Is it possible to grab just the Mondays-Thursdays of every month?

I am creating a spreadsheet to keep track of dentist office productivity. In
one box, I want to allow the user to enter the month and have the workdates
change accordingly. For example, our office works Mondays through Thursdays.
In 2005, the first Monday in January is the 3rd. How could I change the
dates to read 3, 4, 5, 6, then skip to 10, 11, 12, 13, then skip until all
the M-Th of the month are included.

These dates should change if the user types in a different month.

Thank you for your help.

The MOD function is often used to take care of this type of issue.
MOD(cell address,7) will produce...
0 for Satuday
1 for Sunday
2 for Monday
3 for Tuesday
4 for Wednesday
5 for Thursday
6 for Friday

if you put the starting date in cell A1, the following formula in cell A2
should work for Monday (2) through Thursday (5).

=IF(OR(MOD(A1,7)<2,MOD(A1,7)=5),A1+CHOOSE(MOD(A1,7)+1,2,1,0,6,5,4,3),A1+1)

In English... If A1 is less than Monday OR A1 is equal to Thursday then Add
enough days the date in A1 to get to the following Monday [this part takes
into account if you, for example, plop a hard-coded date of a Friday,
Saturday or Sunday into the middle of the formulas], otherwise add 1 day to
the date in A1.

Hope this helps,
Sincerely,

Good point about the 'Weekday' function
Change the formula below to read..
=IF(OR(WEEKDAY(A1)<2,WEEKDAY(A1)=5),A1+CHOOSE(WEEKDAY(A1)+1,2,1,0,6,5,4,3),A1+1)
HTH,

If you put some date in the month in A1, then the following formula in A2 will
give the first Monday of that month:

A2: =A1-DAY(A1)+8-WEEKDAY(A1-DAY(A1)+6)

Then in

A3: =A2+1

and copy/drag to A5 giving

A4: =A3+1
A5: =A4+1

Then in

A6: =IF(ISNUMBER(A2),IF(MONTH(A2+7)=MONTH($A$1),A2+7,""),"")

and copy/drag down to A20
