元旦作为新年的第一天，在现代全球广泛采用的公历中被定在每年的1月1日。为什么把元旦定在1月1号，而不是冬至、秋分、夏至之类的日子呢？
Good morning, John!
早上好，观众们！
Happy New Year!
新年快乐！
It's a time for reflecting on the year that has passed, and hoping for a good one to come, but also, as I am incapable of not doing, asking why, WHY, is it this way?
这是回顾过去的一年，希望来年更好的时候，但同时，我不禁要问为什么，
Why January first?
And, if it's gonna be January first, why isn't January first on the solstice?
Well, I'll give you a hint.
This monumental modern institution of our calendar and the way that it works and begins has to do with three people who you have never heard of.
The Earth travels around the sun in a circle, and there is no beginning or end to a circle.
You wanna have a beginning of the year, I get that, and basically we have traditionally just picked one.
And different cultures have picked different dates for different reasons, and they turn out to be really interesting and complicated reasons.
