(xyphoid process). Ultrasound can be used to determine gestational age. Measurement of a crown-rump length during the first trimester (1-13 weeks) will give a gestational age that is usually accurate to within 3 days of the actual due date.During the second trimester (14-28 weeks), measurement of the biparietal diameter will accurately predict the due date within 10-14 days in most cases.n real life, determining gestational age can be challenging. The estimated delivery date is calculated by adding 280 days to the first day of the last menstrual period. An alternative method of determining the due date is to add 7 days to the LMP, subtract three months, and add one year.
