Does the full moon affect mood and behavior?
What's actually true — the astronomy
A "full" moon is simply the Moon at ~180° from the Sun in ecliptic longitude — exact and predictable to the minute. AstralMath computes lunar phase directly from the ephemeris.
What the tradition says (interpretation)
Astrology treats the full moon as a peak of emotional intensity and culmination — a symbolic reading, not a physiological claim.
The decision-science move — what to actually do
If tracking the moon helps you reflect on a monthly rhythm, that is a fine personal ritual. But do not attribute a decision, a mood, or an outcome to it — the evidence does not support a causal effect.
