City solar dossier

Rome daylight facts that are not generic

These rows bind the page to Rome's coordinates, local timezone, annual daylight spread, twilight availability, and peer-city curve rather than a reusable sunrise template.

Coordinate model

Rome is computed at 41.90°N, 12.50°E in Europe/Rome. The coordinate, not the country or timezone alone, controls the curve.

Annual daylight spread

6h 7m between Dec 20 (9h 7m) and Jun 18 (15h 14m).

Local-date snapshot

Today resolves to sunrise 6:47 AM, solar noon 11:53 AM, and sunset 4:59 PM.

Photographer signal

golden hour today 1h 56m; blue hour today 22m; longest golden-hour day Dec 21 — 2h 9m

Darkness and white-night risk

365 days include astronomical darkness; 0 civil white-night days and 0 astronomical white-night days are modeled in 2026.

Practical read

How to use this solar profile

Photography

1h 56m golden hour today

Best annual golden-hour day: Dec 21 — 2h 9m. Blue-hour total today: 22m.

Astronomy

365 true-darkness days

Longest astronomical-night entry: Dec 21 — 11h 31m. Use local cloud cover and moon phase separately.

Outdoor routine

10h 12m daylight today

Sunrise 6:47 AM and sunset 4:59 PM are the practical day-boundaries for school runs, work windows, and outdoor activity.

Seasonal planning

6h 7m annual swing

June average 15h 11m; December average 9h 11m. This is the year-scale gap to check before travel or outdoor scheduling.

Travel comparison

10 retained peer curves

Rome's closest daylight-pattern peers here include Chicago (6h 6m annual swing), New York (5h 51m annual swing), Madrid (5h 47m annual swing), Toronto (6h 31m annual swing).

Civil-light risk

Full civil-twilight bound all year

Civil twilight uses -6°. White-night counts matter because dawn/dusk phases stop behaving like ordinary morning/evening windows.

Calculation boundaries

What this model can and cannot promise

What this model includes

Latitude, longitude, solar elevation thresholds, atmospheric-refraction sunrise/sunset convention, Europe/Rome 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 Europe/Rome can still have different daylight and twilight curves because the coordinate pair, especially latitude, drives the result.

Seasonal daylight fingerprint

How daylight changes through 2026

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.

Twilight phases reference

What each phase means

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.

Solar planning depth

What the Rome daylight curve means

This section turns the chart into readable planning context: latitude, seasonal range, monthly checkpoints, and how the curve should be used.

Solar fingerprint

Rome, Italy is modeled at 41.90°N, 12.50°E in Europe/Rome. That coordinate pair drives every bar in the 2026 daylight curve.

Seasonal swing

The longest day is Jun 18 at 15h 14m; the shortest is Dec 20 at 9h 7m. The yearly range is 6h 7m, which makes this a moderate seasonal daylight profile.

Latitude context

Rome sits in the Northern Hemisphere mid-latitude band. Latitude is the main reason two cities in the same timezone can have very different sunrise, sunset, and day-length patterns.

Monthly anchors

Useful checkpoints in this curve: Jan 15 9h 28m, Mar 15 11h 54m, Jun 15 15h 13m, and Sep 15 12h 30m. These anchors help readers see the shape of the year without reading all 365 bars one by one.

Today and twilight

Today in Rome, sunrise is about 6:47 AM, sunset about 4:59 PM, solar noon 11:53 AM, and daylight totals 10h 12m. Civil twilight runs 6:18 AM to 5:28 PM; golden hour windows are 6:29 AM to 7:27 AM and 4:19 PM to 5:17 PM.

Golden hour planning

Today's combined morning + evening golden hour totals 1h 56m. The longest combined golden hour day of 2026 is Dec 21 — 2h 9m. The shortest non-zero day is Mar 22 — 1h 48m. Year-round average is 1h 57m per day across days where a golden-hour window exists.

Twilight ladder

Nautical twilight today: 5:45 AM to 6:02 PM. Astronomical twilight today: 5:12 AM to 6:34 PM. The single longest stretch of true astronomical darkness in 2026 occurs on Dec 21 — 11h 31m. 365 days in 2026 include at least some astronomical darkness.

Seasonal momentum

Fastest daily daylight gain: Jan 30 (+3m from the previous day). Fastest daily daylight loss: Aug 4 (-3m from the previous day). Closest 12-hour balance: Mar 17 at 12h (no change from 12h). Average-month anchors: June average 15h 11m is brightest, while December average 9h 11m is shortest. 105 days reach 14h+ daylight; 82 days stay at 10h or less.

Blue and civil light

Today's combined blue hour totals 22m. The longest combined blue-hour day is Jun 21 — 27m. Blue-hour average is 24m per usable day. The longest civil-twilight-only day is Jun 21 — 1h 9m. Civil twilight averages 1h 1m where both dawn and dusk edges exist.
Sunrise and sunset are approximations for planning and comparison. For legal, aviation, photography, or scientific use, verify with a local almanac or official observatory source.
