    Rounding military times without colons to the nearest quarter hour

    Hello everybody!

    B2=0700 (start time)
    C2=1530 (end time)

    The formula I'm currently using is a simple (C2-B2)/100 function, but of course this yields "8.3" instead of "8.5"

    Is there any way to convert my time input (interval of 15 minutes each) to the amount of hours worked (interval of 0.25 each)?

    Try it like this:

    =CEILING(C2-B2)/100,0.25)

    Hope this helps.

    Yes, there is a way (likely multiple ways) to solve a problem like this.

    I would be inclined to use the DOLLARDE() and DOLLARFR() functions to convert your hhmm values to decimal hours, round to the nearest 0.25 hours, then, if needed, convert back to hhmm.

    1) Divide by 100 to get hh.mm values
    2) Use DOLLARDE(hh.mm,60) to get decimal hour
    3) Round to the nearest quarter hour using MROUND(DOLLARDE(...),0.25)
    4) Use DOLLARFR(MROUND(...),60) to convert rounded value back to hh.mm
    5) Muliply result by 100 to hhmm value.

    Others may have other suggestions.
