What is the Difference Between Dusk and Dawn?
🆚 Go to Comparative Table 🆚Dusk and dawn refer to different periods of the day, and they are related to the Sun's position in relation to the horizon. Here are the main differences between the two:
- Dusk: This occurs in the evening hours when the Sun sets over the horizon, and the skies gradually darken. Dusk is marked by the Sun's center being at an exact point below the horizon, and it is divided into three types based on the Sun's distance from the horizon:
- Civil dusk: Sun's center is 6° below the horizon
- Nautical dusk: Sun's center is 12° below the horizon
- Astronomical dusk: Sun's center is 18° below the horizon
- Dawn: This occurs in the morning when the Sun rises, and it gets light. Dawn is also marked by the Sun's center being at an exact point below the horizon, but it represents the beginning of the day rather than the end.
Twilight is another term often associated with dusk and dawn, but it is different from both. Twilight occurs between the points when the Sun's center is at the exact point below the horizon, and it is the period after sunset or before sunrise when the sky is illuminated by reflected sunlight.
