本文介绍了使用C#、PHP和Java三种编程语言计算两个日期之间的年龄、月份和天数差的方法。通过比较月份和天数来精确计算，适用于各种需要日期计算的场景。

c#:

 DateTime startDate = new DateTime();
            DateTime endDate = new DateTime();

            int age =0;
            int month = 0;
            int day = 0;
         
            if (endDate.Month>startDate.Month)
            {
                age = endDate.Year - startDate.Year;
                month = endDate.Month - startDate.Month;
            }
            else 
            {
                age = endDate.Year - startDate.Year-1;
                month =12+ endDate.Month - startDate.Month;
            }

            if (endDate.Day>startDate.Day)
            {
                day = endDate.Day - startDate.Day;
            }
            else
            {
                //上个月天数-startDate.Day+endDate.Day
                day = (endDate-endDate.AddMonths(-1)).Days  - startDate.Day+endDate.Day;
                month--;
            }
            Response.Write(string.Format("{0}岁{1}月{2}天", age, month, day));

php:

        $age=0;
        $month=0;
        $day=0;

            $day = date('j',$endDate)-date('j',$startDate);
        }else{
            $day= date('t',strtotime('-1 Month',$endDate))-date('j',$startDate)+date('j',$endDate);
            $month--;
        }        
        echo  sprintf('%s岁%s月%s天',$age,$month,$day);
