Everyday life, daily life or routine life comprises the ways in which people typically act, think, and feel on a daily basis. Everyday life may be described as mundane, routine, natural, habitual, or normal.

Human diurnality means most people sleep at least part of the night and are active in daytime. Most eat two or three meals in a day. Working time (apart from shift work) mostly involves a daily schedule, beginning in the morning. This produces the daily rush hours experienced by many millions, and the drive time focused on by radio broadcasters. Evening is often leisure time. Bathing every day is a custom for many.

Beyond these broad similarities, lifestyles vary and different people spend their days differently. For example, nomadic life differs from sedentism, and among the sedentary, urban people live differently from rural folk. Differences in the lives of the rich and the poor, or between laborers and intellectuals, may go beyond their working hours. Children and adults also vary in what they do each day.

Everyday life is a key concept in cultural studies and is a specialized subject in the field of sociology. Some argue that, motivated by capitalism and industrialism's degrading effects on human existence and perception, writers and artists of the 19th century turned more towards self-reflection and the portrayal of everyday life represented in their writings and art to a noticeably greater degree than in past works, for example Renaissance literature's interest in hagiography and politics. Other theorists dispute this argument based on a long history of writings about daily life which can be seen in works from Ancient Greece, medieval Christianity and the Age of Enlightenment.

In the study of everyday life, gender has been an important factor in its conceptions. Some theorists regard women as the quintessential representatives and victims of everyday life.

The connotation of everyday life is often negative, and is distinctively separated from exceptional moments by its lack of distinction and differentiation. Ultimately this is defined as the essential, taken-for-granted continuum of mundane activity that outlines forays into more esoteric experiences. It is the non-negotiable reality that exists amongst all social groupings without discrimination and is an unavoidable basis for which all human endeavor exists.

Much of everyday life is automatic in that it is driven by current environmental features as mediated by automatic cognitive processing of those features, and without any mediation by conscious choice, according to social psychologist John A. Bargh. Daily life is also studied by sociologists to investigate how it is organised and given meaning. A sociological journal called the Journal of Mundane Behavior, published from 2000 to 2004, studied these everyday actions.

Daily entertainment once consisted mainly of telling stories in the evening. This custom developed into the theatre of ancient Greece and other professional entertainments. Reading later became less a mysterious specialty of scholars, and more a common pleasure for people who could afford books. During the 20th century mass media became prevalent in rich countries, creating among other things a daily prime time to consume fiction and other professionally produced works.
