Can anyone advise how can I find if the given date in a cell belongs to the current month or previous month or next month of the year.

For Example 

```
 A               B (result I want to achieve...)       
 05/12/2014      Last month     
 06/12/2014      Current month    
 07/17/2014      Next month
 06/14/2012      Past date    

```
