. Most are born within two weeks before or after the calculated date.
