To calculate E.D.D. you only have to enter the L.M.P. by choosing a date from the datepicker. It will also calculate the maturation by date. To calculate L.M.P. from E.D.D. you have to switch to the "Enter E.D.D." tab.
To calculate the maturity by U.S.G. you have to choose the U.S.G. date from the U.S.G. datepicker and enter the maturity at the time of U.S.G. in terms of weeks and days at the designated field.
When you enter the data the output is displayed automatically.
