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:.

Regardless of how the researcher records dates or times in their dataset, SAS "internally" records datetime variables as integers. In this tutorial, we show how to compute new variables from dates and times using two major types of date functions: extraction-type functions and computation-type functions. This helps to simplify the computations when computing the differences between dates. Skip to content Menu. You can use the following functions in SAS to get the day of the week from a date:.
