There's a wee problem with the hyperlink here. However, if you check the
Address Bar and remove anything after the 'com', you should get there.

To check for when that increased wooliness and tooth elongation is scheduled
to happen so we can safely shut ourselves in a cage for the duration of the
full moon and not eat our friends.  ;)

After furious head scratching, Vadim asked:

In magic, different spells are done at different phases of the moon (or sun).
For example, if you wanted to INCREASE your wealth, you'd do your first spell
just after the New Moon and finish at the Full Moon. But if you wanted to
DECREASE or REMOVE the warts on your hand, you'd start just after the Full
Moon and finish at the New Moon. Maybe the same applies in business and other
fields of human endeavour!

It's not as unreasonable an idea as it might seem. Maybe human beings *are*
affected by the light and other energies pouring from the moon. In the days
when humans were hunter-gatherers, moonlight could sometimes be relevant,
even though humans are mainly daylight-oriented. Many women, and even some
men, say that moon phases affect their mood.

Of course, if you were in the military, New Moon would be the best time for
a night attack because the light would be minimum and the enemy would be less
likely to see you coming.

I hope that helps.
