Excel stores dates and times as regular numbers and then formats them according to your directions. This might sound confusing, but it makes working with Dates and Times simpler, particularly when you are doing calculations In Windows Excel the date is held as number of days since 1st January 1900 (with time held as a fraction of a day). You only see it as a date if it's formatted that way, either by a Format Cells or by Excel recognizing you've typed in a date and defaulting to date format What you're seeing in the Result row is the time in B4 expressed as a fraction of 1 day. For example, if you multiply the value in B4 by 24, you'll get 17.95, i.e. 17.95 hours out of a total of 24. Formatting the Date Result In many scenarios, you'll want to format the result of your TIMEVALUE formula so it displays as an actual time Excel stores times using the exact same serial numbering format as with dates. Days start at midnight (12:00am or 0:00 hours).

Dates are a count of the number of days from 1 Jan 1900 (or 1904) and times are the decimal fraction. In this article I would like to look at times and the resolution we are able to achieve in our calculations and display formats
And this returns the number of minutes elapsed. =MINUTE (MOD (B14-A14,1)) Then the result is returned as 50. A formula for Elapsed Time in Days, Hours and Minutes. Finally, we need to put this all together as one Excel formula.
