thanks Alain for your detailed explanation. I forgot about the -/--
possibilities. And that explains why in tests which I did with
Pentecost in an OMIT .... MSG pentecôte statement Mother's day skipped
back to Saturday instead of Sunday.

My solution only worked without any OMIT between
Pentecost and the first Sunday in June.
