(a) When imprisonment is a part of the sentence, the term shall be fixed, and the time of its commencement and ending specified. An act to be done at the expiration of a term of imprisonment shall be done on the last day thereof, unless it be Sunday, and in that case, the day previous. Months shall be reckoned as calendar months.
(b) All sentences for criminal offenses of persons who at the time sentence is imposed are held in custody in default of bail, or otherwise, shall begin to run and be computed from the date of incarceration for the offense for which said sentence shall be imposed, unless the person sentenced shall then be undergoing imprisonment under a sentence imposed for any other offense or offenses, in which case the said sentence shall begin to run and be computed, either from the date of imposition thereof or from the expiration of such other sentence or sentences, as the court shall, in its discretion, direct.
(c) Any period of actual incarceration of a person awaiting trial, who thereafter before trial or sentence succeeds in securing provisional liberty on bail, shall be credited to the person in determining the termination date of sentence. Where a prisoner is hospitalized, the time spent in an institution under involuntary restraint is to be credited to the person when calculating the sentence under this subsection.
(d) The court shall direct whether the sentence of confinement of any criminal defendant by any court of this State shall be made to run concurrently or consecutively with any other sentence of confinement imposed on such criminal defendant. Notwithstanding the foregoing, no sentence of confinement of any criminal defendant by any court of this State shall be made to run concurrently with any other sentence of confinement imposed on such criminal defendant for any conviction of the following crimes:
