Twilight type reference
| Type | Sun angle | Description |
|---|---|---|
| Golden hour | 0° – +6° | Warm diffuse light — ideal for photography |
| Civil twilight | 0° – −6° | Bright enough for outdoor activities without artificial light |
| Nautical twilight | −6° – −12° | Horizon still visible for marine navigation |
| Astronomical twilight | −12° – −18° | Dark enough for most astronomical observation |
Frequently asked questions
How accurate is this sunrise/sunset calculator?
The calculator uses the NOAA solar algorithm, which is accurate to within about 1 minute for locations between ±65° latitude. Accuracy decreases near the poles due to atmospheric refraction effects.
What is golden hour?
Golden hour is the period shortly after sunrise and before sunset when the sun is low in the sky, producing warm, soft, directional light. Photographers prize this time because shadows are long and the light is flattering. It begins at sunrise and ends when the sun reaches 6° elevation in the morning — and reverses in the evening.
What is the difference between civil, nautical, and astronomical twilight?
Civil twilight (sun 0°–6° below horizon) is bright enough for outdoor activities. Nautical twilight (6°–12°) allows marine navigation by the visible horizon. Astronomical twilight (12°–18°) is dark enough for most stargazing. Below 18° is true night.
