Astrological ages last an average of 2,000 years (mathematically is 2,160 years, but precession and other factors alter the calculations). Your mate is wrong, we have been in the Age of Pisces since Jesus was born and will enter the Age of Aquarius anytime now. Some say it began in May 2000 with the conjunction of planets. We enter the Age of Capricorn around 4000 AD.
Now astrology is mostly stupid, but consider that the concept of astrological age is actually rooted in ancient science (astrology is just the ancient version of astronomy) and is thus related to shit like how ancient Christians calculated the date of Easter year after year. The 2K year thing is probably coincidential. Interestingly, it's fairly close to the Mayan Long Count, where shifts in the calendar were marked by great wars although that was straight up political since if some dude staged a coup in his city based on the calendar he'd automatically legitimize his rule.
If it's tribalism, you really do need to know your neighbors. It's how it works in Africa, at least according to a few guys from Africa (professors and students) I knew in college. They don't want weirdos messing with you, because it means they might be next. Bubba down the road with the big ass dog he barely controls and barks all night might actually be your good friend in this time.
Well there's like one black dude in my neighborhood, he seems okay. I hope no one beats him up in these challenging times
