I have two dates in string format: xxxx-xx-xx
I want to be returned an INT that is the number of days between the two dates. Is there a simple function to do date subtraction and to convert the strings to the appropriate format?

this takes care of dates in the month, including leap years etc
<script>
var oDate_1 = new Date( 2003, 5, 15 )
var oDate_2 = new Date( 2003, 6, 12 )
iTime_1 = oDate_1.getTime();
iTime_2 = oDate_2.getTime();
iDiff = Math.abs( iTime_1 - iTime_2 );
alert( iDiff / 86400000 ) // 1000ms * 60secs * 60mins * 24hours = 1 day)
</script>
how do you want to pass the data in?
<script>
alert( getDaysBetween( "2003-5-15", "2003-6-12" ) );
function getDaysBetween( sDate_1, sDate_2 )
{
var aDate_1 = sDate_1.split( "-" );
var aDate_2 = sDate_2.split( "-" );
var oDate_1 = new Date( aDate_1[ 0 ], aDate_1[ 1 ], aDate_1[ 2 ] );
var oDate_2 = new Date( aDate_2[ 0 ], aDate_2[ 1 ], aDate_2[ 2 ] );
var iTime_1 = oDate_1.getTime();
var iTime_2 = oDate_2.getTime();
var iDiff = Math.abs( iTime_1 - iTime_2 );
var iDaysBetween = iDiff / 86400000;
return iDaysBetween;
}
</script>
or this if you want to pass in the pieces
alert( getDaysBetween( "2003", "5", "15", "2003", "6", "12" ) );
function getDaysBetween( iYear_1, iMonth_1, iDay_1, iYear_2, iMonth_2, iDay_2 )
{
var oDate_1 = new Date( iYear_1, iMonth_1, iDay_1 );
var oDate_2 = new Date( iYear_2, iMonth_2, iDay_2 );
var iTime_1 = oDate_1.getTime();
var iTime_2 = oDate_2.getTime();
var iDiff = Math.abs( iTime_1 - iTime_2 );
var iDaysBetween = iDiff / 86400000;
return iDaysBetween;
}

<script>
// yr m d

date1d=date1.split("-")
date1total=parseInt(date1d
date2d=date2.split("-")
date2total=parseInt(date2d
alert(date2total-date1tota
</script>
you will need to write some code to find out exactly how many days are in each different month, but you get the idea
