Evening

physical science Maturity 7-9 Next article →

Evening is a specific period of the day. It begins at the conclusion of the afternoon. This time period overlaps with both twilight and the start of night. The sun remains close to the horizon during this phase.

Because the sun's position changes, the timing is subjective. It depends on your location and the time of year. Some people define the start of evening as occurring during daylight. This means it can begin before the actual sunset occurs.

The word "evening" has a long history in the English language. It is derived from the Old English word æfnung. This term meant the coming of evening or the time around sunset. It also comes from the verb æfnian. This verb meant to grow toward the evening or to become evening. Another related Old English word was æfen, which is often called "eve." This word meant the time between sunset and darkness. It was synonymous with the word even. People have used the term "evening" since the mid-15th century.

Defining the exact hours of evening can be difficult. Many people consider the evening to begin at 5 p.m. The Oxford English Dictionary provides a different social definition. It states that evening starts at 6 p.m. or at sunset, whichever happens earlier. The end of the evening is also not a fixed time. It can end around 9 p.m. depending on the context. For many individuals, the evening ends when they go to bed.

Astronomers find the evening useful for specific types of observation. The lighting conditions are not ideal for all optical astronomy. However, the evening is an optimal time for viewing certain celestial bodies. These are objects that orbit close to the Sun. The inferior planets, Venus and Mercury, are best seen during the evening or the morning.

This period is also a popular time to hunt for comets. Comet tails become more prominent as the objects draw closer to the Sun.

Twilight provides further opportunities for scientific discovery in space. Scientists use evening and morning twilight to search for near-Earth asteroids. These are asteroids that orbit inside the orbit of the Earth. In mid-latitudes, certain spring evenings are especially favorable for observation. This occurs around the time of the equinox. The equinox is a time when the sun is directly above the equator. In the Northern Hemisphere, this happens in March. In the south of the equator, it happens in September. During these times, observers may see the zodiacal light.

Biology also connects to the timing of the evening. Some animals are specifically adapted to this time of day. These are known as crepuscular animals. Crepuscular animals are those that are active primarily during the early morning and the evening. This behavior allows them to utilize the specific light levels of twilight. The transition from day to night creates a unique environment for these living things.

Understanding the evening helps us connect different fields of study. It links the movement of the sun to human social habits. It also connects the rotation of the Earth to the study of space. Whether we are looking at the history of language or the orbit of a planet, the evening is a vital transition. It serves as a bridge between the light of the day and the darkness of the night.
