INTCK and INTNX: All about SAS Dates and Computing Intervals between Dates

Posted on July 31, 2017December 12, 2019 by Dexlab

The INTCK and INTNX functions in SAS helps you compute the time between events. This technical blog is based on the timeline of living US presidents, sourced from a Wikipedia table. The table data shows the number of years and days between events.

So, let’s start.

Gaps between dates

To calculate the interval between two dates, you can use these two SAS functions:

The INTCK function returns the number of time units between dates. The time unit can be selected in years, months, weeks, days, or whatever you feel like.

The INTNX function helps you compute the date that is 308 days away in the future from a specific date. This was just an example to help you understand what it means. The INTNX function returns a SAS date that is particular number of time units away from a particular date.

These two functions share a complimentary bond: where one calculates the difference between two dates, the other entitles you to add time units to a specified date value. Also, the INT part in both the functions denotes INTervals, and the terms INTCK and INTNX means Interval Check and Interval Next, respectively.

DexLab Analytics offers intensive SAS certification courses for candidates..

How to calculate anniversary dates

These two prime functions tend to be useful in counting the number of anniversaries between two dates along with calculating a future anniversary date. Use the ‘CONTINUOUS’ option for the INTCK function and the ‘SAME’ option for the INTNX function in the following manner:

The ‘CONTINUOUS’ option in the INTCK function helps you count the number of anniversaries of one date that occur before a second date. For example, the statement

Years = intck('year', '30APR1789'd, '04MAR1797'd, 'continuous');

returns the value 7 because there are 7 full years (anniversaries of 30APR) between those two dates. Without the ‘CONTINUOUS’ option, the function returns 8 as 01JAN occurs 8 times between those dates.

The statement

Anniv = intnx('year', '30APR1789'd, 7, 'same');

returns the 7th anniversary of the date 30APR1789. In some ways, it returns the date value for 30APR1796.

The most exciting part about these two functions is that they automatically handle leap years! Yes, you read that right. If you ask for the number of days within two dates, the INTCK function will show leap days in the result. If an event takes place on a leap day, and you ask the INTNX function to reveal the anniversary date, it will report 28FEB of the next year to the next anniversary date.

An algorithm calculating years and days between events

Go through the following algorithm to calculate the number of years and days between dates in SAS:

Use the INTCK function with the ‘CONTINUOUS’ option to calculate the number of completed years between two dates
Use the INTNX function to discover a third date, i.e. anniversary date, which is the same month and day like the start date, but takes place less than a year before the end date.
Use the INTCK function to ascertain the number of days occurring between the anniversary date and the end date.

Here are the data steps that enable you to compute the time interval in years and days between the first few US presidential inaugurations and deaths.

data YearDays;
format Date prevDate anniv Date9.;
input @1  Date anydtdte12.
      @13 Event $26.;
prevDate = lag(Date);
if _N_=1 then do;                               /* when _N_=1, lag(Date)=. */
   Years=.; Days=.; return;            /* set years & days, go to next obs */
end;
Years = intck('year', prevDate, Date, 'continuous'); /* num complete years */
Anniv = intnx('year', prevDate, Years, 'same');      /* most recent anniv  */
Days = intck('day', anniv, Date);                    /* days since anniv   */
datalines;
Apr 30, 1789 Washington Inaug
Mar 4, 1797  J Adams Inaug
Dec 14, 1799 Washington Death
Mar 4, 1801  Jefferson Inaug
Mar 4, 1809  Madison Inaug
Mar 4, 1817  Monroe Inaug
Mar 4, 1825  JQ Adams Inaug
Jul 4, 1826  Jefferson Death
Jul 4, 1826  J Adams Death
run;
 
proc print data=YearDays;
var Event prevDate Date Anniv Years Days;
run;

In a nutshell, the INTCK and INTNX functions are consequential for calculating intervals between dates. In this blog, I discussed about two-less-popular options inn SAS, for more such SAS training related blogs, follow us at DexLab Analytics.

How to Determine the Size of a SAS Data Set

Posted on May 3, 2017November 8, 2019 by Dexlab

When program codes, applications and SAS data sets are developed, enough attention is often not given to EFFECIENCY, especially during the initial phases of development. Since, data size and system conduct can influence a program or an application’s functioning, SAS users need to access information about a data set’s size and content. To ascertain how much disk space a data set is using, users can easily do a few calculations to learn to access metadata content and attain the important information. Determine, estimate and understand information with this following tip, which helps improve SAS performance and fine-tuning of techniques.

Implementing PROC SQL and DICTIONARY.TABLES

The SAS system accumulates valuable information (also known as metadata) about all-familiar SAS libraries, indexes, data sets (tables), system options, views, catalogs, macros and an assemblage of other “read-only” tables called Dictionary tables and SASHELP views. TABLES, a particular Dictionary table and its SASHELP view equivalent, VTABLE, consists details about a SAS session’s data set. Check the following PROC SQL code as its specification will help us get access to the contents of four columns observed in the TABLES Dictionary table, namely BNAME, MEMNAME, MEMTYPE and FILESIZE to exhibit the size of the CARS data set.

PROC SQL and Dictionary.TABLES:

PROC SQL ;
  TITLE ‘Filesize for CARS Data Set’ ;
  SELECT LIBNAME,
         MEMNAME,
         FILESIZE FORMAT=SIZEKMG.,
         FILESIZE FORMAT=SIZEK.
    FROM DICTIONARY.TABLES
      WHERE LIBNAME = ‘SASHELP’
        AND MEMNAME = ‘CARS’
        AND MEMTYPE = ‘DATA’ ;
QUIT ;

Results

Analysis

The above results show that the CARS data set filesize is 192KB.

Nota bene: If the SIZEKMG.format is mentioned in a format=option, SAS ascertains whether it should apply KB for kilobytes, MB for megabytes or GB for gigabytes, and divide the filesize value with the help of one of the following values:

KB 1024

MB 1048576

GB 1073741824

Using PROC PRINT and SASHELP.VTABLE

In the following example, the provisions of a PROC PRINT are explained to access the constituents of three columns found in the VTABLE SASHELP view, particularly LIBNAME, MEMNAME and FILESIZE to exhibit the size of the CARS data set.

RUN ;

Results

Using DATA _NULL_, SASHELP.VEXTFL and CALL SYMPUTX

Lastly, a DATA_NULL_ is depicted to approach the contents of the VEXTFL SASHELP view with a FILENAME statement. An assignment statement is specified to determine the FILESIZE value for the size of the CARS data set. The CALL SYMPUTX left supports and chops off the trailing blanks from the digital FILSESIZE value of 196608.

  /* Calculate the Filesize in MB */
  FILESIZE = FILESIZE / (1024 ** 2) ;
  CALL SYMPUTX (‘FILESIZE’,FILESIZE) ;

How to Read Data With SAS JSON Libname Engine

Posted on January 9, 2017November 7, 2019 by Dexlab

To those of you unaware of the developments in the SAS world, JSON is the new XML and the number of users who need to access JSON has really grown in the recent times. This is mainly due to proliferation of REST-based APIs and other web services. A good reason for JSON being so popular is the fact that it is structured data in the format of text. We have been capable of offering simple parsing techniques, which make use of data step and most recently PROC DS2. Now with the SAS 9.4 and Maintenance 4 we now have a built-in libname engine for the JSON XML.

As a SAS training institute we strive to keep our students updated with the latest developments in the field of data analytics even after they move on. Continue reading “How to Read Data With SAS JSON Libname Engine”
