Formula, Blank Cell

Sorry in advance if this has been asked but I can't see anything. Excel 2010

I have a cell that will contain a date then the next adjacent cell the same date plus 1 year then the next adjacent will highlight the year plus 1 minus two weeks (like an expiry warning). I started well with the date and date plus 1 but tried to add in if blank function i.e. if no date appears in first cell then second cell should be blank.

C2 is the date cell D2 is the date plus 1 and E2 is the same as D2 minus 14 days.

This is as far as I got for the formula in D2 =IF(C2="","",C2=DATE(YEAR(C2)+1,MONTH(C2),DAY(C2)))
This works with the blank C2 but when a date is entered D2 changes from blank to FALSE and I'm too much of a beginner to figure out why.

Thanks in advance,

Andy
