Introduction to Due Date Calculator
A Due Date Calculator is a specialized tool designed to calculate an estimated due date for pregnancy based on the first day of a woman's last menstrual period (LMP). This tool is widely used by expectant parents, healthcare professionals, and researchers to estimate the expected date of delivery (EDD) or due date, providing valuable information throughout pregnancy.
How Does a Due Date Calculator Work?
Due Date Calculators typically use a formula known as Naegele's Rule to estimate the due date. The calculation is based on adding 280 days (or 40 weeks) to the first day of the woman's last menstrual period. This method assumes a regular menstrual cycle of 28 days with ovulation occurring on day 14.
Naegele's Rule: EDD = LMP + 280 days
It's important to note that while this calculation provides an estimated due date, actual delivery dates can vary, and healthcare providers may adjust the due date based on ultrasound examinations and other factors.
