据说24节气使用两千多年，却没有用365天记年，什么水平？

[╭∩╮（￣▽￣）╭∩╮]

365天记年完全放弃了天空中第二明显的天象，月亮。

I think this is an intuitive outstanding answer, it actually gives out at least one angle of the reasonable view

农历是阴阳历 显然比纯阴历和纯阳历高级几条街

[╭∩╮（￣▽￣）╭∩╮]

中国 古代的24节气 是锚定在农历基础上的，很不准的。

后来 明朝传教士 汤若望等 带来 365天的公历概念，才把24节气 改成 锚定在 公历上的

if that's the case, then putting "据说" in the title was a right decision

[╭∩╮（￣▽￣）╭∩╮]

地球这个小球围着太阳转一圈算一年， 在汤若望之前，中国古人是没有这个概念的

I think it's a valuable point, 年 was a beast, to clearly picturizing 年 is rotating a whole circle DOES have conceptual level improvement, huge.

Well without knowing that, the sense of recirculation is still there. Seasons come back again and again, yet the beast returns every 365 days didn't become a formal concept...

ALSO, before 汤若望, before sun-center model, the 365-day calendar has been officially used for long time, right?

诺曼底登陆的历史书有个细节，计划的前几个月用了无数最高级密电跟美国国内的天文学家确认，6月份满月是哪一天。要是蒋介石指挥就不用这么麻烦了。

难以相信啊，满月与潮汐计算在英国这样的航海大国里面算是k-12的知识点吧

可能不是巴顿的知识点？

农民耕种都是按24节气的。按新历几月几号不行。

就跟四川火锅店吹嘘自己两千年火锅历史一样，都是瞎胡吹。24节气是阳历的。
