How long will a 2023 equinox last?
The equinox is a precise moment in time, not a long event: the Sun’s center crosses the celestial equator, and the transition lasts only a few minutes as the Sun’s disk slides across the line. In 2023 there were two equinoxes—vernal (spring) around March 20 and autumnal (fall) around September 23—with the exact moment depending on time zone. On or near these dates, daylight is generally close to 12 hours, though the precise length varies by latitude and local horizon geometry.
Understanding what an equinox means
In astronomical terms, an equinox marks the moment when the Sun is exactly above the Earth's equator, causing nearly equal day and night lengths. Because the Sun has a finite size in the sky, observers may notice the transition spanning a couple of minutes as the Sun’s disk crosses the celestial line.
Why the moment is brief
The Sun’s apparent diameter is about half a degree, and the Earth rotates at roughly 15 degrees per hour. That means the Sun crosses the equator line in about two minutes, though the exact duration can vary slightly depending on location and whether you measure the moment of the center crossing or the first/last contact of the solar disk.
Key 2023 equinox dates
Here are the two equinox moments that defined 2023. Note that calendar dates can shift by time zone, so local calendars may reflect slight differences.
- Vernal (spring) equinox — around March 20, 2023 (date varies by time zone).
- Autumnal (fall) equinox — around September 23, 2023 (date varies by time zone).
In practice, the equinox is a precise moment in time; the daylight pattern around those dates is typically close to 12 hours, with slight variations by latitude and local topography.
Impact on daylight and how people observe it
While the equinox moment itself is brief, it signals a shift in daylight balance. Regions near the equator experience roughly 12 hours of daylight year-round, while higher latitudes see more pronounced seasonal changes. The sunrise and sunset times on or near the equinoxes are unusually even, though exact daylight length still depends on your geographic location.
Summary
In 2023, there were two equinoxes: the vernal equinox around March 20 and the autumnal equinox around September 23. The equinox is defined as the instant the Sun’s center crosses the celestial equator and lasts only a few minutes as the Sun’s disk passes the line. Daylight around these dates is typically near 12 hours, with small variations by latitude and local conditions.
What is the Equinox's predicted lifespan?
Average Lifespan in Miles and Years
Newer Equinox models usually hit 100,000-150,000 miles before needing big repairs. But, we've seen some go over 200,000 miles with the right care.
What is the average life expectancy of a Chevy Equinox?
A Chevy Equinox can last 200,000 to 250,000 miles with proper maintenance, which is equivalent to about 13 to 17 years of average driving. The lifespan depends on regular maintenance, driving habits, and the specific model year, with later models generally showing better reliability. Factors like regular oil changes, timely repairs, and smooth driving habits can help extend the vehicle's life.
Factors that influence lifespan
- Regular maintenance: Following the recommended maintenance schedule, including oil changes, tire rotations, and filter replacements, is crucial for longevity.
- Driving habits: Smooth acceleration and braking put less stress on the engine and other components compared to aggressive driving. Frequent highway driving is also less stressful than stop-and-go city driving.
- Model year: Newer models (2018 and later) generally have better reliability ratings compared to older generations, which had some known issues, particularly with the four-cylinder engine in the 2010-2017 model years.
- Repairs: Addressing problems promptly can prevent minor issues from becoming major, costly repairs down the road.
- Engine choice: Some owners report good longevity with the V6 engine, while newer turbocharged four-cylinders in newer models are also considered reliable options.
How many miles will a 2023 Chevy Equinox last?
200,000 miles
A Chevy Equinox can last 200,000 miles or more with proper care. Some owners even report reaching 250,000 miles. If you drive around 15,000 miles per year, this means your Equinox could last 13 to 17 years before needing major repairs.
What year of Equinox to stay away from?
You should stay away from the Chevy Equinox years of 2005–2008 and 2010–2017 due to recurring issues like engine problems (especially excessive oil consumption), head gasket failures, and other mechanical failures. Other years with reported problems include 2018, due to recalls and other issues, and the recent 2025 model, which is criticized for its weak engine and CVT.
Model years to avoid
- 2005–2008: These early models are prone to serious engine issues, including head gasket failure and cooling system problems, which can lead to costly repairs and overheating.
- 2010–2017: This generation is particularly problematic, with widespread complaints about excessive oil consumption, engine stalling, and potential engine damage.
- 2018: This year had specific recalls and reported issues, including problems with the right front intermediate drive shaft that could cause a loss of propulsion.
- 2019–2023: While some models in this range are considered good, this period saw several recalls and issues with the StabiliTrak system, fuel pumps, and brake calipers.
- 2025: The redesigned model has been criticized for a weak 1.5L engine and CVT transmission.
How to stay safe
- Be cautious: If you are considering a used Equinox, it's crucial to get a thorough inspection by a trusted mechanic before buying.
- Look for alternatives: If your budget allows, consider skipping these years altogether and looking at the 2015-2017 or 2019-2020 models, which are generally considered more reliable.
- Consider a Certified Pre-Owned (CPO) vehicle: A CPO model may come with a warranty and has undergone a detailed inspection, which can provide peace of mind.
- Monitor key components: For any Equinox, keep an eye on the oil level and schedule regular oil changes with high-quality lubricants to help mitigate engine wear.
