The Hours Calculator allows you to perform basic arithmetic operations (addition and subtraction) with time. Simply enter the hours and minutes for two time intervals, select the operation you want to perform, and click the "Calculate" button to see the result.
For example, if you want to add two times, enter the hours and minutes for both time intervals in the respective input fields, select the "Add" operation, and click "Calculate" to see the sum of the times.
Keep in mind that time should be entered in the form of hours and minutes, and both should be integers.
