Calculation in a Row

K

Is there a calculation (function) that will look in a row and return the
number of continuous dates in number format?

Sample:

Name Date of Absense In A Row
Doe, John 12/17/04 4
Doe, John 12/18/04 4
Doe, John 12/19/04 4
Doe, John 12/20/04 4
Doe, John 12/24/04 1
Doe, John 12/27/04 1

The number in the "In A Row" column should calculate off the "Date of
Absense" column as it looks down the row and sees the date change.

Any suggestion would be helpful.

Thanks!

Hi!

Here's one way but requires a helper column in addition to the column "In a
Row" Also requires an empty row immediately above the data.

Dates in column B. B1 is the header "Date of Absense" Row 2 is empty and the
actual dates are in the range B3:Bn

Helper column will be column C. "In a Row" will be column D.

Enter this formula in C3:

=IF(B3=B2+1,B2+1,1)

Enter this formula in D3:

=IF(B3+1=B4,D4,C3)

Select both C3 and D3 then copy down as needed.

Assuming if someone is off on a Friday and a Monday, you want that to count
as 2 consecutive days.

Try this:
=IF(WORKDAY(B2,-1)=B1,C1+1,1)

(If the WORKDAY function is not available, and returns the #NAME? error,
install and load the Analysis ToolPak add-in.)

Otherwise:
=IF(B2-B1>1,1,C1+1)

Does that help?

Biff,

I did not get the number of days. The calculation returned the date number.
Is there a way to change it from date number to number of days?

Hi!

Ooops!

Slight correction in the first formula:

Should be:

=IF(B3=B2+1,C2+1,1)
