Li Chun (Beginning of Spring)
Li Chun is the true BaZi year boundary. Unlike Chinese New Year, which shifts, Li Chun is a fixed solar term that usually arrives around February 4 each year.
What Is Li Chun?
Li Chun (立春) translates to “Beginning of Spring.” It is the first of the 24 Solar Terms and falls when the sun reaches 315° longitude, typically on February 4.
For thousands of years, Li Chun has been treated as the symbolic start of the year in both farming and astrology. While Chinese New Year celebrates family and culture, Li Chun is the technical anchor for calculations like BaZi charts.
Why Li Chun Matters in BaZi
- Year Pillar Definition: BaZi assigns the year stem-branch at Li Chun, not at Chinese New Year.
- Consistency: A solar term is astronomically precise, while lunar months drift without correction.
- Avoiding Errors: Without Li Chun, birthdays in late January or early February would be misclassified.
Example: A baby born on February 1, 2024 — before Li Chun — belongs to the 2023 Gui Mao year in BaZi terms, even though Chinese New Year has already passed.
