But as I indicated, the intent is to identify the last day of the month - the
intent is not to add a year. The rest of the cells did not add a year making
all the other cells with the desired results as opposed to this one example
from January.

Hi,
If your data is exactly the same as posted your formula added a year because
in column H you have 1/31/10 and in column J 1/31/11 just a year so formula
works

In cells H15 and H36 I have 10/31/09 and 1/31/10 respectively.
In J 15 and J36 I have the following formula:

=DATE(YEAR(H15),MONTH(H15-DAY(H15))+2,)
Cell J36 has With H36 instead of H15.
The intent is to identify the last date of the month identified in column H.

However, the results a
H J
10/31/09 10/31/09 (This worked)
1/31/10 1/31/11 (This added a whole year)

The equation seems to work every where unless the date in column H is in
January.

Column L does something similar to calculate the end of the subsequent
month. It works in all cases. The formula I used for that is:
=DATE(YEAR(H36),MONTH(H36-DAY(H36)+2)+2,)

Why isn't the first formula working in every case?
