[Remind-Fans] an OMIT holiday moves forward Sun to Mon, Monday things that should move forward don't.

[hymie!]

If I understand correctly, then what you want do is something along these
lines:

Backstory, in America, July 4th is a holiday.  If it's a Sunday, then
the holiday moves to Monday; if it's a Saturday, then the holiday moves
to Friday.

rem 4 jul scanfrom [trigger(today()-7)] satisfy 1
# saturday
if (wkdaynum(trigdate()) == 6)
  omit 3 jul msg independence day
else
#sunday
  if (wkdaynum(trigdate()) == 0) 
    omit 5 jul msg independence day
  else
    omit 4 jul msg independence day
  endif
endif
