计算两个日期之间相差的年数月数天数(JS实现)
前言
如何计算年龄？我的第一直觉做法：（当前时间戳 - 出生时的时间戳）/ (365*86400) 所得结果向下取整。后来发现这种做法获得的结果不准确，不是多了一岁就是少了一岁，不能简单粗暴的这么处理，只能把相差的年数月数天数精确的算出来。我一开始以为这个很简单，这个问题不值得记录下来，后来发现不是这么一回事，实现起来没有那么顺利，对我而言。
闰年
要计算2个日期之间的相差的时间，肯定需要知道闰年是咋回事。地球绕太阳公转一圈的时间即为公历一年的时间，地球公转花的时间大概是365天5小时48分，这样每隔4年差不多公历时间多出了一天，这一年天文学家称之为闰年，闰年的2月份是29天。前人总结出来闰年的判断方法：年份能被400整除或者年份不能被100整除且能被4整除。（备注：我对公农历不是很了解，这些信息也是从网上找到的，我对这些不是很感兴趣，没有花更多的时间深入的了解）
实现
先算出相差的年数，再算相差的月数，最后计算相差的天数，思路很简单，真正的实现不是一帆风顺。

后记
1.这个问题的实现花了一些时间思考，一开始不是很想记录下，后来想想毕竟是花了时间思考，现在健忘比较严重，还是记录下吧。
2.跟同事讨论，年龄计算是否需要包含当天生日那天，讨论的结果是不包含，没过生日这天年龄不增加，也算刷新了一个基本常识吧。
3.能算出相差的年数月数天数，如果只需要计算总天数或者总月数就很简单了。
4.农历年份会变化，不能根据农历日期来算年龄
5.PHP农历公历转换类，感谢此类的作者
