After the scorching heat of summer, a slight coolness begins to creep into the air, the sound of Pumpkin Spice Lattes accompanies morning and evening tea, and Halloween decorations appear in the markets, then understand that the most beautiful season of the year, Fall, is about to arrive. And the Fall Equinox officially marks the beginning of this season.
You are absolutely right, there are two Equinoxes in a year: one in March, marking the beginning of spring, and the other in September, marking the beginning of fall. This year, 2026, it will be very special.
When is the Fall Equinox in 2026?
This year, the Fall Equinox will fall on Tuesday, September 22, 2026, in most parts of the United States and Europe. But due to time differences, in India, specifically in your city, Agar, Madhya Pradesh, it will be celebrated on Wednesday, September 23, 2026.
According to Indian Standard Time, this Equinox will occur on the morning of September 23. This day will mark the beginning of Astronomical Fall in the Northern Hemisphere, which will last until December 21, the Winter Solstice.
What is Equinox? Explain in Simple Language
Equinox is made up of two Latin words: Aequus, meaning equal, and Nox, meaning night. This means the day when day and night are approximately equal.
The science is very simple. Our Earth doesn't rotate straight; it's tilted 23.5 degrees. This tilt causes the seasons to change. When the northern part of the Earth is tilted toward the sun, it's summer, and when the southern part is tilted, it's winter.
But there are two days a year when the sun is exactly over the Equator. On those days, no part of the Earth is tilted toward the sun. Therefore, the entire world experiences approximately 12 hours of daylight and 12 hours of nightlight. This is called the Equinox.
A Story of Two Equinoxes
1. March Equinox (around March 20): On this day, the sun crosses the equator from south to north. In the Northern Hemisphere, it is the first day of spring, the beginning of new life after winter. In the Southern Hemisphere, autumn begins on this day.
2. September Equinox (around September 22-23): On this day, the sun moves from north to south. For us, in the Northern Hemisphere, this is the first day of autumn, and in countries like Australia and South America, it is the beginning of spring.
What changes after the Fall Equinox?
After the Equinox, nights become longer than days in the Northern Hemisphere. The sun rises a little later and sets earlier each day. Chlorophyll in tree leaves begins to decrease, causing green leaves to turn yellow, orange, and red, a phenomenon known as Fall Foliage, which people from all over the world travel to the United States, Canada, and Japan to see.
This is the time when farmers harvest their crops, so it's also called the Harvest Season. In ancient times, it was celebrated as Harvest Moon.
How is it celebrated around the world?
Although we don't celebrate it much in India, it has many variations around the world.
In Japan, this day is a national holiday called Higan, where people remember their ancestors. In China, the Mid-Autumn Festival is celebrated, where families eat mooncakes and gaze at the moon. At Stonehenge in England, thousands of people gather to celebrate the sun's setting at the Equator.
In America, it's a cultural phenomenon. This day marks the beginning of Starbucks' Pumpkin Spice Latte, Apple Cider, Bonfire Nights, and preparations for Halloween. Pumpkins are placed outside homes and sweaters are brought out.
Difference between Astronomical Fall and Meteorological Fall
You might be surprised to know that for meteorologists, fall begins on September 1st. This is called Meteorological Fall, which, according to the calendar, occurs from September 1st to November 30th for easier record-keeping.
But what we associate with the Equinox is Astronomical Fall, which is based on the actual position of the Sun and Earth. Therefore, festivals and culture always adhere to the Astronomical date.
Why will Fall 2026 be special?
According to the Meteorological Department, this year, due to La Niña, Fall may be slightly colder and longer. Fall foliage in the United States will peak a week later, meaning the most beautiful view will be seen in the second week of October.
So, if you want to fully enjoy the fall of 2026, mark September 23rd on your calendar. Wake up early that day and witness the magical balance of day and night, and welcome this new season with a hot Pumpkin Spice Latte in the evening. After that, the long winter nights are about to begin.
