ABSTRACT

Date Package

This generic package provides arithmetic and logical operations for dates. It strongly parallels the required CALENDAR package, but differs primarily in the range of dates handled. Like CALENDAR, routines such as SPLIT, MONTH, DAY, and YEAR are available.

The differences between this package and CALENDAR are reflected in the range of dates, the inclusion of a DAY_NAME function, and the ability to specify a date with a year and an annual Julian day number *. A day is the smallest unit of time in this package.

An important feature is the ability to subtract dates over the full range of years. Thus, you can for example, calculate the number of days between 10/15/1986 and 1/1/1988. Another important feature is the ability to add (or subtract) x number of days from a date and obtain a date x days in the future (or past).
