Truncate((GetAsNumber(Get(CurrentDate)) - GetAsNumber(date))/7;0) & " " & "week(s)" & " " & ((GetAsNumber(Get(CurrentDate))-GetAsNumber(date))/7-Truncate((GetAsNumber(Get(CurrentDate))-GetAsNumber(date))/7;0))*7 & " " & "day(s)" Click to copy

May be useful for developing solutions in healthcare. Uses last menstrual period ("date") to determine the # of weeks and days since last menstrual period and the current system date. It reports the interval in weeks and days. Easily modifiable to calculate using any date, not just Get(CurrentDate). Sorry if I did not follow the filemaker convention in formula notation.
