Due Date Calculation:
From: | To: |
The Due Date Gestation Calculator estimates the expected delivery date based on the conception date and average gestation period. This helps healthcare providers and expectant parents plan for the arrival of a newborn.
The calculator uses a simple formula:
Where:
Explanation: The calculation adds the gestation period (in days) to the conception date to determine the estimated due date.
Details: Accurate due date estimation is crucial for prenatal care, monitoring fetal development, and planning for delivery. It helps identify potential preterm or post-term pregnancies.
Tips: Enter the known or estimated conception date and the gestation period in days. The default gestation period is 280 days (40 weeks) which is average for humans.
Q1: What's the difference between conception date and LMP date?
A: Conception date is when fertilization occurs (about 2 weeks after the first day of the last menstrual period for women with regular cycles).
Q2: What is the average human gestation period?
A: The average is 280 days (40 weeks) from the first day of the last menstrual period, or 266 days (38 weeks) from conception.
Q3: How accurate is this calculation?
A: While it provides a good estimate, only about 5% of women deliver on their exact due date. Most deliver within 2 weeks before or after.
Q4: What factors can affect gestation length?
A: Factors include maternal age, health conditions, number of previous pregnancies, and whether it's a multiple pregnancy.
Q5: Should I use this for medical decisions?
A: This calculator provides estimates only. Always consult with your healthcare provider for medical decisions regarding pregnancy.
