Subtracting day from current date.

[dinoviapangea]

I'm trying to subtract one day from thet current date. My code is as follows:

function howlong(arg) {
if (length(arg)==1) {
arg = "0" + arg;
return arg;
}
else {
arg = arg;
return arg;
}
}
myDate = new Date();
dd = myDate.getDate()-1;
mm = myDate.getMonth();
yy = myDate.getFullYear();
switch (mm) {
case 0: mm = "Jan";
break;
case 1: mm = "Feb";
break;
case 2: mm = "Mar";
break;
case 3: mm = "Apr";
break;
case 4: mm = "May";
break
case 5: mm = "Jun";
break;
case 6: mm = "Jul";
break
case 7: mm = "Aug";
break
case 8: mm = "Sep";
break
case 9: mm = "Oct";
break
case 10: mm = "Nov";
break
case 11: mm = "Dec";
break
}
textdate = ( dd + " " + mm + " " + yy)

Worked fine until today, because it now shows May 0, 2003 for the yesterday. Any help would be appreciated.

Thanks

i would just scrap your code even though it looks ok and use this tried and trusted method
