以前看同學在單片機上搞萬年曆，我覺得蠻實用的，想看看。公曆好說，簡直不要太簡單，判斷閏年的一句 if(year%4==0 && (year%100!=0) || year%400==0)就over了。但農曆就非常麻煩。農曆的二十四節氣能知道農業生產，而且是根據月亮的晦朔來的，完全沒規律可言，或者說在那幾天波動，閏月也沒公曆方便。百度了很久也沒發現道理。最後看別人的例子，農曆的信息全都在一個數組裏，一般都可用到2100年，全都是天文臺觀測好了的。到用了差不多的時候，會繼續觀測。
這裏給一個可以用的html代碼和有註釋的js.網上搜到的時候都是經過壓縮的，從別的網站搞來個優化美化css、js和html的工具，很好用。
