EDD Calculator – Estimated Date of Delivery
About
The Estimated Date of Delivery (EDD) is a crucial date for expecting parents. This date tells you when your baby is likely to be born and is calculated based on the first day of your last menstrual period (LMP) or the date of conception. Many factors can influence the accuracy of the EDD, but a well-informed calculation can help you prepare for one of the most exciting moments in life.
How to Use the EDD Calculator
Using an EDD calculator is straightforward and can be done online or through various mobile applications. Follow these simple steps:
- Input your information: Enter the first day of your last menstrual period or the date of conception.
- Select your preferences: Some calculators may ask you to specify whether you have regular menstrual cycles to improve accuracy.
- Calculate: Click the “Calculate” button to find your estimated delivery date.
Formula
The formula used for calculating the EDD generally follows the rule of adding 280 days (or 40 weeks) to the first day of your last menstrual period. This is based on the average length of a pregnancy:
EDD = LMP + 280 days
Example Calculation
Let’s say the first day of your last menstrual period was January 1, 2023:
- LMP: January 1, 2023
- Add 280 days: January 1, 2023 + 280 days = October 7, 2023
Your estimated date of delivery would be October 7, 2023.
Limitations
While the EDD calculator is a helpful tool, its accuracy depends on various factors:
- Irrregular menstrual cycles: Women with irregular cycles may find their EDD less predictable.
- Medical conditions: Certain health issues can impact the length of pregnancy.
- Ultrasound findings: If available, ultrasounds can offer more reliable estimates than calculations based strictly on LMP.
Tips for Managing Your Pregnancy Countdown
As you await your little one’s arrival, consider these tips for managing the time effectively:

- Attend prenatal classes: Knowledge is key, and prenatal classes can help you feel more prepared.
