He will be released in seven days from the day he was first detained. BTW, the ex-inmates answering these questions do not consider seven days a "sentence"

You might be able to call the facility and ask for a counselor. In most cases, these people are very helpful. However, your inmate already knows his release date. Once they have made it to a work camp, the release date is around the corner.

By law, they certainly should. Why would you think they wouldn't?

To be granted the option of parole from the judge who sentenced you, there must be a provision in the Judgment and Commitment Order specifying the offender be eligible for parole.

Depending on his Judgment and Commitment Order, he might get a parole hearing at the four year mark. The year in county counts towards this sentence

Call the facility and ask to speak to a counselor. Or, ask YOUR inmate, they definitely know their out date

He has a maximum sentence date of Oct 2018, with a projected release date of Jan 2018. If he stays calm and does not have any incident reports, he will get out in January. Tell him to chill and just do the remaining time, "don't let the time do him"

In federal, he will do 85% of the 60 months or 51 months. If he is qualified, they might offer him RDAP. This is a nine-month residential drug and alcohol program that reduces the sentence by 12 months (with an automatic six months of halfway house).

Most facilities do not offer the release dates online. If the inmate is unaware of their own release date, then you might call the counselor there and politely ask. They might help you with that information.

In short, it means there is a warrant from someone else for a totally different charge. A "detention hold" is legally binding direction to the current detention facility ONLY release you into their custody after you have served your time for the current sentence.
