I created an Excel Spreadsheet with a Total Time for the Duration of the Shift ie 8:30-17:30.
Then I created this formula
=(MOD([@[Supposed Shift End]]-[@[Supposed Shift Start]],1))*24
with Format cells -> Number 2 decimal places. This gives me the [Total Supposed Shift Hours]
Giving me Duration of the Shift that needs to be covered.
Now I also created another column for the ACTUAL time the shift covered
=(MOD([@[Actual Time End]]-[@[Actual Time Start]],1))*24
This gives me the [Total Actual Time Hours]
For the Actual Time End and Actual Time Start When the employee DIDN'T show up we entered 0 for both cells with the same cell format Number -> 2 decimal places
The Problem:
This is the formula I wrote to subtract these 2 Columns
=(MOD([@[Total Supposed Shift Hours]]-[@[Total Actual Time Hours]],1))*24
Why when I subtract say the [Total Supposed Shift Hours] 9.00 - the [Total Actual Time Hours] 0.00 = 24.00 ???
9 - 0 = 9 not 24.... sigh
Will the formula be affected if the time goes from previous night 21:00 to 8:00 with the MOD formula?
Sample data (as requested)
Note: Nomenclature differs from description above: Open
= Supposed
and Covered
= Actual
Service Date | Open Post Start | Open Post End | Total Hrs Missing | Covered Post Start | Covered Post End | Total Hrs Covered | Category | Hours Not Covered |
---|---|---|---|---|---|---|---|---|
02/06/2021 | 16:00 | 00:00 | 8 | 16:00 | 03:00 | 11 | A | 0 |
04/06/2021 | 16:00 | 00:00 | 8 | 00:00 | 00:00 | 0 | A | 0 |
10/21/2021 | 10:30 | 00:00 | 13.5 | 18:00 | 19:30 | 1.5 | B | 0 |

Initial Answer
A minor point first: You don't need to wrap the MOD
function in brackets. As the function already produces a result to the *24
. Thus the following works just fine:
=MOD([@[Supposed Time End]]-[@[Supposed Time Start]],1)*24
To your question: Your non-working formula reads as if it simply wants the difference (in hours) between Supposed
and Actual
. If that's so, simply do this:
=[@[Total Supposed Shift Hours]]-[@[Total Actual Shift Hours]]
EDIT: Using the (now posted) table, I've constructed what I think it is you're trying to do
Refer to Sample results image below.
Formula in Colum E: =MOD([@[Open Post End]]-[@[Open Post Start]],1)*24
Formula in Colum H: =MOD([@[Covered Post End]]-[@[Covered Post Start]],1)*24
Formula in Colum J: =[@[Total Hours Missing]]-[@[Total Hours Covered]]
Sample results:
Now: If Column J (i.e. the response to your core question) isn't the result you're after, can you tell me what it is you would expect there (using actual expected values for each row).
Notes:
- Your table column header
Total Hours Missing
is somewhat confusing.
But, I'm reading that aPost Duration
(Duration of Shift
in your original parlance). - If I understand what transpired correctly, the "spanner in the works" was @P.b suggestion to remove
MOD
. Revert your formulas in columnsE
andH
as shown above.
