Section 65.15 - Calculation of periods of probation and of conditional discharge1. A period of probation or a period or additional period of conditional discharge commences on the day it is imposed. Multiple periods, whether imposed at the same or at different times, shall run concurrently.2. When a person has violated the conditions of his or her probation or conditional discharge and is declared delinquent by the court, the declaration of delinquency shall interrupt the period of the sentence as of the date of the delinquency and such interruption shall continue until a final determination as to the delinquency has been made by the court pursuant to a hearing held in accordance with the provisions of the criminal procedure law. Any order for the installation and maintenance of a functioning ignition interlock device imposed pursuant to section 60.21 of this title shall remain in effect throughout the delinquency and the court may extend the period of such installation and maintenance by the period of the delinquency; provided, however, that the defendant shall get credit for any period where the device was installed and maintained during the delinquency.3.[Effective until 9/1/2025] In any case where a person who is under a sentence of probation or of conditional discharge is also under an indeterminate or determinate sentence of imprisonment, imposed for some other offense by a court of this state the service of the sentence of imprisonment shall satisfy the sentence of probation or of conditional discharge unless the sentence of probation or of conditional discharge is revoked prior to the next to occur of parole or conditional release under, or satisfaction of, the sentence of imprisonment. Provided, however, that the service of an indeterminate or determinate sentence of imprisonment shall not satisfy a sentence of probation if the sentence of probation was imposed at a time when the sentence of imprisonment had one year or less to run.3.[Effective 9/1/2025] In any case where a person who is under a sentence of probation or of conditional discharge is also under an indeterminate sentence of imprisonment, or a reformatory sentence of imprisonment authorized by section 75.00, imposed for some other offense by a court of this state the service of the sentence of imprisonment shall satisfy the sentence of probation or of conditional discharge unless the sentence of probation or of conditional discharge is revoked prior to the next to occur of parole or conditional release under, or satisfaction of, the sentence of imprisonment.
