Sas week format

Our tutorials reference a dataset called "sample" in many examples.

You can use the following functions in SAS to get the day of the week from a date:. The following example shows how to use each of these functions in practice. Suppose we have the following dataset in SAS that shows the birth date for seven individuals:. We can use the following code to create a new dataset that contains two new variables that show the day of the week as a number and the day of the week as a name for the birth date of each individual:. The two new variables show the day of the week for each birth date as a number and as a name. The following tutorials explain how to perform other common tasks in SAS:.

.

Here, sas week format, we start with dataset with two different character variables we want to convert to "true" date variables. You can add the prefix 'dt' to any of the above codes except 'hour' to indicate a date-time interval e.

.

Writes date values as the day of the week and the date in the form day-of-week , month-name dd , yy or yyyy. Formats by Category. BDA Format. BDN Format. BDT Format. BDX Format. BDZ Format. BLX Format. BLZ Format. BTM Format.

Sas week format

If the sas-date argument is not specified, the WEEK function returns the week-number value of the current date. The following descriptors can be specified in uppercase or lowercase characters. Sunday is considered the first day of the week. The number-of-the-week value is represented as a decimal number in the range 0— Week 53 has no special meaning. Monday is considered the first day of the week and week 1 of the year is the week that includes both January 4 and the first Thursday of the year.

Alternatively, date creation functions like MDY can be used to construct date constants. University Libraries. Specifically, it determines the number of days that should be used to characterize the period of time in a month or year. The following tutorials explain how to perform other common tasks in SAS:. Specifies that a person's age will be computed. Date creation functions construct new date or datetime variables based on their inputs. You can add the prefix 'dt' to any of the above codes except 'hour' to indicate a date-time interval e. Regardless of how the researcher records dates or times in their dataset, SAS "internally" records datetime variables as integers. This helps to simplify the computations when computing the differences between dates. Date computation or "date difference" functions carry out arithmetic operations on dates; for example, computing the elapsed time between two dates. DAY - Given a number or a variable representing a date or datetime, returns the day as a number from If you'd like to try out any of the examples on this page, you can recreate the sample datasets in your instance of SAS by running this code first:. Youtube Youtube. The same calendar dates are represented in both columns, but they use different encodings. When writing a SAS script, there may be times when you need to refer to a single, specific date.

If the sas-date argument is not specified, the WEEK function returns the week-number value of the current date. The following descriptors can be specified in uppercase or lowercase characters.

Table 1: SAS internal values for selected dates. Twitter Twitter. Facebook Facebook. Lastly, we also touch on date constants , which are useful if you want to subset a dataset based on date values, or calculate a date variable based on a reference date. Suppose we have the following dataset in SAS that shows the birth date for seven individuals:. February 22nd, is on a Tuesday , which is the 3rd day of the week. The same calendar dates are represented in both columns, but they use different encodings. Here the QTR function extracts the quarter value from the date value variable DOB and saves it in the new numeric variable quarter. In SAS 9. Flickr Flickr. And so on. Tags: statistics , tutorials.
