Time is a central concept in metaphysics concerned with how events are ordered, how duration is understood, and how change occurs across past, present, and future. Metaphysical inquiry asks whether time exists independently of events, whether it is a feature of reality or a framework used to organize experience, and whether the passage of time is objectively real. Questions about time connect closely with space, causation, change, identity, persistence, possibility, and determinism, making it one of the fundamental structures through which reality is examined.
