There is a problem with that approach Ron. If the 1st of Jan is say a
Saturday, your formula returns the Monday date. But that will be the New

Well, there are places or businesses where that is the case. But not in the
businesses that I've been involved in.

And if so, then the OP should include those holiday dates.
