    How do I round time to the nearest quarter of an hour

    I am not too understanding of excel to any great extent. But I need to round
    time to the nearest quarter.

    Example

    8:11 to 8.25
    4:41 to 4.75

    I am assuming from you example that you are rounding up the time.

    Here are the two solutions:

    =CEILING(A1, TIME(0,15,0))*24

    =TIME(HOUR(A1),CEILING(MINUTE(A1),15),0)*24
    Google is your best friend!

    If you want the answer in decimal hours use this formula and format the cell
    as a number
    =ROUND(A1*24*4,0)/4

    If you want the answer in Excel time use this formula and format the cell as
    time
    =ROUND(A1*24*4,0)/24/4

    These round to the nearest quarter hour so 4:17 will yield 4.25 or 4:15

    Not used Ceiling() before, why won't it accept negative numbers.

    It is meant to round up to - no mention of only working with >=3D0 numbe=
    rs

    -- =
