How Due Date Calculation Works
Pregnancy due dates are typically calculated using Naegele's Rule: Add 1 year, subtract 3 months, and add 7 days to the first day of your last menstrual period (LMP).
This calculation assumes a 28-day cycle with conception occurring on day 14. If your cycle is longer or shorter, the due date may be adjusted accordingly.
Only about 5% of babies are born on their exact due date, but 80% are born within 2 weeks of it.
