When afternoon changes into evening, there is no defined time on the clock because it is determined by the position of the sun in the sky. As a result, the difference between afternoon and evening varies depending on the season; the sun sets later in the spring and summer, therefore evening begins and ends later. In general, the afternoon is the time of day when the sun begins to set after reaching its highest point in the sky at noon. Evening usually begins when the sun is low in the sky and finishes when the sun has set and twilight has passed.
In the United States, an afternoon is defined as the period between midday and 5 p.m. or 6 p.m., while an evening is defined as the period after those periods until the sky is totally dark at night. There is no established timing for the change between afternoon and evening, and lifestyle and culture can also influence what some people consider afternoon or evening. This shift is frequently determined by the time of day when business hours are typically over, which varies by country.
According to Dictionary.com, an afternoon is “the period from midday to nightfall,” and an evening is “the period between the end of the day and the beginning of the night.” The normal workday in the United States concludes at 5 p.m. Even if the position of the sun in the sky does not seem as it does when we conventionally think of evening, such as during summer when it is still bright out, this is the generally acknowledged hour for the beginning of evening for scheduling purposes.
The time on the clock might also have an impact in other ways. Tea hours in England are commonly used to distinguish between afternoon and evening. Afternoon tea is a customary snack served at 4 p.m. Even in the winter, when locations may already be experiencing light conditions that resemble nightfall, afternoon tea is still considered.
