Using CRSP Date Formats, Informats, and Functions
Historically, CRSP has used two different methods to represent dates, and SAS has used a third. The SASECRSP engine provides 23 functions, 15 informats, and 10 formats to enable you to easily translate the dates from one internal representation to another. See the section Understanding CRSP Date Formats, Informats, and Functions for details.
