BaZi (Four Pillars) Calculator — Chinese Birth Chart, 10 Gods, Five Elements

Real-world use cases

• Settle a "what year am I really" argument for a late-January baby

  Your friend born 1986-01-28 swears the internet keeps calling him a Tiger, but his parents say Ox. Enter the date and pick the hour: BaZi uses the 立春 cutoff (~Feb 4), so a Jan 28 birth still sits in the 乙丑 (Ox) year, not 丙寅 (Tiger). The year pillar on screen ends the debate, and the FAQ link explains why folk CNY reckons it differently.

• Check whether your chart is missing an element before a name choice

  Parents picking a baby name often want to know which of the five elements is absent. Enter the child's birth date and hour, read the balance bars: if Metal shows 0 across all 8 characters while Wood shows 4, you can see the chart leans heavily Wood with no Metal at all. That tells a name consultant where to focus, far faster than counting strokes by hand.

• Map your Major Luck decades before a big career move

  You are 33 and weighing a job switch. Enter your full birth data and read the 大运 row: each pillar covers 10 years with its starting age marked, e.g. luck pillar 戊午 running ages 32 to 41. You see which decade you just stepped into and which stem-branch colors the next one, useful as a cultural lens on timing rather than a forecast.

• Verify a paid reading you already received

  A street fortune-teller charged you for an "eight characters" reading and you want to sanity-check the raw chart. Re-enter the same date and double-hour here: the four pillars, Day Master, and Ten Gods are computed by orthodox 子平 rules, so you can confirm they wrote down 甲子 day not 甲午, and that the 七杀 they mentioned actually appears in your chart.

Common pitfalls

• Entering folk lunar New Year as the year cutoff. BaZi uses 立春 (~Feb 4); a 2024-02-03 birth is still 癸卯, not 甲辰, even though CNY 2024 fell on Feb 10.

• Forgetting the double-hour and leaving it at default. A 23:30 birth falls in the 子 hour and shifts the hour pillar (and sometimes the day pillar) versus a 22:00 birth, changing the eighth character.

• Reading "all five elements present" as a balanced chart. A 甲 Day Master rooted in 寅 is far stronger than the raw count shows, so check the season and rooting before calling it balanced.
