Fall 2023 Begins September 23 Fall, or autumn, in 2023 started on Saturday, September 23 , marking the autumnal equinox when day and night are nearly equal in length.

Astronomical vs. Meteorological Start

Astronomers define fall by the Earth's tilt and orbit, pinpointing the equinox at 2:50 a.m. ET on September 23, 2023, transitioning from summer to the cooler season ahead. Meteorologists, however, use a fixed calendar: September 1 to November 30, aligning with temperature patterns for easier forecasting. This dual approach sparks friendly debates—imagine astronomers gazing at stars while meteorologists check thermometers!

Why That Exact Date?

The equinox occurs when the sun crosses the celestial equator, a cosmic handoff from northern summer to winter. In 2023, it hit precisely at 2:50 a.m. ET (06:50 UTC), ushering in crisp air, colorful foliage, and harvest vibes worldwide. Northern Hemisphere folks celebrated with pumpkin spice everything, while the Southern Hemisphere welcomed spring.
