Excel 2005: Difference between two days, counting hour difference



I've been trying to get this Excel function working correctly, and I've hit a wall. I'm trying to calculate the exact difference in days between two dates, taking the start time into account as well as the start day. Seems like this should be a common need?


Example:


Start Date End Date Expected Result
9/20/2010 8:00am 9/22/2010 3:00pm 2.3 days

I'm guessing at the .3, but you get the idea :)
My current formula looks like this:


=IF(End < NOW(), 0, IF(Start >= NOW(), End-Start+1, End-NOW()))

It works

Thanks.

How can I calculate the difference in days between two days stored as YYYYMMDD in a query?
Programming Languages

I am writing a query where I need to calculate the number of days since a date that is stored in the database in the format "YYYYMMDD". Since this is not a Date datatype, I can't use native Date functions. What is the best way (performance-wise, readability-wise, etc.) to perform such a calculation in a SQL query.

Grub2: confusing difference in partition counting and device counting
Programming Languages
In Karmic, Grub2 will be installed. The successor to the current Grub.
Grub2 still has a nasty bug. Partition counting starts at 1. However, device counting starts at 0 (the old method). This difference is very unwise and will cause needless confusion.
Counting of partitions and devices should be exactly the same. Both of them should start counting at 1, or both of them should start counting at 0 (old method). No mix.
I've filed a Launchpad bug report:

Please feel free to support it there. Maybe there is still time to change this before Karmic arrives. :)
Time Difference Split in hour intervals excel vba
Programming Languages

This one is a thinker!

I have the below data set:

Data

My goal is to get the time difference and split it into hour intervals. i.e. how much time was spent by each person in each hour as below:

Table

So the end result should look like this: Result

Covering the fist scenario is pretty easy:

Private Sub CommandButton21_Click()

LastRow = Worksheets("Sheet1").Cells(Worksheets("Sheet1").Rows.Count,
"A").End(xlUp).Row

For MyRow = 2 To LastRow

If Format(Worksheets("Sheet1").Range("B" & MyRow).Value, "hh") =
Format(Worksheets("Sheet1").Range("C" & MyRow).Value, "hh") Then

    Set oLookin = Worksheets("Sheet2").UsedRange
    sLookFor = Worksheets("Sheet1").Range("A" & MyRow)
    Set oFound = oLookin.Find(What:=sLookFor, LookIn:=xlValues,
LookAt:=xlPart, MatchCase:=False)

    If Not oFound Is Nothing Then
        Worksheets("Sheet2").Cells(oFound.Row,
(Format(Worksheets("Sheet1").Range("B" & MyRow).Value, "hh")) +
1).Value = _
        Worksheets("Sheet1").Range("C" & MyRow).Value -
Worksheets("Sheet1").Range("B" & MyRow).Value
    End If
End If

Next MyRow

End Sub

However covering the second the third scenarios is where I am find it challenging. How do I go about if the "Time In" hour is not the same as "Time Out". And then how do I split the hours and stop at 00:00:00 as subtracting 00:10:00 from 17:00:09 will give you #############.

I have been trying to figure out a solution, even thought of using a class module somehow? But haven't been able to figure it out :(

Help and suggestions are highly appreciated.
