Esoterics: Why Is It That My Good Luck And My Bad Luck Tend To Fall In Specific Months?

I have noticed many patterns in my life, lives of others, the nation, etc. I have also noticed that my good luck and my bad luck tend to fall into certain time periods during each year, and also that during certain years (every so many, say 5, 7, or 11) I tend to have extraordinary luck (be it good or bad).

Specifically, I would like to know why it is that about every May/June, August/September, November/Decmeber, and February/March I tend to fall upon bad luck (more often than all other times), but sometimes it is good rather than bad. I especially notice it taking place in September, but I always chocked this up to it being the end of the business year and how finances effect us throughout every area of our lives.

Also, I've noticed year-to-year cycles such as when I was 8, 16, and 24 (not so much 32) when I had dramatic changes in my life.

Any explanations for this? I see the cyles and the patterns, but how am I to pinpoint them?

I've also noticed that these cycles of "luck" tend to effect the outcome and success of the use of certain unconventional energies.
