JULDATE(date)

Arguments

date: specifies a SAS date value.

The JULDATE function converts a SAS date value to a five- or seven-digit Julian date. If date falls within the 100-year span defined by the system option YEARCUTOFF=, the result has five digits: the first two digits represent the year, and the next three digits represent the day of the year (1 to 365, or 1 to 366 for leap years). Otherwise, the result has seven digits: the first four digits represent the year, and the next three digits represent the day of the year. For example, if YEARCUTOFF=1920, JULDATE would return 97001 for January 1, 1997, and return 1878365 for December 31, 1878.

Comparisons

The function JULDATE7 is similar to JULDATE except that JULDATE7 always returns a four digit year. Thus JULDATE7 is year 2000 compliant because it eliminates the need to consider the implications of a two digit year.

The following SAS statements produce these results:
