Displaying a Holiday or Monthly Event in a Web Part

I created several custom lists that display a specific Holiday, Pay Dates, Birthday, Etc...
I now want this list to display as a web part and only display the "current month" activities.   After trying a few methods, I stumbled upon this calculated column to solve my issue.

• First I created all the custom columns, including a Date Column (DateDisplay).  
• Then I created a Calculated (calculation based on other columns) Column
• Named it ItemDisplay
  
  • Made it a Content Type
  • Inserted the following formula: 
  • Calculated (calculation based on other columns)
    =IF(MONTH(Today)=MONTH(DateDisplay),"1","0")
  • Finally made the Data Type Return a Single Line of Text.
• Next I added the web part, edited the current view
• Place a filter on it so it shows only Items, "ItemDisplay" is Equal to 1
  

What the calculated value means
=IF the current Month of (Today) EQUALS the Month of (DateDisplay)
Then set the value to 1, if not then set it to 0
The Web Part filter will then display only items Equal to 1

EDITED: I haven't been able to make this process automated, but at the beginning of each month, I just edit the current months items, don't make any changes, just save the item and the formula will kick in and display the month as a 1.  Hope this makes sense.
