立春 · Start of Spring
The solar term called Start of Spring (立春): its exact moment for ten years, in Beijing time, and what it means for a BaZi chart.
What these words mean
- BaZi (八字): Chinese "four pillars" astrology. The moment you were born is written as four pillars, for the year, the month, the day and the hour.
- Pillar: a pair of symbols: a stem written on top and a branch below it. Your year pillar is the pair for your year of birth, and your day pillar the pair for your day of birth. Four pillars make eight symbols, which is what BaZi means: "eight characters".
- Solar terms (节气): 24 fixed points in the sun's yearly path, about 15 days apart. A BaZi month starts at a month-opening term (节), and the year starts at the Start of Spring (立春), around February 4.
立春
节：八字在此换月柱 · 同时是八字换年的分界
A month-opening term: the BaZi month pillar changes here.
立春是八字一年的开始。在立春交节之前出生的人，年柱仍属上一年：这一点与农历新年无关，也与元旦无关，是这个行业里最常被算错的一条。
The Start of Spring is where the BaZi year begins. Anyone born before its exact moment still has the previous year's year pillar. This has nothing to do with Chinese New Year or January 1, and it is the rule this field gets wrong most often.
交节以分钟计：同一天里，交节之前出生仍是上一个月柱，之后才换。下表列出每年的交节时刻，以及这一刻前后的年柱与月柱。
The term is counted to the minute. On the day itself, a birth before the exact moment still takes the previous month pillar, and a birth after it takes the new one. The table gives the moment for each year, and the year and month pillars on either side of it.

时刻为北京时间（UTC+8），按天文算法解算到分钟，与香港天文台公布的近年时刻最多差一分钟。在中国以外出生的，先换算成北京时间再对照。Times are Beijing time (UTC+8), calculated astronomically to the minute, and within a minute of the Hong Kong Observatory's published times. If you were born outside China, convert your birth time to Beijing time before you compare.
