EDD calculator will help you to know the Expected date of your delivery based on your last menstrual period.
Just stational age means today how far you are in your pregnancy. Your doctor may use gestational age in weeks rather than months to plan the care during your antenatal period. Most of the pregnancies last for 40 weeks from the last menstrual period.
To calculate your estimated due date and the stational age you need to enter the current date and the date of your last menstrual period.
