How Sunrise & Sunset Times Are Calculated
This tool uses the NOAA solar position algorithm (based on astronomical equations) to compute the Sun's position for any latitude, longitude and date. It calculates when the Sun's upper limb reaches −0.833° (sunrise/sunset standard refraction), −6° (civil twilight), and ±1° above the horizon (golden hour).
Solar Events Reference
| Event | Sun Angle | Description |
|---|---|---|
| Astronomical Dawn/Dusk | −18° | First/last hint of light |
| Nautical Dawn/Dusk | −12° | Horizon visible at sea |
| Civil Dawn/Dusk | −6° | Enough light for outdoor work |
| Sunrise/Sunset | −0.833° | Upper limb of Sun at horizon |
| Golden Hour | 0° – 6° | Warm, soft photography light |
| Solar Noon | Max altitude | Sun at highest point |
Polar Regions
At high latitudes, the Sun may not rise at all (polar night) or may not set (midnight sun). In these cases the tool will display a message rather than times.
