Use array/braces **WITHIN** a formula?

[wal]

Excel 2003

I'm trying to set up a formula that gives the date range for the first
week (or partial week) of the month. If the first day of the month is
a Sunday, then the result would read "September 1-7"; if the first day
is a Monday, then the result would read "September 1-6"; and so on.

The hard way is a formula like this:

=IF(WEEKDAY(C3)=1,TEXT(C3,"mmmm d") & "-" &
TEXT(C3+6,"d"),IF(WEEKDAY(C3)=2,TEXT(C3,"mmmm d") & "–" &
TEXT(C3+5,"d")))... [and so on]

This gets cumbersome, matching up all the parentheses.

Can this be abbreviated with an array-type formula? I was hoping the
following would work, but it doesn't:

=IF(WEEKDAY(C3)={1,2,3,4,5,6,7},TEXT(C3,"mmmm d") & "–" &
TEXT(C3+{6,5,4,3,2,1,0},"d"))

I typed the braces myself, which is incorrect. You have to enter
array formulas (including the braces) with control-shift-enter, but
that only works if the whole formula is an array formula, right?

Anyway, is there any way to abbreviate what I'm trying to do? Thanks.

=TEXT($C$3,"mmmm d") & "-" &TEXT(8-WEEKDAY($C$3),"d")

The date in C3 must be the 1st day of a month... 09/01/2011

You have a couple of solutions to the abbreviating your formula.

I would just like to clarify your thoughts about curly braces inside
formulas.

Yes, you can use them to create arrays within a formula.

=LOOKUP(B1,{1,2,3,4},{"A","B","C","D"}))

which saves having to create a lookup table range on sheet.

=SUM((LEN(A1)-LEN(SUBSTITUTE(A1,{1,2,3,4,5,6,7,8,9},"")))*{1,2,3,4,5,6,7,8,9})

Sums only numbers within a string like 1234abcd4321

Thanks to all for the solutions.

(I think with Ron's, the "8" needs to be a "7", assuming a Sun.-Sat.
week.)
