写死，纯前端就可以实现，不需要数据库。

我之前写过一段，给你贴个代码，忽略代码里面的flag就行了

四个变量分别是阳历的月和日期、阴历的月和日期

阴历的日期推算，网上有很多的，随便找就OK了

if ((bmon == 1) && (bday == 1)) {

str = "元旦";

flag = "active1";

} else if ((bmon == 3) && (bday == 8)) {

str = "妇女节";

flag = "active1";

} else if ((bmon == 3) && (bday == 12)) {

str = "植树节";

flag = "active1";

} else if ((bmon == 4) && (bday == 5)) {

str = "清明节";

flag = "active1";

} else if ((bmon == 5) && (bday == 1)) {

str = "国际劳动节";

flag = "active1";

} else if ((bmon == 5) && (bday == 4)) {

str = "青年节";

flag = "active1";

} else if ((bmon == 6) && (bday == 1)) {

str = "国际儿童节";

flag = "active1";

} else if ((bmon == 7) && (bday == 1)) {

str = "建党节";

flag = "active1";

} else if ((bmon == 8) && (bday == 1)) {

} else if ((bmon == 10) && (bday == 1)) {

} else if ((bmon == 12) && (bday == 24)) {

} else {

str = $(this).find(".msg2").html();

flag = ""

}
