Tennessee Code Title 40. Criminal Procedure § 40-35-307

(a) A defendant receiving probation may be required to serve a specific portion of the sentence in periodic confinement in the local jail or workhouse for up to one (1) year with probation for a period of time up to and including the statutory maximum time for the class of the conviction offense.

(b) If the court sentences a defendant to a term of probation involving periodic confinement, it shall specify:

(c) The court may include in the judgment of conviction suitable provisions to the officer to whose custody the defendant is committed as will ensure that the defendant will be allowed to serve the sentence on nonconsecutive days which may include, but are not limited to, weekends, between hours to be specified in the judgment, which provisions or directions may be revoked, suspended or amended from time to time by the sentencing court until the period of probation begins.

(d) The sheriff, warden, superintendent or other official having responsibility for the safekeeping of the defendant in any local jail or workhouse shall adopt procedures for the release of the defendant at the time specified in the order of judgment and for receiving the defendant back into custody at the specified times.  Willful failure of the official to comply with the directions of the court constitutes contempt of court, punishable as provided by law for contempt generally.

(e) Failure of the defendant to surrender to the custody of the sheriff, warden, superintendent or other official responsible for the defendant's safekeeping in the local jail or workhouse within the time specified in the order of judgment constitutes grounds for the revocation or modification of probation in the discretion of the court.  The defendant may elect to serve the defendant's entire sentence of confinement on consecutive days;  provided, that a failure to comply with subsection (c) or (d) shall give the court the authority, upon a finding of a violation, to impose a sentence of continuous confinement in a local jail or workhouse or, unless prohibited by § 40-35-104(b), in the department of correction for the remainder of the full sentence originally imposed.

(f) At any time during the period of periodic confinement, the defendant may apply to have the balance of the periodic confinement sentence served on probation without further confinement.  The application may be made at no less than two-month intervals.
