You would do this using conditional formatting. Let's say you want to have
the cell highlighted if the date is <= today.

Select the cells
Format - Conditional formatting
Formula is: (select the first cell) and then enter <= today()

You should see something like

=$A$1<=today()

You will probably want to remove the $ from the formula if it applies to
multiple cells.

This is the formula that I have in the column:
=IF(K104=0,"",(DATE(YEAR(K104),MONTH(K104)+24,DAY( K104))))

If the month and year is reached I want the cell highlighted in red, if
exceeded I want the cell in yellow.

How do I do this?
