+2 date formula adds 2 days to blank cells

I wrote a quick import formula (=A2)+2 to pull in the date from A2 and add 2 days. If there is a date present it works fine. If A2 happens to be empty or blank it returns 1/2. Apparently if a cell is blank and formatted for dates (mm/dd) it has a value of 1/0 because something like 4/6 will return 4/8. How can I keep this from happening? Both columns are formatted for dates, and I have special formatting on worksheet to replace all zeros in cells with blank cell.

A/2: blank
S/2: =(A2)+2
A format for dates
S format for dates
worksheet formatted to show blank cells for zero cells
S2: populates 1/2

A3: "4/7" (april seven)
S3: =(A2)+2
A format for dates
S format for dates
worksheet formatted to show blank cells for zero cells
S2: populates "4/9"

I want S2 to populate nothing. Can I use IF or SUMIF?

Any help is greatly appreciated

That formula I had figured out. The problem is that it returns 1/2...the same thing as a simple grab. What I need is a formula that grabs the date from B2 only if there is a date there and returns nothing if B2 is blank (A2 in your formula is B2 to me).

Unless I do not know how to use it, no. Here is my book. click on teh dawn tab and drop yoru formula into P2 then drag it down. You will see every date will have 2 days added to it, but the blank cells will return 1/2. I think it has something to do with number formating...I had a dilly of a time today with that trying to make it so the nurses could enter 2245 and have it return 22:45. I know that is time and has nothing to do with date, but I swear it never did this before.

Thank you!
