In one line: chart it right, then say it warm. This page opens up every step of the "charting it right".
You give us clock time, but metaphysics needs the sun's position. We first resolve your birthplace to precise coordinates, then look up the real time zone in force at that place, in that year — including long-abolished daylight-saving regimes. Many people don't know they were born during DST; one hour off can change the whole chart.
Then comes true solar time correction: using your longitude and the astronomical equation of time, we convert clock time to the sun's actual position. A few minutes can cross an hour-branch boundary.
Your BaZi is computed by one professional calendrical engine; your Zi Wei chart by a second, fully independent one — two systems, each calculating from scratch.
We then cross-check the results: do the four pillars match, the lunar date, the hour branch? Only a perfect match earns the "verified" stamp. A mismatch triggers manual review.
Born minutes from an hour-branch boundary? Standard time and true solar time in different branches? A DST switch on your birthday? We never gloss over these — your confirmation page flags them clearly, so you know and you decide.
Every calendrical calculation can be verified against observatory almanacs. We don't ask for faith — we give you something you can check.
Most AI fortune products let the AI "guess" your chart — we've tested this, and it fails badly. At Destiny Handbook, the AI never touches the calculation.
Only the computed, verified chart is handed to the AI for what it's genuinely good at: turning traditional conclusions into warm, specific writing that belongs to you alone. Every analysis cites its metaphysical basis — dig as deep as you like.
"The chart must be right first." — That is the foundation of the entire book.
Your birth clock-time is converted to true solar time using your birthplace's longitude and the astronomical equation of time — a few minutes' difference can change your entire hour pillar.
We automatically check the real time zone and daylight-saving rules for the exact year and place you were born — even decades-old regimes long since changed.
BaZi and Zi Wei are computed by two independent professional charting engines, then cross-verified — we only proceed once they agree.
Every calendrical calculation can be checked against observatory almanacs. Your confirmation page lists the full basis for your chart, fully transparent.
