Enter the date, time and place you were born and this calculates your Four Pillars of Destiny, the eight characters of a BaZi chart: a heavenly stem over an earthly branch for the year, month, day and hour.
You get your day master, the balance of the five elements, the hidden stems inside each branch, your ten-year luck pillars, and the structure your chart falls into. The reading is written in plain language rather than jargon.
The month pillar turns on the solar term, not the calendar month, and the solar longitude here is computed with VSOP87D rather than read from a table. If your birth falls within a day of a boundary the reading says so and shows you both readings instead of quietly picking one.
No account is needed and the chart is free.
