Let’s dive in.
What is a Pregnancy Due Date Calculator?
A Pregnancy Due Date Calculator is a simple digital tool that helps you estimate when your baby is likely to be born. It calculates your estimated date of delivery (EDD) based on the first day of your last menstrual period (LMP) or conception date.
Doctors usually use this same method to estimate due dates during your first prenatal visit.
Why is it Important to Know Your Due Date?
Knowing your due date helps you:
- Plan prenatal care visits properly
- Track pregnancy milestones
- Monitor fetal growth
- Prepare for maternity leave or delivery plans
- Avoid premature or post-term birth risks
It also helps doctors schedule scans, tests, and treatments accordingly.
How Does the Calculator Work?
Our tool is based on Naegele’s Rule, which estimates due date as:
Due Date = LMP + 280 days (or 40 weeks)
Some calculators also use conception date or ovulation date (if known), but LMP is the most commonly used.
Inputs Required:
- First Day of Last Menstrual Period (LMP)
- Or Date of Conception (Optional)
Outputs You Get:
- Estimated Due Date
- Current week of pregnancy
- Days left until delivery
