What is the first day of fall called?

• A. Winter Solstice
• B. September Equinox
• C. Vernal Equinox
• D. Summer Solstice

Answer: (B)

The first day of fall is known as the September Equinox, which occurs around September 22 or 23 each year in the Northern Hemisphere. This event marks the point when day and night are approximately equal in length, signifying the transition from summer to autumn. The September Equinox is significant in many cultures and is often associated with harvest festivals, as it indicates a change in weather patterns and daylight hours. During this time, the sun crosses the celestial equator, moving southward, which results in cooler temperatures and shorter days as we approach winter. In contrast, the other terms listed refer to different seasonal transitions: the Winter Solstice marks the start of winter; the Vernal Equinox signifies the beginning of spring; and the Summer Solstice represents the height of summer. Each of these events has its own unique significance in the seasonal calendar, but none align with the start of fall as accurately as the September Equinox.
