Before you calculate
Can I use it without a birth time?+
Yes, as a provisional chart. The hour is omitted and the remaining calculation uses local noon. Near solar terms or corrected date boundaries, other pillars can also be uncertain.
Does this predict my future?+
No. Calendar calculations are reproducible, but the readings are cultural reflection prompts rather than scientifically validated forecasts.
What is included for free?+
Four Pillars, Day Master, visible element counts, hidden stems, Ten Gods labels, reading prompts and a downloadable chart. No payment or account is needed.
