It includes explanation of INTNX function with practical examples which would help you to understand it. It helps sas intnx function answer the following questions. You would get answer to this question in the next example.

Multipliers and shift indexes can be used with the basic interval names to construct more complex interval specifications. The three parts of the interval name are as follows:. Increment is the number of intervals to shift the value of start-from. You must enclose alignment in quotation marks. Alignment can be one of these values:. Overview of DS2 Functions. General Function Syntax.

Sas intnx function

Increments a date, time, or datetime value by a given time interval, and returns a date, time, or datetime value. Interval can appear in uppercase or lowercase. Multipliers and shift indexes can be used with the basic interval names to construct more complex interval specifications. The general form of an interval name is as follows:. The three parts of the interval name are listed below:. For example, YEAR specifies yearly intervals. For example, the interval YEAR2 consists of two-year, or biennial, periods. For example, YEAR. Increment is the number of intervals to shift the value of start-from. You must enclose alignment in quotation marks. Alignment can be one of these values:. The increment is based on a starting date, time, or datetime value, and on the number of time intervals that you specify. The INTNX function returns the SAS date value for the beginning date, time, or datetime value of the interval that you specify in the start—from argument. The following example shows how to determine the date of the start of the week that is six weeks from the week of October 17, For more information about working with date and time intervals, see Date and Time Intervals.

To subtract an interval, supply a negative number to the increment argument. We can use the INTNX function to create a new column called plus5days that adds five days to each date in the date column:. Notice that the new column called plus5days contains the values in the date column with fives days added to them. For example, we can use the following code to subtract five days from each value in the date column:. Notice that the new column called minus5days contains the values in the date column with fives days subtracted from them. We can use the INTNX function to create a new column called firstmonth that contains the first day of the month for each date in the date column:.
