When Does Autumn Begin? Fall Season Dates
As summer days dwindle and a cooler breeze begins to stir, many eagerly anticipate the arrival of autumn. Known for its vibrant foliage, cozy atmosphere, and the start of the holiday season, autumn holds a special place in many hearts. But when exactly does this cherished season begin?
The First Day of Autumn: Defined by the Equinox
The first day of autumn in the Northern Hemisphere is marked by the autumnal equinox. This is the moment when the sun crosses the celestial equator—an imaginary line in the sky above the Earth's equator—from north to south. On this day, both the Northern and Southern Hemispheres receive roughly equal amounts of daylight and darkness.
- Typically, the autumnal equinox occurs on September 22 or 23.
- However, the exact date can vary slightly each year due to the Earth’s elliptical orbit and how the calendar is structured.
Why is it Called an Equinox?
The term "equinox" comes from the Latin words "aequi" (equal) and "nox" (night). This reflects the nearly equal duration of day and night on the equinox. While the day and night aren't exactly 12 hours each due to atmospheric refraction of sunlight, they are closer to equal on this day than at any other time of the year. — Forrest Gump Wave GIF: Find The Perfect Reaction
Autumn Beyond the Calendar: A Seasonal Shift
While the autumnal equinox provides a specific date for the start of autumn, the experience of the season can vary widely depending on geographic location. In some regions, the leaves may start changing color weeks before the equinox, while in others, the full splendor of fall foliage may not appear until well into October.
Meteorological Autumn vs. Astronomical Autumn
It's worth noting that meteorologists define autumn differently. Meteorological autumn always begins on September 1 and ends on November 30. This fixed date helps in comparing seasonal statistics and climate data more consistently. — MLB 2025 Playoff Bracket: Early Predictions
