September’s Fall Equinox Is Coming: What to Know and What It Looks Like

Later this month, you could experience an equinox sunrise, which marks the arrival of fall in the Northern Hemisphere.

Labor Day has come and gone, and school is back in session. Though the leaves have yet to start turning, fall is making its way here. The official arrival of the season is the autumnal equinox, which occurs in the Northern Hemisphere in September.

After a hot summer, the fall 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 fall 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 does the September 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.

What is the fall 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.

How is equinox different from 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.

See equinoxes 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.

How to celebrate the fall 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.

OnePlus and Oppo to Raise Smartphone Prices as Memory Costs Climb

Oppo says rising costs for key phone components will trigger price adjustments on some devices starting March 16.

Chinese smartphone-makers OnePlus and Oppo plan to raise prices on some existing models starting next week, according to a 9to5Google report citing GizmoChina and a notice posted on Oppo’s China online store.

In its notice, Oppo said it would adjust pricing after evaluating rising costs for several key components used in its mobile phones. The changes are expected to take effect around March 16 and will affect some of the company’s more affordable smartphones, as well as some OnePlus models.

Flagship devices — like those in the Find and Reno series — are not expected to be affected for now. The reported adjustments currently appear to be limited to China.

The move highlights growing pressure across the smartphone supply chain as component costs climb. Analysts say prices for memory and storage chips used in phones have been rising in recent months as demand surges across the tech industry.

Much of the chip demand is coming from the rapid buildout of AI data centers, which rely on large amounts of high-performance memory.

That pressure isn’t limited to Oppo and OnePlus. Analysts say smartphone brands across the industry are facing rising component costs amid increased demand for memory chips.

As manufacturers shift production toward higher-margin memory used in AI servers, supply for consumer electronics such as smartphones and laptops can tighten.

If component costs continue to rise, manufacturers may face difficult choices later this year, including raising retail prices or adjusting device specifications to offset higher manufacturing costs.

OnePlus and Oppo didn’t immediately respond to a request for comment.

Harvard Business Review Study Finds ‘AI Brain Fry’ Is Leaving Workers Mentally Fatigued

Study participants reported increased mental fatigue while using AI tools, but less burnout overall.

Workers who excessively use AI agents and tools at work are at increased risk of mental fatigue, according to a recent Harvard Business Review study. In certain industries, more than 25% of hired professionals report increased mental strain due to their role in AI oversight — though these professionals also generally experienced less burnout than peers who aren’t using AI.

This phenomenon — which the researchers refer to as «AI brain fry» — is described as a «‘buzzing’ feeling or a mental fog» that caused study participants to develop headaches and difficulty focusing and making decisions. Individuals pointed to being overwhelmed by large amounts of information and to frequent task switching as the reasons for these feelings.

Studied individuals experienced more brain fry when they utilized AI agents to manage a workload beyond their own cognitive capacity. When participants used AI to replace mundane, repetitive tasks, managing the growing number of tools led to increased mental fatigue.

Crucially, the study found that fewer individuals who used these AI agents reported workplace burnout.

The researchers predict that this is because burnout testing assesses emotional and physical distress. In contrast, they report, acute mental fatigue «is caused by marshalling attention, working memory and executive control beyond the limited capacity of these systems.»

These are the processes that are taxed when study participants use multiple AI tools in their workflow, according to the researchers.

The Harvard study identifies several business costs incurred by workers suffering from AI brain fry. The foremost consequence is that these individuals may end up making lower-quality decisions. «Workers in [the] study who endorsed AI brain fry experience 33% more decision fatigue than those who did not,» the study reports. Workers who report AI brain fry were also more likely to self-report making both minor and major errors at their jobs.

Another recent Harvard Business Review study similarly found that employees who use AI tools «worked at a faster pace, took on a broader scope of tasks and extended work into more hours of the day,» but warned that «workload creep can in turn lead to cognitive fatigue, burnout and weakened decision-making.»
