Celestial Origins of Halloween
Halloween traces its roots back to the ancient Celtic festival of Samhain, marking a significant cross-quarter day between the autumnal equinox and the winter solstice. This festival was deeply intertwined with celestial events and the seasonal changes that governed agricultural societies. Historically, people were more attuned to these astral happenings, as they directly impacted their way of life given the absence of modern light pollution. Over time, Samhain evolved, merging with Christian traditions such as All Souls Day and All Saints Day, eventually transforming into the Halloween we celebrate today.
