4. Q. How do I query on a specific month?
   
   A. In the Works database module, you can query for dates that fall in a particular month with the MONTH() function. The MONTH() function returns an integer from 1 to 12 specifying the month of the given date. For example, if you need to find records that have May in a field named "Birthday," use the steps below:
   
   
   1. On the Tools menu, click Create New Query.
   2. Click Query View.
   3. Press DELETE to remove any formula that appears.
   4. In the Birthday field, type the following formula:

      =month()=5

   5. On the View menu, click List to see the results of your query.
      
      NOTE: The examples in this question match all records where a date entry contains a month of May, regardless of the year. To find records in a certain year, use the YEAR function. For example, to find records only for May of 1995, use the following formula:

      =month(birthday)=5#and#year(birthday)=95
