Q: What is the best time of day to make an important decision?

Astrology divides day and night into planet-ruled "planetary hours" and would pick, say, a Jupiter hour for a big commitment. That scheme is computable from real sunrise and sunset, but it has no proven effect on outcomes. What is proven: most people reason best in the late morning and make worse choices when tired or hungry. Decide important things when you are rested and fed — and if a planetary hour helps you commit, use it as the nudge.

What's actually true — the astronomy

Planetary hours are exact: they divide the real interval from sunrise to sunset (and sunset to sunrise) into twelve, each ruled by a planet in a fixed order. AstralMath can compute them from your location. The division is real; the influence is interpretation.

What the tradition says (interpretation)

Electional astrology favors the hour of a benefic (Jupiter, Venus) or the ruler of the matter at hand for starting something important.

The decision-science move — what to actually do

Anchor on the evidence first: avoid decision fatigue, low blood sugar, and late nights. Then, if you like ritual, align with a favorable planetary hour — it costs nothing and can sharpen intent. The timing that actually moves the needle is your physiological state, not the hour's ruler.
