While popular culture frequently equates summer with the solstice—the longest day of the year—operational sciences and societal planning rely on the meteorological definition, which fixes the season’s start on June 1st in the Northern Hemisphere. This paper explores the scientific basis for both definitions, examines the phenological indicators that signal the season’s arrival, and analyzes the cultural significance of this temporal transition.
