QUESTION POSED ON: 28 July 2003
I need to calculate the time difference between two dates in Formula language or LotusScript and then return the result in the format of "x months and y days." Do you know of any scripts or @Formulas that can do this?

I used a formula to calculate the difference. This does not include code for leap year and assumes that date1, the first date, is always earlier than date2. Here's the formula for a text field.

year1   := @IF(date1=""; 0; @Year(date1));
year2   := @IF(date2=""; 0; @Year(date2));
month1:= @IF(date1=""; 0; @Month(date1));
month2:= @IF(date2=""; 0; @Month(date2));
day1    := @IF(date1=""; 0; @day(date1));
day2    := @IF(date2=""; 0; @day(date2));
daysinmonth := @IF(date1=""; 
0;
@Select(month1;31;28;31;30;31;
30;31;31;30;31;30;31));
tempmonth:=@IF (year1=year2;
 month2 - month1;
 ((year2-year1)*12) + month2 - month1);
months:=@IF(day2<day1;
tempmonth - 1; 
tempmonth);
days:=@IF(day1<=day2;
 day2 - day1;
  daysinmonth + day2 - day1);
"sample: " + @text(months) + 
" months and " + @Text(days) + " days."
