Use this calculator to easily calculate the hour difference between any given two times within a day. It will also show you the result in minutes, if hour calculation is not enough for you.
How to calculate hours between times?
This simple online calculator makes easy calculating 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 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. You could do the calculations starting from the earlier or from the later hour.
This hours calculator 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 full hours; 510 minutes; 8:30 hours; or 8.5 hours in decimal.
American vs. European time
The way Europeans and Americans tell time is different, both in the way it is said and in the way it is written. Civilians in America use the hours until 12 two times in a day, while Europeans go between 00:00 and 23:59. For this reason in America people would use pm and am to distinguish what half of the day they are talking about. On the other hand, most Europeans would probably say 15:00 o’clock (instead of 3 pm). To make it even more complicated for guests from overseas thou, many Europeans would also say 3 in the afternoon.
If you are new to Europe and need to deal with "military time", all you have to do is use the hours until 12 in the same way and for after 1 pm either add or subtract 12, putting pm after the result. For example, if you are meeting someone at 17:30, that would be 17:30 – 12 = 5:30 pm. If you need to find out what to write to a colleague you want to meet at 2pm, this would be 2 + 12 = 14 pm.
For the sake of accuracy, it should be noted that, although similar to it, European time telling is not exactly military time. In the military 18:00 (6 pm) would be 1800. In one case it is "eighteen o’clock", in the other it is "eighteen hundred". In the military 7:00 (7 am) would be "zero seven hundred" or "oh seven hundred" (0700), while civilians in Europe would just say "seven". The stricter military way of communicating time is necessitated by the critical conditions in which it is used. Mistaking the hour or minute of an action could result in lost lives...
