工作中要写一个活动月历（包含公历和农历），在网上找了相关的解决方案，最后整理如下：
一、表格行数问题
既然要显示日期表格的话，首先得知道这个表格有多少行多少列，列数是已经确定的，从星期天（日历上第1列是星期天）到星期六一共7列。要解决行数问题之前，还得先知道这个月的第1天是星期几，因为每个月的1号并不都是从日历上的星期天开始排的，可能1号是星期五，星期六也说不定，所以1号的左边部分，就得用空表格代替了。那么用多少个空表格代替呢，这里就得用到getDay()方法了，该方法返回数组[0-6]中的一个数字，0代表星期天，1代表星期一，2代表星期二，以此类推。所以如果一个月的1号是星期五的话，那么刚好左边需要5个空表格代替。然后，假如一个月有31天，最后求出的表格行数就是：var tr_nums = Math.ceil((5 + 31)/7);
当然，并不是每个月都是31天，所以我们得创建一个包含12个月份的数组，每个元素代表每个月份所包含的天数。但是2月份比较特殊，闰年的2月份有29天，平年的2月份只有28天。所以，在创建数组之前，得自己创建一个判断闰年的函数：
//如果当前年份能被4整除但是不能被100整除或者能被400整除，即可确定为闰年，返回1，否则返回0function isLeap(year) { return year % 4 == 0 ? (year % 100 != 0 ? 1 : (year % 400 == 0 ? 1 : 0)) : 0;} 然后我们创建一个月份数组：
var days_per_month = new Array(31, 28 + isLeap(year), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
这样就能保证无论是平年还是闰年都会取出正确的天数，下面的代码用于获取今天的相关信息：
var today = new Date(), //获取当前日期 y = today.getFullYear(), //获取日期中的年份 m = today.getMonth(), //获取日期中的月份(需要注意的是：月份是从0开始计算，获取的值比正常月份的值少1) d = today.getDate(), //获取日期中的日(方便在建立日期表格时高亮显示当天) firstday = new Date(y, m, 1), //获取当月的第一天 dayOfWeek = firstday.getDay(), //判断第一天是星期几(返回[0-6]中的一个，0代表星期天，1代表星期一，以此类推) days_per_month = new Array(31, 28 + isLeap(y), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31), //创建月份数
所以最后就可以获取当月所需表格的行数：
var str_nums = Math.ceil((dayOfWeek + days_per_month[m]) / 7); //确定日期表格所需的行数
二、阴历的问题
从小就没搞懂了阴历和阳历中的换算问题，幸运的是从其他牛人那里找到了阴阳历的转换js代码：ConvertCalendar.js/** * @1900-2100区间内的公历、农历互转 * @charset UTF-8 * @Version 1.0.2 * @公历转农历：calendar.solar2lunar(1987,11,01); //[you can ignore params of
