Autumn Equinox Is in Two Weeks: What It Is and What It Looks Like

Experience an equinox sunrise later this month, which marks the arrival of fall in the Northern Hemisphere.

Even if the leaves haven’t yet begun turning where you live, Labor Day is over, school is back in session and fall is almost here. The official arrival of the season is the autumnal equinox, which occurs in the Northern Hemisphere this month.

After a hot summer, the September equinox marks a welcome shift in the seasons for many folks. But what exactly is an equinox? It’s all about Earth and its relationship with the sun. Here’s how to understand, visualize and celebrate the autumnal equinox.

When is the autumn equinox?

This year, the autumnal equinox in the Northern Hemisphere falls on Monday, Sept. 22. If you want to be extra specific and mark it on your calendar, mark it for 11:19 a.m. PT.

Dates can shift slightly for equinoxes depending on the year, but it’s always around this time in September. The next vernal equinox in the Northern Hemisphere takes place on March 20, 2026, and will mark the start of spring.

What is the autumn equinox?

The meaning of equinox is right there in the name: a combination of the Latin words for equal and night.

«There are only two times of the year when the Earth’s axis is tilted neither toward nor away from the sun, resulting in a ‘nearly’ equal amount of daylight and darkness at all latitudes,» the National Weather Service said in an explainer about the seasons.

The Earth spins on an axis (imagine a line running from pole to pole) and the planet sports a jaunty 23.5-degree tilt. The tilt is what gives us seasons. As the Earth orbits the sun, the tilt means some areas of the planet get more direct sunlight than others. That’s how it can be summer in the Northern Hemisphere (tilted toward the sun) and winter in the Southern Hemisphere (tilted away from the sun) at the same time. During the equinox, the sun shines straight at the equator and gives equal love to the two hemispheres.

Other planets that are also tilted on their axes of rotation also experience equinoxes. The time scales can be very different, however. An equinox on Saturn only comes around about every 15 Earth years. That means each season lasts for over seven years on Saturn. It’s even wilder on Neptune, which has seasons that last decades. We can be grateful for the relatively short seasons on our planet.

What does an equinox look like?

Wherever you are on Earth on the day of the equinox (and whether it’s a spring or fall equinox, depending on which hemisphere you live in), the sun will rise as close to east and set as close to west as possible, making it a foolproof compass. Go outside and watch the sunset and sunrise, and make a note of the landmarks in front of the sun. That way, you’ll always know what exactly is west and east.

The two annual equinoxes also feature the fastest sunrise and sunset of the year, with the sun taking just a few seconds to appear and disappear. That’s because this is the steepest angle at which the sun rises and sets during the year.

How is an equinox different from a solstice?

As with equinoxes, solstices are associated with Earth’s tilt, but instead of daylight and nighttime being even, the days and nights are at their extremes. The winter solstice is the shortest day of the year, while the summer solstice is the longest. This year, the winter solstice for the Northern Hemisphere falls on Sunday, Dec. 21.

What does the equinox look like from space?

Earth-watching satellites up in orbit have a unique view of the equinox. A NASA Earth Observatory video shows Earth from space and how the positioning of the sun’s light shifts with the changing of the seasons. It’s a great way to visualize what’s happening during our planet’s orbit around the sun.

Celebrating the equinox

Equinoxes aren’t like eclipses or meteors. There isn’t a big wow moment when you see something spectacular. The fall equinox this year will look like any other day, but it’s a handy way to mark the changing of the astronomical seasons. You can go around and declare, «It’s officially the first day of autumn!» How you celebrate is up to you. Here’s a suggestion: Put on your favorite sweater, go for a scenic foliage drive and sip a pumpkin spice latte to welcome fall in style.

The Top Android Phones of 2026 Could Get Better AI With Arm’s New CPUs

The next generation of Arm’s CPUs, used in phones from Samsung and others, feature higher AI performance than last year’s.

On the same day Apple revealed its new iPhone 17 lineup, chip designer Arm is introducing its next generation of processors bundled into its new Arm Lumex platform. These processors will likely make their way into premium Android phones coming in 2026 — and improve their AI capabilities without draining device batteries faster, Arm says.

«It’s pretty amazing how there’s been kind of this insatiable amount of performance being asked for [by our customers], and a lot of it’s around AI, as well as some graphics workloads,» said Chris Bergey, senior vice president and general manager of Arm’s client line of business.

Arm’s processors have traditionally been the centerpieces of holistic systems-on-a-chip, which power smartphones. For instance, Arm’s previous top-end central processing unit, the Cortex X925, released last year, is featured in Samsung’s Exynos 2500 chipset, which powered the Galaxy Z Flip 7 and MediaTek’s Dimensity 9400 chipset, found in the Oppo Find X8 Pro.

It’s likely that Arm’s new chips, either on their own or bundled into the company’s Arm Lumex platform, will power premium Android phones and other devices next year. But it faces more competition as Qualcomm (which used Arm CPUs in older chips like the Snapdragon 8 Gen 3) has shifted to its internally designed Oryon CPUs in its latest silicon — which was the subject of its own tech licensing clash over the last few years between the two chip companies.

Arm’s new CPU range has shifted with a new naming paradigm. The successors to the X925 are two different chips: the highest-end C1-Ultra, which boasts 25% greater performance over its predecessor, and the next-most-powerful C1-Premium (no performance improvement given). The successor to the A725 chip is the C1-Pro, which has 12% greater efficiency.

These CPUs also benefit from an evolution of their chip architecture called Scalable Matrix Extension version 2, which enables better AI performance.

The new Arm Lumex platform combines these chips with the new Mali G1-Ultra GPU (which Arm says has 20% better performance and twice the ray tracing as its predecessor) for a system that can be plugged into larger chipsets. The end result: up to 5x improvement in AI performance, 4.7x lower latency for speech-based workloads (think live translation) and 2.8x faster audio generation, Arm says.

The goal is faster performance without increasing the battery drain when running AI tasks that tax processing power. For example, a yoga tutor demo app running Arm’s new chips saw a 2.4x boost in text-to-speech to give faster feedback to users, the company said in a press release.

As a supplier of chips and technology, it’s ultimately up to the phonemakers using Arm’s silicon to decide how much (or little) of the advancements they integrate into their devices. But as demand for generative AI like ChatGPT increases, so too does the drive to get that functionality working on phones as efficiently as possible, rather than relying on slower responses going to and from the cloud. So what will consumers see with devices running C1-Ultra chips and Arm’s new technology?

«I think what they’re gonna see is the ability to run amazing on-device AI and to do so with significant power savings, significant performance increases, and also third-party support,» Bergey said. «Not just first-party devices, but also third-party devices.»
