Where a person is under more than one indeterminate sentence, the sentences shall be calculated as follows:
(a)[Effective until 9/1/2025] If the sentences run concurrently, the time served under imprisonment on any of the sentences shall be credited against the minimum periods of all the concurrent indeterminate sentences and against the terms of all the concurrent determinate sentences. The maximum term or terms of the indeterminate sentences and the term or terms of the determinate sentences shall merge in and be satisfied by discharge of the term which has the longest unexpired time to run;(a)[Effective 9/1/2025] If the sentences run concurrently, the time served under imprisonment on any of the sentences shall be credited against the minimum periods of all the concurrent sentences, and the maximum terms merge in and are satisfied by discharge of the term which has the longest unexpired time to run;(b)[Effective until 9/1/2025] If the defendant is serving two or more indeterminate sentences which run consecutively, the minimum periods of imprisonment are added to arrive at an aggregate minimum period of imprisonment equal to the sum of all the minimum periods, and the maximum terms are added to arrive at an aggregate maximum term equal to the sum of all the maximum terms, provided, however, that both the aggregate maximum term and the aggregate minimum period of imprisonment shall be subject to the limitations set forth in paragraphs (e) and (f) of this subdivision, where applicable;(b)[Effective 9/1/2025] If the sentences run consecutively, the minimum periods of imprisonment are added to arrive at an aggregate minimum period of imprisonment equal to the sum of all the minimum periods, and the maximum terms are added to arrive at an aggregate maximum term equal to the sum of all the maximum terms, provided, however, that both the aggregate maximum term and the aggregate minimum period of imprisonment shall be subject to the limitations set forth in paragraphs (c) and (d) of this subdivision, where applicable;(c)[Effective until 9/1/2025] If the defendant is serving two or more determinate sentences of imprisonment which run consecutively, the terms of the determinate sentences are added to arrive at an aggregate maximum term of imprisonment, provided, however, that the aggregate maximum term of imprisonment shall be subject to the limitations set forth in paragraphs (e) and (f) of this subdivision, where applicable.(c)[Effective 9/1/2025](i) Except as provided in subparagraph (ii) or (iii) of this paragraph, the aggregate maximum term of consecutive sentences imposed for two or more crimes, other than two or more crimes that include a class A felony, committed prior to the time the person was imprisoned under any of such sentences shall, if it exceeds twenty years, be deemed to be twenty years, unless one of the sentences was imposed for a class B felony, in which case the aggregate maximum term shall, if it exceeds thirty years, be deemed to be thirty years. Where the aggregate maximum term of two or more consecutive sentences is reduced by calculation made pursuant to this paragraph, the aggregate minimum period of imprisonment, if it exceeds one-half of the aggregate maximum term as so reduced, shall be deemed to be one-half of the aggregate maximum term as so reduced;(ii) Notwithstanding subparagraph (i) of this paragraph, the aggregate maximum term of consecutive sentences imposed for the conviction of two violent felony offenses committed prior to the time the person was imprisoned under any of such sentences and one of which is a class B violent felony offense, shall, if it exceeds forty years, be deemed to be forty years;(iii) Notwithstanding subparagraphs (i) and (ii) of this paragraph, the aggregate maximum term of consecutive sentences imposed for the conviction of three or more violent felony offenses committed prior to the time the person was imprisoned under any of such sentences and one of which is a class B violent felony offense, shall, if it exceeds fifty years, be deemed to be fifty years;(d)[Effective until 9/1/2025] If the defendant is serving one or more indeterminate sentences of imprisonment and one or more determinate sentence of imprisonment which run consecutively, the minimum term or terms of the indeterminate sentence or sentences and the term or terms of the determinate sentence or sentences are added to arrive at an aggregate maximum term of imprisonment, provided, however, (i) that in no event shall the aggregate maximum so calculated be less than the term or maximum term of imprisonment of the sentence which has the longest unexpired time to run; and (ii) that the aggregate maximum term of imprisonment shall be subject to the limitations set forth in paragraphs (e) and (f) of this subdivision, where applicable. (d)[Effective 9/1/2025] The aggregate maximum term of consecutive sentences imposed upon a juvenile offender for two or more crimes, not including a class A felony, committed before he has reached the age of sixteen, shall, if it exceeds ten years, be deemed to be ten years.

If the additional term or terms imposed shall run consecutively to the said undischarged term, such additional term or terms shall commence when the prisoner is received in the appropriate institution as provided in subdivisions one and two of this section. The term or terms of such imprisonment shall be calculated and such other pertinent provisions of this section applied in the same manner as where a person is under more than one sentence in this state as provided in this section.3.[Effective until 9/1/2025] Jail time. The term of a definite sentence, a determinate sentence, or the maximum term of an indeterminate sentence imposed on a person shall be credited with and diminished by the amount of time the person spent in custody prior to the commencement of such sentence as a result of the charge that culminated in the sentence. In the case of an indeterminate sentence, if the minimum period of imprisonment has been fixed by the court or by the board of parole, the credit shall also be applied against the minimum period. The credit herein provided shall be calculated from the date custody under the charge commenced to the date the sentence commences and shall not include any time that is credited against the term or maximum term of any previously imposed sentence or period of post-release supervision to which the person is subject. Where the charge or charges culminate in more than one sentence, the credit shall be applied as follows: (a) If the sentences run concurrently, the credit shall be applied against each such sentence;(b) If the sentences run consecutively, the credit shall be applied against the aggregate term or aggregate maximum term of the sentences and against the aggregate minimum period of imprisonment.

In any case where a vacated sentence also includes a period of post-release supervision, all time credited against the period of post-release supervision shall be credited against the period of post-release supervision included with the new sentence. In the event a period of post-release supervision is not included with the new sentence, such period shall be credited against the new sentence.6. Escape.
