The Farmer's Almanac has nothing to do with astrology.
Looking to various seasonal patterns to get an idea of what to expect in the year ahead is helpful for those who rely on that kind of information for their livlihood. And it's not divination or magic, it's just science.
When I see dark clouds rolling in, I have a pretty good feeling that it's probably going to rain. That isn't divination, that's just recognizing a common pattern in the natural world.
Astrology is very different. Astrology looks to the stars to try and read the fates and destiny of men, and that's pure bunk. The particular arrangement of what the night sky looks like when we were born has absolutely no influence on the course of our lives, there is no such thing as fate. I'm not going to have a good day or a bad day because the moon is located near some arbitrary collection of stars from my earth-bound perspective here on earth.
That's why astrology is wrong, because it's just nonsense.
It's what the Church has historically called δεισιδαιμονία (deisdaimonia), which in the neutral sense just means "religion" or "reverence for the spiritual", but came to be used in a Christian context to specifically refer to false spirituality, and hence its translation into Latin as superstitio, from which we get "superstition". An "excessive dread" of spiritual or religious things, such as belief in witches, astrology, divination; or in modern times, believing crystals have power, or being terrified that the devil might be hiding in works of popular fiction, or--and this is relevant here--a fear of angering God because you're reading the Farmer's Almanac.
