Under New York Law, an intermittent term is a revocable sentence which is served on days or weekends as the court specifies in its order. This kind of sentence is not available for second or persistent felony offenders and is only applicable where the person is sentenced for a Class D or Class E felony or for a misdemeanor or violation. The time is calculated as running from the day the sentence is imposed until the term expires. Critically, regardless of whether the person is in jail or not on the specific day, the time continues to run. So while credit against the term of the sentence is accorded for jail time, it is not for good time.
An Intermittent sentence has many benefits. For instance, it allows one to hold a job, remain with family, and reap the benefits of other members in the community. However, is not without some risk. In particular, in some cases, persons serving weekend sentences have been persuaded by other offenders to bring contraband into the jail. If one is caught bringing drugs, for instance, into the jail it will result in serious problems.
