Calculate the Duration Between Two Times
Our Time Duration Calculator makes it easy to find the exact time elapsed between a start time and an end time, perfect for logging hours, tracking tasks, or planning schedules.
What is a Time Duration Calculator?
A Time Duration Calculator is a tool designed to compute the amount of time that has passed between a start time and an end time. It is useful for a wide range of applications, from calculating the total hours worked on a timesheet to figuring out the length of an event or the duration of a flight. It simplifies time math by handling the complexities of hours, minutes, and seconds.
How It Works: Calculating the Difference
The calculator subtracts the start time from the end time to find the total duration. If the end time is on the next day, it correctly adds 24 hours to the calculation to ensure an accurate result.
Frequently Asked Questions
How do you calculate time duration?
To calculate the duration between two times, you convert both times into a common unit, such as seconds, subtract the start time from the end time, and then convert the result back into hours, minutes, and seconds. Our calculator can do this automatically.
How do you add hours and minutes?
To add time, you add the minutes and seconds separately. If the seconds total is 60 or more, you carry over the extra minutes. If the minutes total is 60 or more, you carry over the extra hours. The Time Calculator handles this automatically for complex additions and subtractions.
How many hours is 9am to 5pm?
From 9:00 AM to 5:00 PM is exactly 8 hours.
