We’ve pretty much completely discounted astrology as having any meaningful impact on a person’s personality. But what about the seasons of the year, and the weather that comes with them? The stars position in the sky are an indication of the seasons on earth. Right? Wouldn’t a baby that is born into a world of sunshine and warmth have a different early development than one born into the cold and darkness of winter? Has any research been done on the impacts of a baby’s environmental conditions on their personality?
Possibly, though seasons vary wildly across the earth, so results would likely be limited to regions, and even then, we travel around a lot and have things like electricity and indoor heating which would probably negate most impacts.
Plus, the pie is cut up into so many slices that I doubt you could tell the (consistent and significant) difference between the 20th of July and the 1st of August.
On top of that, when it comes to influence on your personality, literally one day (the day you were born) vs. the first 10-16 years in your life… I don’t know man.
