Year pillar uses 立春 (Start of Spring) boundary. Calculations are in Beijing time (UTC+8). Born outside China? Convert your birth time to Beijing time for accuracy.

⚠️ Timezone & 立春 Note

BaZi is calculated in Beijing time (UTC+8). If you were born outside China, convert your birth time to Beijing time before entering it. The year pillar uses the 立春 (Start of Spring, ~Feb 4) boundary — not Lunar New Year — which is the correct standard for Chinese astrology.

Example: Born at 10 PM on Feb 3 in London (GMT) = 6 AM on Feb 4 in Beijing time. If 立春 is Feb 4, this could shift your year pillar.

Frequently Asked Questions

What is BaZi (八字)?: BaZi literally means 'Eight Characters' — the four pairs of Heavenly Stems and Earthly Branches that encode the year, month, day, and hour of your birth. It is one of the most sophisticated systems in Chinese astrology, dating back over 2,000 years. Your zodiac animal is just one of these eight characters (the year branch).
What is the Day Master (日主)?: The Day Master is the Heavenly Stem of your Day Pillar. It represents your core self — your fundamental nature, strengths, and tendencies. While your zodiac sign (year animal) shows how the world sees you, the Day Master reveals who you truly are at your center.
What is the Five Elements balance (五行)?: Each of the eight characters carries one of five elements: Wood (木), Fire (火), Earth (土), Metal (金), or Water (水). The distribution of these elements across your chart reveals your energetic balance — dominant elements represent strengths, while scarce elements suggest areas for growth.
How accurate is this BaZi calculation?: The calculation uses standard Chinese calendrical algorithms: the 60-year ganzhi cycle for year and day pillars, solar term boundaries for the month pillar, and the traditional Five Tiger/Five Rat methods for stem calculation. The year pillar uses the 立春 (Start of Spring) boundary — the correct standard for BaZi, not Lunar New Year. For birth times near solar term boundaries or the 子时 transition, there may be minor variations depending on the practitioner's convention. International users should convert birth time to Beijing time (UTC+8) for maximum accuracy.

What are the Four Pillars?

Year, Month, Day, and Hour pillars each combine a Heavenly Stem (天干) and Earthly Branch (地支), creating eight characters (八字) that encode your birth energy.

Why It Matters

While your zodiac animal is just the Year Pillar branch, the full BaZi reveals the interplay of all five elements across four dimensions of time.
