Sunny....
So you won't be so helpless next time
1. Find Sun's position for date in question.
2. Find Moon's position for date in question.
3. Moon moves Counterclockwise through zodiac (oh oh....Sunny is probably so young he's never seen an analog clock in motion.....oh well)
4. Take the point opposite the Sun's position (say Sun is 3 Gemini, the point opposite is 3 Sagittarius). If the Moon is past that point (by counterclockwise motion from the place of the Sun,) it is waning. If before, waxing.
In other words if before full moon, the moon is "increasing in light" and waxing (growing)
If after full moon it is "decreasing in light" and waning (dying).
The symbolism fits the idea of "growth" and "decline"......externalizing, internalizing......fattening, emaciating.....and so on.
"On the upswing", "on the downswing"
"Going out", "coming in"
"building," "destroying"
"sowing", "reaping"
"rising", "falling"
We live in a world of Duality (Yin, Yang and so on). The Moon is the primary symbol of this duality....It is the "ruler" of our world, what the ancients refer to as "the sub-lunar world." It has to do with the immediate cycles of everyday existence.
Tip for the hefty gals in the audience who want to lose a few pounds: Begin your diet (fast) on the wane of the Moon.
And for the Wannabe Tycoons: If you're buying a speculative stock with hopes of a rise in price, buy on the waxing Moon.
That's the idea, in theory.
