During which stage of development do children start to understand the concept of time?

In the school-age stage of development, typically around ages 6 to 12, children begin to grasp the concept of time more concretely. During this period, they develop the ability to understand sequences of events and how time is measured in hours, days, and months. This understanding evolves from the earlier stages, where children might have a more abstract sense of time tied to daily routines or immediate experiences but lack a comprehensive understanding of past, present, and future.

As children interact with schedules, school routines, and structured activities, they learn to relate their actions and experiences to the passage of time, recognizing patterns such as days of the week or seasons. This cognitive development is crucial, as it lays the foundation for more complex concepts of time management and planning in later stages of adolescence and adulthood.
