The formula to calculate the Expected Date of Delivery (EDD) using Naegele's Rule is:

Where:
Naegele's Rule is a standard method used by obstetricians to estimate a pregnant woman's due date. The rule calculates the expected date of delivery by adding one year, subtracting three months, and adding seven days to the first day of a woman's last menstrual period. This method assumes a 28-day menstrual cycle with ovulation occurring on the 14th day, and a standard gestation period of 280 days from the last menstrual period to the birth of the baby.
