The device for teaching the concept of elapsed time is an educational tool for teaching children the concept elapsed time, and how to understand the passage of time, with emphasis on particular time intervals, such as hourly intervals or portions of the day, and activities associated therewith. The device includes an elongated strip having longitudinally opposed first and second ends. The elongated strip further has opposed front and rear surfaces, and a first set of graduated demarcations is formed on the front surface. A first set of indicia are formed on the front surface adjacent the first set of graduated demarcations, with the first set of demarcations and the first set of indicia representing hours of the day. The first set of indicia represents the hours in the form of "1:00 P.M." or "12:00 A.M", for example. The first and second ends are preferably joined together to form a loop.
