Answer:
This simple online tool makes it easy to calculate the difference in hours and minutes between two given times. To calculate the hours and minutes contained in a time period you need to know its beginning and end. The hours calculator will use the time format depending on your browser locale settings, e.g. US, UK.
After you enter the beginning and the end of the time period you are interested in, you simply click the "Calculate difference" button. Below you will get the difference in both full hours and in minutes. If the first hour you enter is later in the day than the second hour you enter, the time difference is calculated as if the first hour is for today and the second is tomorrow. For example, entering a start time of 6PM and end time of 8AM in the calculator, it will calcualte the difference in hours, minutes, and seconds from 6PM today to 8AM tomorrow (14 hours).
This calculator for the number of hours between two times could be used to find out for how long you have worked in order to fill in time sheets. For example, how many hours are there between 9 and 5:30 pm (or 9:00 and 17:30)? You simply need to enter the two times in any order and click on "Calculate". The result will be 8 hours 30 minutes (8:30 hours or 8.5 hours in decimal) or 510 minutes. There are 8 full hours between these times.
