A while ago there was some discussion about the relation of these terms (see here and here). I personally like Seerveld’s definition of reformational; it saved me worrying about whether I was neocalvinist, neokuyperian, neodooyeweerdian, or perhaps even neoseerveldian!
“Reformational” identifies (1) a life that would be deeply committed to the scriptural injunction not to be conformed to patterns of this age but to be re-formed by the renewal of our consciousness so that we will be able to discern what God wills for action on earth (cf. Romans 12:1-2); and (2) an approach in history to honour the genius of the Reformation spearheaded by Luther and Calvin in the sixteenth century, developed by Groen van Prinsterer and Abraham Kuyper in the nineteenth century, as a particular christian tradition out of which one could richly serve the Lord; with (3) a concern that we be communally busy reforming in an ongoing way rather than standing pat in the past tense (ecclesia reformata semper reformanda est).
