The crisp air, colorful leaves, and cozy sweaters all signal the arrival of fall. Also known as autumn, this season is one of the most beloved times of the year. But what makes fall 2025 special, and when exactly does the season begin? In this guide, we’ll cover the first day of fall 2025, the difference between “fall” and “autumn,” fun seasonal facts, and ways to celebrate the season.
When Is the First Day of Fall 2025?
The first day of fall 2025 in the Northern Hemisphere is Monday, September 22, 2025. This date marks the autumn equinox, when day and night are nearly equal in length. From this point forward, days gradually become shorter and nights longer. The autumn equinox 2025 is not only a scientific event but also a cultural celebration. Many people share “Happy Autumn Equinox” blessings, enjoy seasonal traditions, and welcome the beauty of cooler days.
Fall or Autumn: Is There a Difference?
One of the most common seasonal questions is: Is fall the same as autumn? The answer is yes—both words refer to the same season.
- Autumn is the older term, rooted in Latin and used mainly in British English.
- Fall became popular in American English, derived from the phrase “fall of the leaves.”
So if you’re wondering, “is autumn or fall correct?” the truth is that both are right. It’s just a matter of regional preference.
Why Do Leaves Change Color in the Fall?
One of the most iconic parts of the fall season is watching the leaves turn brilliant shades of red, orange, and yellow. But why does this happen? As daylight shortens, trees stop producing chlorophyll, the green pigment that helps with photosynthesis. Without it, other pigments like carotenoids and anthocyanins become visible, creating the stunning autumn leaves we all love. This natural transformation is one of the reasons people celebrate fall with phrases like “Happy 1st Day of Fall” and share welcome fall images across socia media.
