Hi,

It is very usefull script but still some problem is there.
when any end of month come in between start and ened day. it calculates wrong end date.
just check it with this.
document.write(days_between('31-08-2007', 3))
>>>> returns 4/9/2007 = wrong
document.write(days_between('31-08-2007', 4))
>>>> returns 5/9/2007 = wrong
document.write(days_between('02-08-2007', 2))
>>>> returns 3/8/2007 = right
