把中国传统历法与古代天文星象，整理成可查、可算、可核的东西。
立春那天出生的孩子，生肖该按哪个算；古人没有钟表，怎么知道现在是几点；黄道和白道，到底差在哪儿——这些是日常里被反复问到的问题，看着零碎，底下是同一套历法与星象的构造。于是按顺序一篇篇写下来。
凡涉及具体时刻、日期、星位的地方，都以可查的历算数据与传世文献为据；能给出来源的给出来源；文献之间有分歧的，把分歧本身写出来，不替读者选边。不含预测性论断，亦不涉个体测算。
What I am doing is to put the traditional Chinese calendar, and the astronomy behind it, into a form that can be looked up, computed and checked.
Which zodiac year does a child born on the first day of spring actually belong to? Without clocks, how did people know what time it was? Where exactly do the ecliptic and the lunar path part ways? These are asked all the time; they look scattered, yet the same calendar and the same star system sit underneath. So the pieces are written out one by one, in order.
Every figure for a moment, a date or a position is tied to ephemeris data that can be re-computed and to sources that can be looked up. Where sources disagree, the disagreement itself is set out rather than settled on the reader's behalf. No predictive claims, and no individual readings.

| 历法公共数据集 Calendar & Chronology Datasets |
二十四节气交节时刻（公元 1900—2052，逐年逐节气，精确到秒）／历代历法改革年表（52 部）／干支纪日对照表（逐日）。每件数据旁附核验表，另附考异表。 Solar-term instants (CE 1900–2052, year by year, accurate to the second) · a chronology of 52 calendar reforms · a day-by-day sexagenary (ganzhi) day table. Each dataset ships with a verification table, plus a separate table of textual discrepancies. |

| 历法与古天文学术语对照表 Chinese–English Terminology Glossary |
279 条术语，分 19 组，逐条给中文名、英文定译、中文释义与英文释义，并标出与「术语在线」（全国科学技术名词审定委员会）的对应（同名 147／近名 21／未收 111）。中文页与英文页逐条对拍 279/279 一致；另附二十八宿距星三源对照表与星官星数表。 279 terms in 19 groups, each with a Chinese name, a fixed English rendering and one-line definitions in both languages, together with its correspondence to Termonline, the terminology platform of China's National Committee for Terms in Sciences and Technologies (147 identical / 21 near / 111 not listed). The Chinese and English pages were checked item by item — 279/279 agree. Two 28-row tables on the twenty-eight lunar mansions are appended. |

-
节气怎么定：太阳走到黄经多少度算交节，为什么每年差一两天。
-
干支怎么换岁：立春换、还是正月初一换，两说的来路在哪。
-
方位与时令怎么对上：什么时节做什么事，老话说得有没有理。
-
古代天文与星空：黄道、白道、赤道三条道；三垣与二十八宿；磁针出现之前，古人怎么定方向。
-
How a solar term is fixed: at which solar longitude the term begins, and why the date drifts by a day or two from year to year.
-
How the ganzhi year is renewed: at the first day of spring, or at the first day of the first month — and where each reading comes from.
-
How direction and season are matched: what is done in which season, and whether the old sayings hold up.
-
Historical astronomy and the sky: the ecliptic, the lunar path and the equator; the three enclosures and the twenty-eight mansions; how direction was found before the magnetic needle.
