What you can do here get the difference between the 2 dates using timezone offset. something like below

private int getDSTdifferenceDateAdjustment(Date startDate, Date endDate, TimeZone timeZone)
{
    if (startDate == null || endDate == null) return 0;
    int baseOffset = timeZone.getOffset(startDate.getTime());
    int newOffSet = timeZone.getOffset(endDate.getTime());

    return (newOffSet - baseOffset);
}

Have something like this in your method

int dstDifference = getDSTdifferenceDateAdjustment(startdate, enddate, TimeZone.getDefault());
// The dstDifference will get in the negative, so we are adding to the dateRange variable
dateRange += dstDifference;

Try this one and even check when the DST starts next year. Mostly this will work in all these cases
