@MeganLegge Mitchell hit the nail on the head with his reponse. Pausing a workflow is a nice ability to deal with certain situations, but the real request here is to apply a calendar to a workflow or its steps and have the step wait until after a holiday to send an email. Managing a few calendars applied to workflows is a much better (and less work-intense) way to apply that logic than having to manually pause workflows on a certain date and then restart them again.
I’ve shared the same feedback in the linked form.
