Pregnancy Due Date Calculator - Weeks, Days & Trimester Tracker
Calculate your estimated due date (EDD) and track your pregnancy progress. Get accurate results based on your last menstrual period (LMP) or conception date. Most pregnancies last approximately 40 weeks (280 days) from the first day of the last menstrual period (LMP). Our calculator uses Naegele's Rule, which is the standard method used by healthcare providers. It adds 280 days to your LMP to estimate the day your baby will arrive.

Pregnancy Milestones
Planning for Baby
If your last period started on June 1st, your estimated due date would be March 8th of the following year. You would be in your second trimester by mid-September.
Tracking Milestones
At 20 weeks, you have reached the 'halfway' point of your pregnancy. This is often when the anatomy scan ultrasound is performed.
