Quick note on Naegele’s Rule.

Just a quick note on Naegele’s Rule.

Naegele’s Rule predicts an estimated due date based on the woman’s last menstrual period.  It does not account for leap years or months with less than 31 days.  Thus it will always be a few days off when doing the calculation or calculate out on a date that does not exist such as Feb 29 (except on leap year), Feb 30, Feb 31, Apr 31 June 31, Sept 31, Nov 31.
