The EDD calculator is a nifty little utilty to calculate the expected date of delivery from the last menstrual period date. It is extremely simple to use. Just input the date of the first day of the last menstrual period in the left hand box (remember to format the date as indicated eg.28 -02 -09) and the expected date of delivery will immediately be displayed in the right hand box. Please note that this date is an estimation and the actual date may vary in some cases. |
