# How do you get the month difference in SAS?

You can use the INTCK function to calculate the difference between two dates in SAS. This function requires you to define the interval, the start date, and the end date. Depending on the interval, it returns you the difference in days, weeks, months, etc.

## How do you get the month difference in SAS?

You can use the INTCK function to calculate the difference between two dates in SAS. This function requires you to define the interval, the start date, and the end date. Depending on the interval, it returns you the difference in days, weeks, months, etc.

### How do you use Intck?

Returns the number of interval boundaries of a given kind that lie between two dates, times, or datetime values….Example 1: Interval Examples Using INTCK.

SAS Statement Result
y=trim(‘year ‘); date1=’1sep2005’d + 300; date2=’1sep2013’d – 300; newyears=intck(y, date1, date2); put newyears; 6

#### How do you calculate age in SAS?

To compute age using a date of birth and the current date, use the following code: DATA birth; INPUT id birthday MMDDYY6.; today = DATE(); days = today – birthday; age = floor(days / 365); DATALINES; 01 122275 02 010865 03 030586 . . RUN; The input format MMDDYY6.

Can you subtract dates in SAS?

You can use the INTCK function in SAS to quickly calculate the difference between two dates in SAS. where: interval: Interval to calculate (day, week, month, year, etc.)

How do you impute the last day of the month in SAS?

To find the last day of the month, the alignment should be set to ‘END’ or ‘E’. This will increment the starting date so that it falls on the last day of the month. Instead of concatenating the ’01’ to the starting value, the ANYDTDTE informat can be used to create a SAS date from just the year and month.

## What is Intnx function in SAS?

Increments a SAS date, time, or datetime value encoded as a DOUBLE, and returns a SAS date, time, or datetime value encoded as a DOUBLE.

### What is the difference between Intck and Intnx functions in SAS?

Difference between INTNX and INTCK functions These two functions complement each other: INTCK computes the difference between two dates, while INTNX enables you to add time units to a date value.

#### How does SAS calculate the number of months between two dates?

If you set the method argument equal to ‘C’ when you calculate the difference in months, SAS calculates the number of complete months between two dates. So, although 22JUN2020 and 20JUL2020 belong to different months, the number of completed months between these dates is zero.

What is the default interval type in SAS?

The default method in SAS is ‘D’. However, if you have a date-time variable instead of a date variable, your interval must contain ‘dt’. So, ‘dtday’, ‘dtmonth’, ‘dtyear’, etc.

How many days are in a decimal month?

The problem is that decimal months are not really defined; in fact, because some months have 30 days and some months have 31 days and some months have 28 or 29 days, I don’t think you will find a unique answer, and I don’t think there is anything programmed into SAS that will provide decimal months.

## How do I calculate the difference in days between two dates?

Firstly, a simple data set will be created with two columns with dates. Secondly, the INTCK function will be used to calculate the difference in days between the two variables. Finally, two examples demonstrate the use of the method argument. format mydate1 mydate2 date9.; input mydate1 :date9. mydate2 :date9.;
