(I realize you've restricted the year to 2009, so that might be moot...) Really, what you have is a 28-day cycle, so here's how I would do it: FSET _cycle(x) ((x - '2008-12-08') / 7) % 4 REM Mon Tue Wed Thu Fri SATISFY [_cycle(trigdate()) == 0] MSG late% REM Mon Tue Wed Thu Fri SATISFY [_cycle(trigdate()) == 1] MSG off% REM Mon Tue Wed Thu Fri SATISFY [_cycle(trigdate()) == 2] MSG early% REM Mon Tue Wed Thu Fri SATISFY [_cycle(trigdate()) == 3] MSG swing% (You may need to adjust the numeric constants so the right shifts show up.) By subtracting from a known start date, it should work even across multiple years.
