Elapsed Time Clocks

Use the two clocks to compare a start time with an end time. Drag the hour and minute hands to set each time and see exactly how much time has passed.

The digital displays update automatically as the clock hands move. Students can practice reading AM and PM, switch between 12-hour and 24-hour time, and link the clock faces so they move together.

How to Use

• Drag the hands on the left clock to set the start time.
• Drag the hands on the right clock to set the end time.
• Read the elapsed time displayed below.
• Select Link to move both clock faces together.
• Select 12 or 24 to change the digital time format.
• Select Hide to conceal the elapsed-time answer.
• Use the colored circles to change each outer ring.

Use this interactive clock activity to teach elapsed time, compare start and end times, calculate duration, and explore time intervals.
