Date represents an abstraction for a given day of a given year. The Blue Book specifies the instance protocol of
Date in functional form, but does not actually define method names for most operations. Consequently, although all Smalltalk vendors provide basically the same functionality, there is some variation between the message names used. The general form is that
Date provides protocol for manipulating dates, while
Date class supports instance creation and general queries.
Objectworks\Smalltalk does not support
dayName or
dayIndex. Smalltalk/V supports the
dayIndex message with the days of the week numbered starting with Monday as day 1. However, because CLDT provides National Language Support features based on the POSIX.1 standard, the CLDT
dayIndex message answers Sunday as day 1.
