今年农历“二月”共有59天！原因是……
你知道吗？
今天是癸卯兔年二月初一
而在这个二月之后
还紧跟着一个闰二月
今年两个农历“二月”
共计有59天！
今年为何会有闰二月？
中国天文学会会员、天津市天文学会理事杨婧介绍，农历是我国传统历法，是一种阴阳合历。阴历是以月亮的盈亏即朔望变化而制定的，一个朔望月的长度是29.53天，而阳历（也称公历）是以地球围绕太阳公转一圈为一回归年而制定的，一个回归年的长度是365.2422天。农历是以阴历为基础兼顾回归年制定的，它的日期既能显示月亮的盈亏变化，又能与公历的四季保持同步。
农历根据月亮的盈亏变化定月，平年12个月，大月30天，小月29天，全年354天或355天。癸卯兔年的农历二月始于公历2月20日止于公历3月21日，为期30天，属大月。
农历平年比回归年要少大约11天。为此，我国古人采用增加闰月的方法使农历年的平均长度和回归年的长度接近，在19个农历年中加入7个闰月，有闰月的那年有13个月，称为闰年，增加的那个月称为闰月，闰年384天或385天。19个农历年和19个公历年的天数几乎相等。
今年闰月
为何安置在二月?
闰月具体安置在哪一个月，这和二十四节气有关，闰月会被安排在农历没有中气的月份。古人将二十四节气分为12个节气和12个中气，二者相间排列。农历以12个中气分别作为十二个月的标志，即每个朔望月都有一个中气，如果某个月中不包含中气，就算做上一月的闰月，为置闰。癸卯兔年的闰二月就是上一个月即二月的闰月，闰二月中只有节气清明，而中气谷雨则在农历的三月初一。这个闰二月从公历3月22日开始至4月19日结束，共计29天，是小月。
闰二月比较罕见，上一次是2004年（甲申年），下一次是2042年（壬戌年）。

过生日按阴历还是阳历？现在才知道原来不能随便过,很多人都错了
过生日，是人生中的一个重要时刻，也是我们与亲朋好友欢聚一堂，共享喜悦的特殊日子。然而，关于过生日的一个问题困扰着许多人：究竟是按阴历还是阳历过生日呢？今天，让我来给您解答这个疑问，让您不再为这个问题犯愁。
首先，我们要明白阴历和阳历的区别。阴历，又称农历、农历，是根据月亮绕地球运行的周期来计算的。每个月的初一，月亮和太阳处于同一方向，这一天称为朔。十五，月亮圆满，称为望。阴历的一个月称为朔望月，大约有 29.53 天。为了弥补阴历年与地球绕太阳运行的时间差，我国采用了闰月的办法，即在每两年或三年的阴历中增加一个闰月，从而使阴历年与阳历年保持一致。
阳历，又称公历，是根据地球绕太阳运行的周期来计算的。阳历的一年有 365 天，分为 12 个月。每个月的天数不是固定的，而是根据地球运行的位置来调整的。为了弥补阳历年与地球实际运行时间的误差，我们采用了闰年的办法，即在每四年的阳历中增加一天，称为闰年。
那么，我们应该按阴历还是阳历过生日呢？其实，这要根据个人的喜好和家庭传统来决定。在我国，许多人习惯按阴历过生日，因为这样更能体现民族特色和传统文化。阴历是我国的传统历法，代表着中华民族悠久的历史和文化底蕴。在阴历生日这一天，我们可以感受到浓浓的乡土气息和亲朋好友的关爱。
然而，随着全球化的推进和国际交流的增多，越来越多的人开始接受阳历，并选择按阳历过生日。阳历具有世界性，可以与国际接轨，方便人们在国际间交流和互动。此外，阳历的生日更容易记住，因为它与我们日常生活和工作中的其他日期相关联。
有些人可能会认为，按阴历过生日会更有纪念意义，因为它记录了我们出生那一刻的地球和月亮的位置。实际上，无论是阴历还是阳历，它们都记录了那一刻的天文现象，只是记录的角度不同而已。因此，我们无需过于纠结纪念意义这个问题。
还有一种观点认为，我们应该在生日这一天感恩母亲，感谢母亲为我们带来的生命和关爱。因此，生日这一天，我们不仅要庆祝自己的成长和进步，还要孝敬父母，传递亲情和爱心。
总之，过生日按阴历还是阳历，并没有绝对的对错之分。关键在于个人的喜好和家庭传统。我们可以根据自己的实际情况，选择合适的方式过生日，既可以弘扬传统文化，又可以拓展国际视野。在这个特殊的日子里，让我们感恩生命，珍惜时光，与亲朋好友共享欢乐和喜悦。
