Pregnancy Calculator
Calculate Your Due Date
What is a Pregnancy Calculator?
A pregnancy calculator helps you estimate the due date of your baby based on the first day of your last menstrual period (LMP). It provides an estimated due date to help you plan for the arrival of your baby.
How Does it Work?
Our pregnancy calculator uses the first day of your last menstrual period (LMP) and adds 280 days (40 weeks), which is the average length of a pregnancy. Enter the date of your LMP to find out your estimated due date.
