I am not sure.

The ANSI standard for the DateAndTime protocol reads:

5.8.1.9 Message: dayOfWeek
Synopsis
Answer the number of the day in the week, in the local time of the 
receiver, which includes the receiver.
Definition: <DateAndTime>
Answer an <integer> between 1 and 7 inclusive representing the number of 
the day in the week, in
the local time of the receiver, which includes the receiver. Sunday is 1, 
Monday is 2, and so on.
Return Values
<integer> unspecified
Errors
None

So I deliberately implemented Week>>nameOfDay: to satisfy the standard.

Note. This is the ONE method that has changed with the introductuon of the 
Chronology package. Smalltalk 80 has Monday as day 1.

PS. New package with Chris Muller's Stopwatch functionality coming soon.

Cheers
