CNN News: 闰年

Ten-second trivia:

十秒快速问答。
 
Which of these historic calendars was created the most recently?
以下哪个日历是最新创立的？
 
Julian calendar, Byzantine calendar, Hebrew calendar, or Gregorian calendar?
略历、拜占庭历、希伯来历还是公历?
 
The Gregorian calendar, which is widely used today was proclaimed in 1582.
 
今天广泛使用的公历是在1582年宣布的。
 
AZUZ: And it includes a date that only comes along every four years, leap day, February 29th. This year that happens to be this Saturday. February ends on the 28th in non-leap years.
 
它还包括一个每四年才出现一次的日期:2月29日的闰日。今年正好是这个星期六。二月若以2月28日结束，则为非闰年。
 
So why do we have the extra day? It's the earth's fault. On the Gregorian calendar at least, it doesn't complete its orbit in exactly a year.
 
那么为什么我们会有额外的一天呢?这是地球的错。至少在公历上，它的公转周期不是正好在一年。
 
GEOFF CHESTER, U.S. NAVAL OBSERVATORY: It goes around the sun once in 365 and almost a quarter day, almost but not quite. So, in order to rectify this, we have to periodically add an extra day to the calendar.
 
它每365天绕太阳一周，几乎是1 / 4天，但也完全不是。所以，为了纠正这一点，我们必须定期地在日历上增加额外的一天。
 
AZUZ: That happens every four years, hence the leap day, and it coincides with presidential election years in the United States.
 
每四年发生一次，因此有“闰日”，而美国的总统选举年正好是这一天。
 
Besides that though, does it matter that 2020 will have 366 days? Well, those who were born in the leap year on February 29th will actually get to celebrate their birthdays on the 29th instead of on February 28th or March 1st.
 
除此之外，2020年有366天有关系吗?嗯，那些出生在闰年2月29日的人实际上会在29日庆祝他们的生日，而不是在2月28日或3月1日。
 
And there is some interesting history associated with leap years. According to Irish tradition, years with 366 days were years when women could propose to men when it was the other way around in non leap years. Beyond that though, well, you only get to say happy February 29th every four years, so go crazy with that y'all.
 
还有一些关于闰年的有趣的历史。根据爱尔兰的传统，有366天的年份是女性可以向男性求婚，而在非闰年则正好相反。除此之外，你每四年只能说一次“2月29日快乐”，所以大家都要疯狂地说出来。
