If such release date falls upon a Saturday, a Sunday, or on a Monday which is a legal holiday at the place of confinement, the prisoner may be released at the discretion of the warden or keeper on the preceding Friday. If such release date falls on a holiday which falls other than on a Saturday, Sunday, or Monday, the prisoner may be released at the discretion of the warden or keeper on the day preceding the holiday.”
