What is the First Day of Fall?

The first day of fall is defined by the fall equinox, a day when the sun crosses the celestial equator, resulting in nearly equal lengths of day and night. This seasonal shift occurs around September 22 or 23 in the northern hemisphere, marking the transition from summer to autumn.

Why Does the Fall Equinox Happen?

The reason behind the fall equinox is the earth's axial tilt. As the earth orbits the sun, different areas receive varying amounts of sunlight throughout the year. During the equinox, sunlight hits the equator directly, leading to a balance of light that heralds the arrival of autumn.

What to Look for During the Autumn Season

The shift in animal behavior as many prepare for winter.
