BaZi Four Pillars Calculator

Supports Solar / Lunar conversion: enter either date → auto-convert to the other calendar → compute BaZi using Solar date + solar terms. Boundary hours for solar terms may differ slightly across software.

Input Local

Example: enter a lunar date to see the corresponding solar date; enter a solar date to see the corresponding lunar date (including leap months when applicable).
Notes:
1) The Year Pillar switches at Li Chun; the Month Pillar switches by the 12 “Jie” solar terms (starting from Yin month at Li Chun).
2) Lunar input is converted to a solar date first, then used for solar-term boundary checks and four-pillar calculation.
3) Day boundary is fixed at: 23:00 as the day-switch point (Zi hour start).

Tip: If your result differs from another BaZi app, common reasons include:
  • Different “day boundary” (23:00 vs 00:00)
  • Year boundary: Li Chun vs Lunar New Year
  • Different solar-term calculation precision (especially the boundary hour on the term day)
