[flexcoders] Difference between two dates

Daniel Tuppeny Fri, 23 Jun 2006 07:21:59 -0700

I'm struggling to get the difference between two dates in months...

I want to input something like Jan 1st and July 18th, and get something like 7.5 out.

I tried using .getTime() and then creating a date from the result, but that's not accurate because of variable length months. I then wrote the below, but it only works for whole months (and I need decimals).

It would've taken me seconds in C# (DateTime - DateTime = Timespan), but I can't find any useful methods in Flex. Am I missing something simple?

if (startDate > endDate)
   {
    var tmp:Date = endDate;
    endDate = startDate;
    startDate = endDate;
   }

   var numMonths:Number = 0;

   while (startDate <= endDate)
   {
    numMonths++;
    trace(startDate.month);
    if (startDate.month == 12)
    {
     trace("reset");
     startDate.fullYear++;
     startDate.month -= 12;
    }
    else
     trace("inc");
     startDate.month++;
   }

   return numMonths;
