Snap XMP Desktop includes a number of operations and functions specifically designed to help analyse dates. <\/p>\n\n\n\n

\n When a participant responds to a date response question they can enter a free format date. Examples of the date can include July 1st, 2020 or 1 Jul 20. The inbuilt operations enable date responses to be categorized by month, by day of the week or by custom specified ranges.\n<\/p>\n\n\n\n

\n The following steps show how to create a derived variable which categorizes the response, to a date question, into quarters of the year.\n<\/p>\n\n\n\n

<\/a>Step 1: Create the derived variable<\/h2>\n\n\n\n
    \n
  1. \n Open the Variables<\/strong> window \n \"VariablesIcon.png\"\n and click \n \"NewIcon.png\"\n  to add a new variable.\n<\/li>\n\n\n\n
  2. \n In Name<\/strong> enter Quarter as the derived variable name.\n<\/li>\n\n\n\n
  3. \n Set the Type<\/strong> to Derived and Response<\/strong> to Single.\n
    \n \"CreateDerivedVariable.PNG\"\n<\/li>\n<\/ol>\n\n\n\n

    <\/a>Step 2: Enter the date ranges<\/h2>\n\n\n\n
      \n
    1. \n In the Code list grid, enter Quarter 1 as the Label<\/strong> for the first quarter then in Values<\/strong> enter the date range Q1 >= 1 Jan 20 and Q1 < 1 Apr 20. Any appropriate date format can be used to specify the fixed dates.\n<\/li>\n\n\n\n
    2. \n Repeat this for the other quarter date ranges.\n<\/li>\n<\/ol>\n\n\n\n
      \"Code<\/figure>\n\n\n\n
        \n
      1. \n Alternatively, for this example we can use the MONTH<\/strong> function. This gives a number representing the month of the year (1=January, 12=December). Using that, we can set up the codes of the categorizing variable as follows:\n<\/li>\n<\/ol>\n\n\n\n
        \"Code<\/figure>\n\n\n\n

        \n Using the MONTH<\/strong> function here produces a derived variable that works for every year. This method also takes advantage of the fact that for a derived single<\/strong> variable, only the upper bound for each code value needs to be specified so that any respondent in the previous code will already have been captured by that code. \n<\/p>\n\n\n\n

        <\/a>Step 3: Using other built-in date functions<\/h2>\n\n\n\n

        \n Other built-in functions that may be used for extracting information from dates are shown in the table.\n<\/p>\n\n\n\n

        weekday<\/strong> \n<\/p><\/td>

        \n the day of the week 1=Monday, 7=Sunday <\/strong>\n<\/p><\/td><\/tr>

        weekday name<\/strong>\n<\/p><\/td>

        \n a literal representing the name of the weekday, for example, \u201cWednesday\u201d\n<\/p><\/td><\/tr>

        day<\/strong>\n<\/p><\/td>

        \n the day of the month 1 to 28, 29, 30 or 31 as appropriate\n<\/p><\/td><\/tr>

        month<\/strong>\n<\/p><\/td>

        \n the month of the year 1=January, 12=December\n<\/p><\/td><\/tr>

        month name<\/strong>\n<\/p><\/td>

        \n the name of the month, for example, \u201cJuly\u201d\n<\/p><\/td><\/tr>

        year<\/strong>\n<\/p><\/td>

        \n the four-digit year, for example, 2020\n<\/p><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

        \n You can build a similar derived variable to categorize replies according to the day of week, regardless of the month or the year, by using the weekday function in a similar way to the way the month function was used in the previous example.\n<\/p>\n\n\n\n
