No, leaving the birth time blank produces an honest three-pillar chart. Adding your birth time generates the complete Four Pillars including luck pillars.

How does birth city affect the calculation?

Entering your birth city corrects the clock reading to true solar time for that longitude and removes daylight saving time adjustments if applicable that day.

Is any personal data stored when I use the calculator?

No, the site states that nothing you enter is stored.

Can I see examples of how the chart interpretation works?

Yes, the tool provides four public life charts as illustrations, showing how the engine maps ten-year luck cycles and peak decades for known figures.
