Understanding Sunset in Los Angeles
The term "getting dark" most commonly refers to the time of sunset, which marks the moment the sun disappears below the horizon. For Los Angeles, California, on December 21, 2024, the sun is observed to set at 4:49 PM. This time reflects the transition from daylight to evening, particularly noticeable as December marks the winter solstice period, bringing the shortest daylight hours of the year.
Here are the key times for Los Angeles on December 21, 2024:
| Event | Time | Direction |
|---|---|---|
| Sunrise | 6:55 AM | Southeast (118°) |
| Sunset | 4:49 PM | Southwest (242°) |
After sunset, the sky gradually darkens as the sun continues its path below the horizon. The direction of the sunset, 242° Southwest, indicates where in the sky the sun can be observed descending.
The Gradual Process of Darkness
While 4:49 PM marks the sunset, the sky doesn't become completely dark instantly. Instead, a period known as twilight follows. There are three stages of twilight:
- Civil Twilight: The period immediately after sunset when there's still enough light for outdoor activities without artificial illumination. This lasts until the sun is 6 degrees below the horizon.
- Nautical Twilight: During this phase, the horizon is no longer visible, but major stars and planets are. This is when the sky becomes significantly darker, and lasts until the sun is 12 degrees below the horizon.
- Astronomical Twilight: This is when the sky is truly dark, and the faintest celestial objects can be seen, as the sun is 18 degrees or more below the horizon. This is considered full night.
Therefore, while sunset at 4:49 PM is when the process of getting dark begins, full darkness sets in later, after astronomical twilight has ended.
Factors Affecting Darkness
Several elements can influence exactly when it feels "dark" in a specific location:
- Time of Year: Daylight hours fluctuate significantly throughout the year. Winter months, especially around the December solstice, have the earliest sunsets and longest nights.
- Weather Conditions: Cloud cover, fog, or heavy precipitation can make it appear darker earlier in the day than clear skies would.
- Local Topography: Mountains or tall buildings can block the sun's rays earlier than the official sunset time for a specific location.
