Practical read
How to use this solar profile
Photography
1h 29m golden hour today
Best annual golden-hour day: Dec 21 — 1h 34m. Blue-hour total today: 18m.
Astronomy
365 true-darkness days
Longest astronomical-night entry: Dec 21 — 10h 25m. Use local cloud cover and moon phase separately.
Outdoor routine
11h 23m daylight today
Sunrise 6:40 AM and sunset 6:03 PM are the practical day-boundaries for school runs, work windows, and outdoor activity.
Seasonal planning
2h 18m annual swing
June average 13h 16m; December average 11h. This is the year-scale gap to check before travel or outdoor scheduling.
Travel comparison
10 retained peer curves
Mumbai's closest daylight-pattern peers here include Mexico City (2h 21m annual swing), Hong Kong (2h 44m annual swing), Bangkok (1h 37m annual swing), Dubai (3h 8m 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, Asia/Kolkata 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 Asia/Kolkata can still have different daylight and twilight curves because the coordinate pair, especially latitude, drives the result.

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.

What the Mumbai 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
Mumbai, India is modeled at 19.08°N, 72.88°E in Asia/Kolkata. That coordinate pair drives every bar in the 2026 daylight curve.
Seasonal swing
The longest day is Jun 17 at 13h 17m; the shortest is Dec 14 at 10h 59m. The yearly range is 2h 18m, which makes this a low-variation tropical daylight profile.
Latitude context
Mumbai sits in the Northern Hemisphere tropical 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 11h 6m, Mar 15 12h 1m, Jun 15 13h 16m, and Sep 15 12h 15m. These anchors help readers see the shape of the year without reading all 365 bars one by one.
Today and twilight
Today in Mumbai, sunrise is about 6:40 AM, sunset about 6:03 PM, solar noon 12:22 PM, and daylight totals 11h 23m. Civil twilight runs 6:18 AM to 6:25 PM; golden hour windows are 6:26 AM to 7:11 AM and 5:32 PM to 6:17 PM.
Golden hour planning
Today's combined morning + evening golden hour totals 1h 29m. The longest combined golden hour day of 2026 is Dec 21 — 1h 34m. The shortest non-zero day is Mar 21 — 1h 25m. Year-round average is 1h 29m per day across days where a golden-hour window exists.
Twilight ladder
Nautical twilight today: 5:51 AM to 6:52 PM. Astronomical twilight today: 5:25 AM to 7:18 PM. The single longest stretch of true astronomical darkness in 2026 occurs on Dec 21 — 10h 25m. 365 days in 2026 include at least some astronomical darkness.
Seasonal momentum
Fastest daily daylight gain: Mar 4 (+2m from the previous day). Fastest daily daylight loss: Sep 10 (-2m from the previous day). Closest 12-hour balance: Mar 14 at 12h (no change from 12h). Average-month anchors: June average 13h 16m is brightest, while December average 11h is shortest. 0 days reach 14h+ daylight; 0 days stay at 10h or less.
Blue and civil light
Today's combined blue hour totals 18m. The longest combined blue-hour day is Jun 21 — 19m. Blue-hour average is 18m per usable day. The longest civil-twilight-only day is Jun 21 — 49m. Civil twilight averages 46m 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.

- No. Mumbai's latitude produces a full civil/nautical/astronomical twilight ladder on every day of 2026.
Comparable daylight curves
These are selected by latitude and annual daylight swing, not by the generic city list, so the comparison is tied to Mumbai's actual solar profile.
