Full Text of A.R.S. § 13-903
A.R.S. § 13-903 is the Arizona statute on calculation of periods of probation. It sets out procedure and rules rather than defining an offense, so no offense class or sentence attaches to this section on its own.
A. A period of probation commences on the day it is imposed or as designated by the court, and an extended period of probation commences on the day the original period lapses.
B. If a court determines that the defendant violated a condition of the defendant’s probation but reinstates probation, the period between the date of the violation and the date of restoration of probation is not computed as part of the period of probation. If it is determined that the defendant is not a violator, there is no interruption of the period.
C. The running of the period of probation shall cease during the unauthorized absence of the defendant from the jurisdiction or from any required supervision and shall resume only upon the defendant’s voluntary or involuntary return to the probation service.
D. The running of the period of probation shall cease during the period from the filing of the petition to revoke probation to the termination of revocation of probation proceedings, except that if a court determines that the defendant is not a violator, there is no interruption of the period of probation.
E. If probation is imposed on one who at the time is serving a sentence of imprisonment imposed on a different conviction, service of the sentence of imprisonment shall not satisfy the probation.
F. Time spent in custody under section 13-901, subsection F shall be credited to any sentence of imprisonment imposed upon revocation of probation.

How § 13-903 Affects an Arizona Case
§ 13-903 usually matters because of how it interacts with the charge someone is actually facing. We read it alongside the charging statute, because a definition or a procedural rule frequently decides what the State must prove, what a judge may impose, or what relief is available afterward.
