Copy / Paste range of cells based on number of workdays in a month

[mikemathis]

Hi all,
I have a range of data (A3:J26) that I want to repeat in a single tab. Each set of data would be for each workday of a given month. (I have 12 tabs, so I would do this for each month)

So what I would like a formula to do (please not VBA or macro) is the following:

For the number of workdays in a month,
copy a given range of cells
and paste them below the previous

e.g. February has 20 workdays, that data range would copy 20 times
March has 22 workdays, so that data range would copy 22 times (on a separate tab)

I have played with INDEX and Arrays and I think the answer might include those, but I'm just frustrating myself.

thanks for any help.
