Task Duration Calculator
Calculate how long a task takes from start to finish. Enter the start date and time, then enter the end date and time to see the total duration in days, hours, and minutes.
Use 24-hour time if your browser displays it that way. For example, 14:30 means 2:30 PM.
Enter the time the task ends.
How This Tool Works
The Task Duration Calculator compares the start date and time with the end date and time. It then converts the difference into total days, hours, and minutes so you can quickly see how long a task or project activity took.
