Time is a fundamental concept used to describe the sequence of events and the duration between them. It is a continuous and irreversible process that is used to measure the duration and order of events, as well as the interval between them.In physics, time is often considered a fourth dimension, alongside the three dimensions of space. It is measured in units like seconds, minutes, hours, and years, and can be described using terms like past, present, and future.

However, the nature of time is still not fully understood, and different fields of science and philosophy have different interpretations of what time actually is. Some theories suggest that time is an absolute and fundamental property of the universe, while others suggest that it is a subjective experience that arises from the way we perceive and interpret events.

Regardless of its true nature, time is a helpful aspect of our daily lives, shaping our experiences and influencing our understanding of the world around us as it structures how and when we do things.
