The hours calculator calculates the total number of hours and minutes between the start and end times.

To use the calculator, follow the steps below:

- Firstly, input the start and end times and select the 'AM' or 'PM'. The tool supports a 12-hour time format. So, ensure the hours are between 0-12 and the minutes between 0-60.
- After entering the time, press the 'Calculate' button to generate the final results.
- As a result, the tool returns the hours and minutes and the total minutes.
- Press the 'Reset' option for the new calculations.

Let's understand it with an example.

Find out the hours and minutes between the following times:

**Start time = 10:05 AM****End time = 12:30 PM**

First, subtract the start time hours from the end time hours.

**12 - 10 = 2**

Similarly, subtract the start time minutes from the end time minutes.

**30 - 5 = 25**

Now combine both results.

So, the duration between start and end times is **2 Hours 25 Minutes**.

1 Hour = 60 Minutes

Total Minutes = **60 + 60 + 25 = 145**.
