What attribute do SAS date values primarily represent?

The number of seconds since a base date.
The number of days since a base date.
The number of hours since a base date.
The number of minutes since a base date.

The correct answer is: The number of days since a base date.

SAS date values are designed to represent the number of days that have elapsed since a specific base date, which is set to January 1, 1960. This system allows SAS to handle and perform computations involving dates efficiently. Each date value is stored as a numeric value, where the integer corresponds directly to the number of days from that base date. This means that a SAS date value of zero corresponds to January 1, 1960, a value of one corresponds to January 2, 1960, and so forth. Understanding this attribute is crucial for anyone using SAS because it influences how date calculations are performed, how dates are manipulated, and how data is analyzed. The other options represent time units that are not how SAS fundamentally handles dates, which could lead to confusion or incorrect calculations in a programming context.
