Hmmm.. tricky.  How about:

# Get the date of Christmas
REM 25 December SCANFROM [today()-14] SATISFY 1
SET christmas trigdate()

# If Christmas is on a Sunday, then feast is on the 30th
IF wkdaynum(christmas) == 0
REM 30 December +2 MSG Holy Family (F)
ELSE
# Else it's on the Sunday following Christmas
REM Sun 25 December +2 MSG Holy Family (F)
ENDIF

It might be possible to do it all in one REM command with a SATISFY
expression.  Anyone up for that? :)

Regards,

David.
