Attempting to understand time has long been a prime occupation for philosophers and scientists. There are widely divergent views about its meaning, hence it is difficult to provide an uncontroversial and clear definition of time except its physical definition, which dictionaries give as "a non-spatial linear continuum wherein events occur in an apparently irreversible order." This article looks at some of the main philosophical and scientific issues relating to time.

The measurement of time has also occupied scientists and technologists, and was a prime motivation in astronomy. Time is also a matter of significant social importance, having economic value ("time is money") as well as personal value due to an awareness of the limited time in each day and in our lives. Time has long been an important theme for writers, artists and philosophers. Units of time have been agreed upon to quantify the duration of events and the intervals between them. Regularly recurring events and objects with apparently periodic motion have long served as standards for units of time - such as the apparent motion of the sun across the sky, the phases of the moon, the swing of a pendulum.
