Hello,

: The problem seems to be that there is no function
: calendar-last-day-of-week.

Well, there is, it's called `calendar-week-end-day'.

This returns the index into 'calendar-day-name-array.  Note that the
variable 'calendar-week-start-day should be set properly (it defaults
to 0 = $SUNDAY, while I set this to 1, meaning $MONDAY).

This will only get you as far as computing the name of the day.
Computing a date and/or timestamp for an instance of that day name
relative to a date is quite another matter.  The file
calendar/time-date.el might provide useful stuff for doing so.
