Naegele's Rule: EDD = LMP + 280 days (40 weeks), adjusted for cycle length variations from 28 days. Ultrasound dating in the first trimester is the most accurate method and takes priority over LMP-based calculation.
1st trimester: Weeks 1–12 | 2nd trimester: Weeks 13–27 | 3rd trimester: Weeks 28–40+
