### Examples of how to calculate time differences?

You need to know the age or want to determine the number of hours a flight will take or how much time it took to finalize a certain task.

#### 1. Calculating how long it will take

Let’s say you have a trip, and you go by flight, bus, train, car, or ferry. You know at what hour the journey starts, and when it will arrive at the destination. To calculate the number of hours between the two dates, add them in the start and end fields, and the calculator does the rest for you. Let’s say it leaves at 7:30 AM and arrives at 1PM. It will be easy to see that the duration will be 5 hours and 30 minutes.

#### 2. Calculating the time duration

When you want to identify the time duration in work hours you used for a specific project, once again use the same calculator. Let’s say you have started at 8:20 and ended at 11:05 for a specific task, then you know you can count 2:45 for that project.

#### 3. How much time until

If you’re interested in calculating a countdown to a specific date and time, once again, this free tool will help with the exact answer. Just by adding today’s date and the date and time when the event takes place, you will have the time and date in front of you.

#### 4. Time elapsed calculator

When you want to count the elapsed time or the time that has passed during an event, let’s say, a chess match, a marathon, a winter, or the completion of a complex project in days, minutes, and hours, once you have identified the start and end times, finding the result will be super easy.
