Yes, it just rolls to the end of the next month. I sent my nomination form in mid-October but for various reasons, my Nominator didn't receive a link to the form until early December. The form was completed recently, so it should be considered a complete application for the end of December and I'll hear at the end of January.
If your nominator doesn't get it done by COB on the 3rd, and gets it done later in the month, your application will be evaluated after being considered complete at the end of Jan., and you should hear by the end of Feb.
