consecutive bi-monthly dates

[dmr]

Is there a way to consecutively add bi-monthly dates to a spreadsheet? Kind
of different because the 15th will always be 15. It's the last day of the
month that changes each month. This would be for people who are paid
bi-monthly so the dates don't have to be input each time.

If you've got 15 Sep 07 in A1, then in A2 put =DATE(YEAR(A1),MONTH(A1)+1,0)
which will give the last day of the month.
In A3 put =DATE(YEAR(A1),MONTH(A1)+1,DAY(A1)) to give 15th of the next
month.
Select A2 and A3, and fill down.

Enter this in A1 & fill down to A24:
=IF(MOD(ROW(),2)=1,DATE(2007,(ROW()+1)/2,15),DATE(2007,ROW()/2+1,0))

You can use the DATE function. Inputting a 0 for the day, will result in the
last day of the previous month.

So, for example, your starting data is in A1. In A2 enter:

=IF(DAY(A1)=15,DATE(YEAR(A1),MONTH(A1)+1,0),DATE(YEAR(A1),MONTH(A1)+1,15))

One way:

Enter the first date in cell A1. Either the 15th or the last date of that
month. Like this:

A1 = either 1/15/2007 or 1/31/2007

Enter this formula in A2 and copy down as needed:

=IF(DAY(A1)=15,DATE(YEAR(A1),MONTH(A1)+1,0),A1+15)
