City solar dossier
These rows bind the page to Anchorage's coordinates, local timezone, annual daylight spread, twilight availability, and peer-city curve rather than a reusable sunrise template.
Anchorage is computed at 61.22°N, 149.90°W in America/Anchorage. The coordinate, not the country or timezone alone, controls the curve.

Solar evidence pack
This audit ties the page to a retained city route, exact coordinates, local timezone, a full-year daylight curve, twilight thresholds, and peer-city comparisons.
/sun/anchorage/ resolves to Anchorage, United States; the route is generated only from the retained SUN_CITIES list.
61.22°N, 149.90°W; latitude band high-mid latitude band; Northern Hemisphere.
America/Anchorage is used to anchor today's local sunrise, sunset, solar noon, and twilight windows.
365 daily daylight rows were computed for 2026; expected 365.

Practical read
Photography
4h 42m golden hour today
Best annual golden-hour day: Dec 8 — 6h 36m. Blue-hour total today: 2h 58m.
Astronomy
236 true-darkness days
Longest astronomical-night entry: Dec 21 — 12h 41m. Use local cloud cover and moon phase separately.
Outdoor routine
19h 3m daylight today
Sunrise 4:27 AM and sunset 11:29 PM are the practical day-boundaries for school runs, work windows, and outdoor activity.
Seasonal planning
13h 55m annual swing
June average 19h 12m; December average 5h 38m. This is the year-scale gap to check before travel or outdoor scheduling.
Travel comparison
10 retained peer curves
Anchorage's closest daylight-pattern peers here include Stockholm (12h 32m annual swing), Reykjavík (17h 2m annual swing), Moscow (10h 33m annual swing), Ushuaia (10h 8m annual swing).
Civil-light risk
27 civil white-night days
Civil twilight uses -6°. White-night counts matter because dawn/dusk phases stop behaving like ordinary morning/evening windows.
Calculation boundaries
What this model includes
Latitude, longitude, solar elevation thresholds, atmospheric-refraction sunrise/sunset convention, America/Anchorage local formatting, and a 365-day sweep for 2026.
What this model excludes
Mountains, skyline obstruction, sea horizon differences, weather, smoke, cloud cover, local legal definitions, aviation rules, and observer elevation.
When to verify elsewhere
Use official observatory, aviation, maritime, legal, or local almanac sources for high-stakes operations; this page is designed for planning, comparison, and general reference.
Why city pages differ
Two cities in America/Anchorage can still have different daylight and twilight curves because the coordinate pair, especially latitude, drives the result.
Seasonal daylight fingerprint
These values are derived from the same 365-day curve: threshold counts, fastest day-to-day change, the closest 12-hour balance, and monthly daylight averages.

Year-round photographer planning
Combined morning + evening windows, computed for every UTC day of the year.
White-night counts
27 days without civil-twilight bound, 91 without nautical-twilight bound, 129 without astronomical-twilight bound. On those days the sun never gets low enough for the named phase to occur, so true darkness disappears for that stretch.
Twilight phases reference
Solar elevation thresholds used on this page. All angles are measured from the true horizon at the city coordinate.
Sunrise / sunset · -0.833°
The sun's upper edge crosses the horizon. The negative value is atmospheric refraction (~34') plus the apparent solar disc radius (~16') — what almanacs call "official" sunrise/sunset.
Golden hour · 6° to -4°
Warm, low-angle light photographers and cinematographers plan around. Two windows per day — one in the morning, one in the evening.
Blue hour · -4° to -6°
Sky takes on deep, even blues; useful for cityscape photography because artificial lights and ambient sky balance.
Civil twilight · -6°
Brightest natural objects are still visible; outdoor activities don't need artificial light. Used in many legal definitions of dawn/dusk.
Nautical twilight · -12°
Horizon is just visible at sea, allowing celestial navigation; named for sailors taking sextant fixes.
Astronomical twilight · -18°
Sky is dark enough for deep-sky observation. After astronomical dusk and before astronomical dawn is when astrophotographers shoot.

Reference fields include Anchorage's route, coordinates, timezone, daylight extremes, twilight windows, white-night counts, peer curves, evidence checks, and calculation boundaries.
Frequently asked questions
These are selected by latitude and annual daylight swing, not by the generic city list, so the comparison is tied to Anchorage's actual solar profile.
