For students, planners, and the general public, the onset of fall signals changes in weather, agriculture, and social activities.

Abstract The question "What month is fall in America?" does not have a single answer. In the United States, the timing of autumn (fall) is defined by three distinct systems: astronomical seasons based on Earth's orbit, meteorological seasons based on annual temperature cycles, and cultural definitions tied to holidays and commerce. This paper examines each framework, concluding that while September, October, and November are the core fall months, the start date varies from September 1 (meteorologically) to mid-to-late September (astronomically) to after Labor Day (culturally). what month is fall in america
