 Description

     DAY() is a date conversion function used to convert a date value to the
     day of a month.  This function is used in combination with CMONTH() and
     YEAR() to format dates.  In addition, it is often used in various date
     calculations.

 Examples

     .  These examples show the DAY() function used several ways:

        ? DATE()                             // Result: 09/01/90
        ? DAY(DATE())                        // Result: 1
        ? DAY(DATE()) + 1                    // Result: 2
        ? DAY(CTOD("12/01/94"))              // Result: 1

     .  This example uses DAY() in combination with CMONTH() and
        YEAR() to format a date value:

        ? CMONTH(DATE()) + STR(DAY(DATE())) +;
           "," + STR(YEAR(DATE()))      // Result: June 15, 1990
