Ask most people when the earliest sunset of the year happens and they'll say the winter solstice. It sounds right — the solstice is the shortest day, so surely that's when the sun clocks out earliest.

It isn't. In New York, the sun sets at 4:28 p.m. in early December and stays within a minute of that for about ten days. By the solstice on December 21, sunset has already drifted back to 4:31 p.m. The evenings are getting longer before the shortest day arrives.

This quirk of sun mechanics affects photographers, commuters, runners, and anyone who plans their day around daylight. Here's what's actually happening, with real dates for major cities.

The Short Answer

The earliest sunset of the year lands in late November or early December for most of the United States — roughly two to four weeks before the December solstice. The latest sunrise follows the same trick in reverse, arriving in early January, after the solstice has passed.

That means the solstice only owns one record: the shortest total day. The darkest evening and the darkest morning each belong to different dates.

Why the Earliest Sunset Isn't on the Shortest Day

Two separate clocks are fighting each other in December: the length of the day, and where noon sits on your watch.

Reason 1: Solar days run long in December. A "day" as your clock measures it is exactly 24 hours. But the time it takes the sun to return to its highest point in the sky — a solar day — is not constant. Earth's axis is tilted 23.4 degrees, and its orbit is an ellipse, not a circle. In December, near perihelion (our closest approach to the sun, in early January), Earth moves fastest along its orbit. The combination stretches the solar day to about 24 hours and 30 seconds.

Reason 2: Solar noon drifts later. Those extra ~30 seconds accumulate daily. Through November and December, solar noon — the moment sunrise and sunset are symmetric around — slips about 10 minutes later on the clock between early December and the solstice. You can see this drift yourself with a solar noon calculator: in early December, solar noon in New York hits around 11:52 a.m. local time; by late December it's past noon.

Now put the two effects together:

Sunset = solar noon + half the day length
The day length keeps shrinking until December 21 (pulling sunset earlier)
But solar noon keeps drifting later (pushing sunset later)

In early December, the shrinking-day effect runs out of steam, while the drifting-noon effect keeps pushing. The two cancel out, sunset bottoms out — and then starts moving later even as the days are still getting shorter. The same math pushes sunrise later on both ends, which is why the latest sunrise doesn't arrive until early January.

Astronomers call the gap between clock time and sun time the equation of time, and it swings roughly 16 minutes across the year. That 16 minutes is the entire reason your darkest evening misses your shortest day.

Earliest Sunset Dates for 8 Major Cities

Computed with the same NOAA-based solar algorithm this site uses for its sunrise and sunset calculator. Sunsets in this window move by less than a minute over many days, so think of each date as the center of a flat stretch:

New York: 4:28 p.m., bottoming around Dec 3–13. Solstice sunset: 4:31 p.m.
Chicago: 4:19 p.m., around Dec 3. Solstice sunset: 4:22 p.m.
Denver: 4:35 p.m., around Dec 1. Solstice sunset: 4:38 p.m.
Seattle: 4:17 p.m., around Dec 7. Solstice sunset: 4:20 p.m.
Los Angeles: 4:43 p.m., around Nov 29–Dec 10. Solstice sunset: 4:47 p.m.
Houston: 5:21 p.m., around Nov 28. Solstice sunset: 5:26 p.m.
Phoenix: 5:20 p.m., around Nov 27. Solstice sunset: 5:24 p.m.
Miami: 5:29 p.m., around Nov 22–early Dec. Solstice sunset: 5:34 p.m.

The 2026 solstice arrives December 21 at 20:50 UTC — 3:50 p.m. Eastern, 12:50 p.m. Pacific.

The Pattern: Latitude Changes Everything

Look closely at the list above and a pattern emerges: the further south you are, the earlier your earliest sunset arrives.

Seattle (47.6°N) bottoms out around December 7, only about two weeks before the solstice.
Miami (25.8°N) bottoms out in late November — nearly four weeks before the solstice.

At higher latitudes, day length changes fast (Seattle loses from 15+ hours of summer light down to about 8 hours 25 minutes on the solstice). That steep shrink dominates the equation-of-time drift longer, so the sunset minimum hangs on until closer to the solstice. Near the equator, day length barely changes at all, so the drifting noon wins early and the whole sunrise/sunset cycle locks to the equation of time instead.

The same latitude logic flips for sunrises: the latest sunrise in Seattle arrives around December 27, barely off the solstice, while Miami's darkest morning waits until about January 11.

If you want your own city's numbers — day length on any date, and how much daylight you're gaining or losing each day — the day length calculator shows the full year curve for any location.

The Latest Sunrise: January's Hidden Bonus

Here's the practical payoff of this asymmetry, and it's genuinely good news for morning people:

The gap between the solstice and the latest sunrise means mornings keep getting darker for another week or two after December 21 — but evenings are already growing fast. From mid-December through early January, New York gains evening light at the same time it's still losing morning light. Total daylight is increasing; it's just being delivered unevenly.

Runners and cyclists feel this first: by January 5, New York's sunset has pushed past 4:38 p.m., while sunrise is still around 7:20 a.m. You get a visibly brighter evening commute weeks before your morning commute improves.

Photographers get a parallel gift. The flattest, warmest low-angle light of the day comes around dawn and dusk, and the golden hour calculator shows how those windows shift across the season — in December, evening golden hour starts before 4 p.m. in most northern cities.

How to Check Your Exact Location

City tables are averages — your exact earliest sunset depends on your latitude, longitude, and time zone, and it can differ by several days even within one metro area. To get precise numbers:

Enter your city or coordinates into the sunrise and sunset calculator and scan the December table — look for the row where sunset time stops decreasing.
Check the day-by-day delta if you care about the rate of change — early December evenings gain seconds per day; by mid-January it's more than a minute per day.
Everything is computed in your browser with the NOAA solar algorithm, standard at ±1 minute for most locations.

One more seasonal note for 2026: daylight saving time ends November 1, which artificially yanks sunsets an hour earlier right before this whole minimum arrives. If the first week of November feels brutally dark, that's the clock change, not the sun — the sun's own earliest sunset doesn't hit for another month.

FAQ

Is the earliest sunset on the winter solstice? No. For most of the US, the earliest sunset falls two to four weeks before the solstice — in late November or early December. The solstice is the shortest total day, but the earliest sunset and latest sunrise each fall on separate dates around it.

Why is the earliest sunset in early December? Because solar noon drifts about 10 minutes later on clocks between early December and the solstice, offsetting the still-shrinking day length. Sunset stops getting earlier once those two effects cancel out — usually the first week of December at mid-northern latitudes.

When is the latest sunrise of the year? For most US locations, the latest sunrise arrives between late December and early January — after the solstice. At higher latitudes (Seattle, Minneapolis) it's within days of December 21; further south (Miami, Houston) it can be one to two weeks into January.

What is the equation of time? The difference between clock time and apparent solar time, caused by Earth's axial tilt and its elliptical orbit. It swings roughly ±16 minutes across the year and is the reason solar noon isn't at 12:00 on your watch — which is what desynchronizes the earliest sunset and latest sunrise from the solstice.

When do days start getting longer? Total day length starts growing immediately after the winter solstice on December 21, 2026 (20:50 UTC). But evenings start getting longer earlier — right after your location's earliest sunset in early December — while mornings keep darkening until early January.
