FAQ
A 10-year luck cycle, or Da Yun, is a decade-level timing pillar used to read the changing environment around a BaZi chart.
Traditional Da Yun direction depends on gender and the yin-yang quality of the birth-year stem, so the same birth date can produce a different sequence.
No. The free calculator shows the table, current cycle, and a short element summary. Paid reports interpret the whole chart and timing interaction in depth.
For BaZi, true solar time can matter when birth time is close to a two-hour boundary. Use longitude values when accuracy is important.
The public page gives users a useful free result and keeps the deeper report as an intentional upgrade path.
