js的农历算法_农历的算法是怎么算的

㈠ JS获取农历日期的原理是什么，有人能解释下吗

有国际化、皮肤和一些配置的文件，这些文件会互相调用，不能单独工作，你页面上的写法是正确的，我想应该是js类库缺少文件或者是文件的相对位置被改变了。

㈡有谁知道js的农历算法是怎么写出来的

其实我也不懂这个算法，网上粘贴的，我觉得可以不去深究这个公式，反正有现成代码：

设：公元年数－1977（或1901）＝4Q＋R
则：阴历日期=14Q+10.6(R+1)+年内日期序数-29.5n
（注:式中Q、R、n均为自然数，R<4）
例：1994年5月7日的阴历日期为：
1994－1977＝17＝4×4＋1
故：Q＝4，R＝1 则：5月7日的阴历日期为：
14×4+10.6(1+1)+(31+28+31+30+7)-29.5n
=204.2- 29.5n
然后用29.5去除204.2得商数6......27.2，6即是n值，余数27即是阴历二十七日。

㈣求js详细时间代码，年月日星期时分（秒），阴历日期

㈤用js实现离当前时间最近的节日的涵数，如果能用给追加分数。

js代码扩展：

调用代码示例：

window.onload=function(){

结果输出：

2014-04-01 农历甲午年三月初二

㈦农历的算法是怎么算的

农历一年为12或13个月，每个月天数依照月亮围绕地球运行周期而定，为29或30天，闰年为13个月，中国农历年平年为353或354天，闰年为384或385天，平均每年约为365.2422天（即地球环绕太阳一周的时间）。

农历基本上以19年为一周期，由于农历一年约为355日，与地球年相差约11日左右，所以每3年要置一闰月，每19年要置7个闰月。有闰月的年份也叫闰年，具体闰哪个月，则要视节气情况灵活而定。如公历的2001年5月27日、1982年5月27日和1963年5月27日这个日子，都是闰四月初五。

闰月加到哪个月，以农历历法规则推断，主要依照与农历的二十四节气相符合来确定。自冬至开始，逢单数为节气，逢双数为中气，如轮到一个月只有节气没有中气，即为上一个月的闰月。农历的闰月天数与正常月份天数一样，为29或30天。

(7)js的农历算法扩展阅读：

农历的优点：

1.农历是定历，它具有天文年历的特性，能很好地和各种天象对应，如它的节气严格对应太阳高度，历日较严格地对应月相，闰月的不发生频率和发生频率对应地球近日点和远日点，其它天象如日出日没，晨昏蒙影，五星方位，日月食，潮汐等，就连历月也大致对应太阳高度；

2.农历历月的天数只有29日和30日两种，且由定朔日规定，人为因素最小，不易随意改动；

3.岁首有较强的天文学意义，具有阴月阳年的天文学意义；

4.阴阳合历，最体现汉民族天人合一、阴阳和谐的传统文化；

5.干支纪年和十二生肖纪年循环使用；由于它包含节气十分利于四季划分，由于它包含月相，所以也十分反映潮汐，日月食等天象和月亮对气候的影响。
