What if I do not know my birth time?
Learn what remains reliable in a Saju chart when the Hour Pillar is unknown and how Qiora handles its noon placeholder.
Short answer: You can still read the Year, Month, and Day Pillars when the birth time is unknown. The Hour Pillar remains unverified.
In Qiora, the Hour card should display a question mark. Some downstream calculations need a technical value, so the system may use noon internally. That noon value is a placeholder, not a recovered birth time and not evidence that the person has an O Hour.
What you can read
The first three pillars still provide six visible characters, the Day Master, Month Branch and season, many Hidden Stems, Ten God relationships, and natal interactions that do not depend on the Hour.
State the limitation. A six-character reading can be substantial, but it is not the same as a verified eight-character chart.
What to leave open
Do not count the placeholder Hour’s element, interpret its animal, use its Special Stars, or make claims about the Hour Pillar’s traditional themes. Timing techniques that depend on the Hour should also remain conditional.
If a family record narrows the time to a range, compare only the possible Hour Branches and look for dated evidence. Do not choose the chart that sounds most flattering and call the process rectification.
Birth-time rectification is an advanced and disputed practice. It should show its assumptions, use events recorded before the conclusion, and preserve uncertainty.
