Nope, never did. And if it's full this kind of "facts", I'd be extra cautious in what I choose to believe from it. Still, it might prove to be an entertaining/amusing read which I'm sure at least contains *some* good guidelines for gardening.You never opened a farmer's almanac then. It's based on thousand of years of observations. Let's see, observations+repeatable results=science.
And various things in the Universe change, ever so little, over time. Things like the various planets, moons, and other objects' exact rotation and revolution times can be affected by various things such as gravitational interaction with a nearby planet or satellite, or even a volcanic eruption or quake on the object itself. Even a close encounter with an occasional massive meteor (or impact of a meteorite) could set things off. Further out, stars move slightly (by our perception here on Earth) over the course of a century as well, and by extension the constellations move as well. Entire galaxies move (generally away from each other) and even collide/merge sometimes. New stars and other objects emerge from the remnants of nebulae.
Even right here on Earth, the various ice ages the planet has gone through in its few billion years of existence have proven just how well this kind of data can be trusted... and that's an extreme example. I don't think you'll get any peppers if you sow seeds on that "special day" when the moon is in its first quarter or whatever in some made-up constellation if you're in an ice age, and I seriously doubt it would be a good way to gauge your activities in 2011. And I'm sure moon phase and constellations had nothing do to with these ice ages on Earth. This is also why I don't believe in the scare of "global warming". The planet's climates have shifted and drastically changed numerous times since its formation with or without us humans interfering and will continue to do so, and looking at steadily increasing temperatures over the last century two or so is a poor way to "prove" anything as it ignores this fact. Some day in the future, we'll be accusing each other of "global cooling" (and eventually freezing). What will be the reason then, over-reliance on electric motors instead of internal combustion engines?
Following something like a certain moon phase or the position of an object in some made-up "constellation" in the sky to plan something like the perfect germination-starting date for peppers sounds insane to me. It's as believable as man turning into a werewolf under a full moon. Or the idea that a groundhog can predict the near-future Spring weather based on what it does when it sees its shadow one day after awakening from its hibernation. It sounds about as factually accurate and based on truths as a certain major religion and related religions from thousands of years ago (not to mention all those unrelated ones). I would look to this kind of "information" for amusement, not for truthful facts to help make the decisions of actual planning of any kind whatsoever.
The Universe is pretty much unpredictable. However, today, there are much better and more accurate ways to predict local events (ie. within the solar system and the Earth itself) than there were way back then--so I see clinging onto a system from thousands of years ago as completely unnecessary. But still, nothing is 100% foolproof. Really, looking as you would through a magnifying glass at the moon in front of a small group of visible stars countless light years into space is quite antiquated for determining local events. I would go so far as to call it nonsense.
