    Overlapping Time Intervals of the Same Date

    Hello,

    I'm trying to determine if there are any overlapping time intervals within one day.

    The data looks like this:

    12/8/2014 11:30:00 AM 12:00:00 PM
    12/8/2014 11:45:00 AM 12:30:00 PM <-- Overlaps the time interval in the record above it.
    12/8/2014 6:00:00 PM 8:00:00 PM

    I would like the column to the right of these two columns to inform me that "YES" somewhere in these two columns, within the same day, an overlapping of time exists.


    Any help would be appreciated!

    Thanks,
    Channing

    "I would like the column to the right of these two columns"

    You don't say where the 2nd column begins.
    What's in the first and second columns

    Ensure you describe your problem clearly, I have little time available to solve these problems and do not appreciate numerous changes to them.

    Re: Overlapping Time Intervals of the Same Date

    I can see how that would make things confusing. The columns are as follows --

    A1
    12/8/2014

    B1
    11:30:00 AM

    C1
    12:00:00 PM



    Thanks!

    Re: Overlapping Time Intervals of the Same Date

    If the times are sorted by start time in each day then presumably there is only an overlap if the end time from one row is later than the start time for the next row.....and both are the same date, so in formula terms try this formula in D2 copied down

    =IF(AND(A1=A2,C1>B2),"Yes","")
    Audere est facere
