Introduction
Greetings, dear readers! As the days grow shorter and the air turns crisp, we find ourselves eagerly anticipating the arrival of autumn. This enchanting season brings with it a myriad of vibrant colors, cozy atmospheres, and cherished traditions. But when exactly does autumn grace us with its presence? Let’s embark on a captivating journey to unravel the answer to the question that’s been on our minds: "Autumn what month?"
The Astronomical Perspective
Equinoxes and Solstices
Autumn’s official commencement is marked by the autumnal equinox, an astronomical event that occurs on September 22 or 23 in the Northern Hemisphere. During this celestial alignment, the sun crosses the celestial equator, resulting in equal lengths of day and night worldwide.
From this point forward, the days in the Northern Hemisphere begin to shorten, while the nights gradually lengthen. Conversely, the Southern Hemisphere experiences the opposite, welcoming the start of spring.
Autumn’s Duration
Astronomically speaking, autumn spans the period from the autumnal equinox until the winter solstice, which falls on December 21 or 22. During this three-month interval, the Earth’s axis tilts away from the sun, causing the days to grow shorter and the nights to grow longer.
The Meteorological Perspective
