玛雅人为何能编出如此精确的历法,他们主要观测了什么?

How did the Maya make such precise calendars, and what did they observe?

玛雅人长期记录金星出没周期(约584天)、日月食和岁差,用观测台对齐天体升落,其长纪历精度可与现代比拟。
The Maya tracked Venus's 584-day cycle, eclipses and precession with precise observatories aligned to risings and settings, achieving Long Count accuracy rivaling modern reckoning.

为什么公历规定'四年一闰,百年不闰,四百年再闰'?

Why does the Gregorian rule say 'leap every 4 years, skip centuries, keep multiples of 400'?

回归年约365.2422天,四年一闰会略多,所以整百年不闰、但能被400整除的仍闰,使平均年长精确到365.2425天,误差数千年才差一天。
The tropical year is ~365.2422 days; leaping every 4 overcounts, so century years skip unless divisible by 400, giving an average of 365.2425 days—off by a day only over thousands of years.

干支纪日和生肖纪年,哪一个和天文观测关系更直接?

Between the ganzhi day count and the animal zodiac, which is more directly astronomical?

干支纪日连续60天循环,是对时间本身的均匀切分;生肖依附于年,而年的长度由太阳回归决定,二者都源于对天体周期的测量。
The ganzhi day count is a uniform 60-day cycle of time itself; the zodiac depends on the year, whose length is set by the solar return—both stem from measuring celestial periods.

为什么很多文化的新年不在同一天?

Why don't different cultures celebrate New Year on the same day?

各地历法依据不同:公历以1月1日、农历以立春附近的正月初一、伊斯兰历随月相游移、伊朗以春分——新年日期反映了各自的历法逻辑。
Calendars differ: Gregorian Jan 1, Chinese New Year near spring's start, Islamic by the moon, Iranian at the equinox—each New Year reflects its own calendar logic.

#新年 #历法对比

为什么二十四节气在公历上日期基本固定,春节却每年变动很大?

Why are solar terms nearly fixed on the Gregorian calendar, yet the Chinese New Year date varies a lot?

节气按太阳在黄道的位置(阳历性质)而定,所以公历日期稳定;春节按朔望月(阴历)定,农历置闰使它在1月21日至2月20日间游移。
Solar terms follow the Sun's position (solar-based), so they're stable on the Gregorian calendar; the New Year follows lunar months, drifting between Jan 21 and Feb 20 due to intercalation.

公历规定能被4整除的年份置闰,却又排除能被100整除但不能被400整除的世纪年,这样复杂的规则从何而来?

The Gregorian calendar adds a leap day to years divisible by four but skips century years not divisible by 400—what motivates such an intricate rule?

回归年长约365.24219天。儒略历四年一闰,年平均365.25天,每年比回归年多约11分钟,约128年便多出一整天。格里高利历去掉三个世纪闰年后,年平均为365.2425天,与回归年每年仅差约26秒,约3300年才累积一天,使春分日期长期稳定在3月21日附近。
The tropical year lasts about 365.24219 days. With a leap day every fourth year, the Julian calendar averages 365.25 days—about 11 minutes too long each year, gaining a whole day roughly every 128 years. Dropping three century leap years per 400 years brings the average down to 365.2425 days, within about 26 seconds of the tropical year, limiting the drift to one day in roughly 3,300 years and keeping the spring equinox near March 21.

为什么伊斯兰历的节日每年都会提前约11天?

Why do Islamic holidays move about 11 days earlier each year?

伊斯兰历是纯阴历,一年12个朔望月约354天,比太阳年短约11天,所以节日相对季节不断前移,不与寒暑绑定。
The Islamic calendar is purely lunar—12 months of about 354 days, ~11 short of a solar year—so its holidays drift earlier each year, untied to the seasons.

公历和农历有什么区别?

What is the difference between the Gregorian and lunar calendars?

公历以地球绕日周期(太阳年)为准;农历兼顾月相和太阳年,用闰月来对齐季节,所以节日公历日期会变动。
The Gregorian calendar follows the solar year; the lunar calendar tracks both moon phases and the solar year with leap months, so festival dates shift on the Gregorian calendar.

一星期为什么是7天?

Why is a week 7 days?

七天一周源自古代近东,把肉眼可见的7个天体(日、月、金、木、水、火、土)各对应一天,后来随历法传播到全世界。
The 7-day week came from the ancient Near East, naming each day for one of the seven visible 'planets' (Sun, Moon, and five wanderers), spreading worldwide with calendars.

生肖为什么是12个,和星星有关系吗?

Why are there 12 zodiac animals, and is that linked to the stars?

12生肖对应12地支,而12地支源于木星约12年绕天一周的观测;西方黄道也有12宫,是不同文明对'12'这一周期的有趣巧合。
The 12 animals match the 12 earthly branches, derived from Jupiter's ~12-year orbit; the West's 12 zodiac signs are a curious parallel to the same number.

为什么公历有的年份是366天?

Why do some Gregorian years have 366 days?

地球绕太阳一周约365.24天,每4年多出约1天,所以每隔几年在2月加一天(2月29日)成为闰年,让日历和季节同步。
Earth takes about 365.24 days to orbit the Sun, so roughly every 4 years we add a leap day (Feb 29) to keep the calendar in step with the seasons.

农历的'闰月'是怎么来的?

How does the lunar calendar get its 'leap month'?

12个朔望月约354天,比回归年短11天;为使农历月份与季节对应,约每19年加7个闰月,让平均年份贴近太阳年。
Twelve lunar months total about 354 days, 11 short of a solar year; to keep months aligned with seasons, about 7 leap months are added every 19 years.
