Join Dennis Taylor for an in-depth discussion in this video Rounding time calculations to convenient intervals, part of Excel 2013: Working with Dates and Times.
…In this worksheet called Rounding Time, column A…contains a series of starting dates and times.…In column B, ending dates and times.…We'd like to not only calculate the difference in column…C, but also show how we might, at different times,…need to round those differences to the nearest day or…to the nearest hour or to the nearest 15 minutes.…Let's begin by simply writing a formula here,…equal the ending date, minus the starting date.…A key problem in dealing with math with time, is the formatting,…and nearly always, it seems as if we need to change the format.…
Now if it were simply a question of time, we go…right into by right click format cells or by pressing control one.…Go to the number tab, choose the time category, pick an entry like this.…But if any of these differences are likely to exceed 24 hours…and they certainly will in some of these cases, we need to choose…the format that contains the 37, and since many many times you…do not want to see seconds in the answer, and this does show those.…Let's cut over to Custom, and simply strip off the remaining portions of this format.…
