Pregnancy Due Date Calculator

Calculate your estimated due date and track your pregnancy week by week. Choose from three calculation methods: last menstrual period, conception date, or ultrasound date. Once you have a target date, sync it with CalendarIQ for quick lookup of key prenatal appointments and explore CalendarCosmos if you love seeing celestial events that line up with your little one's arrival.

Select the first day of your last period to calculate your due date using Naegele's Rule.
