Afternoon denotes the part of the day that follows noon and precedes evening. Commonly, the afternoon is considered to begin at 12:00 pm (noon). Its end is not fixed and may be defined by convention, daylight levels, social customs or the approach of evening activities.

Typical bounds and daily role

In everyday usage the afternoon often covers the hours from about 12:00 pm until roughly 4:00 pm to 6:00 pm. This range varies with culture, season and latitude: at higher latitudes in summer the period of daylight that feels like afternoon can extend late into the evening, while in winter it may be much shorter. The afternoon is commonly the span when many workplaces and schools remain active, appointments are scheduled and errands are run.

History and language

The English word combines "after" and "noon." Historically the meaning of "noon" itself shifted over centuries: medieval and religious timekeeping once placed the canonical noon hour later in the day than the modern 12:00 pm. Standardization of clocks and civil timekeeping gradually fixed midday at twelve o'clock, shaping the modern sense of the afternoon.

Cultural practices

  • Meals and breaks: many cultures have a lighter meal or snack in midafternoon; some observe a siesta or rest period in the early afternoon.
  • Social rituals: traditions such as afternoon tea grew from social and practical rhythms tied to this part of the day.
  • Work rhythms: businesses and schools commonly schedule meetings, classes and activities through the afternoon hours.

Physiology and practical notes

People often report a decline in alertness in the early to mid-afternoon, linked to normal circadian rhythms and the effects of recent meals. Short breaks, light activity, hydration or brief naps are commonly used to counteract the post-lunch dip. Seasonal changes, daylight saving adjustments and local climate can all influence how the afternoon is experienced and organized.

Other uses and imagery

Afternoon is also used figuratively to describe a later phase of life or a period of waning activity in narratives and common speech. In art, literature and everyday description, the distinctive light and atmosphere of the afternoon—longer shadows, warmer tones and changing sky—make it a frequent setting for scenes and observations.
