When Will He Be Released on 120 Days With Time Served?

Working through the math: with 42 days of time served credited against a 120-day sentence, he has 78 days remaining from his June 1 sentencing date. That puts the estimated release date around August 18, 2016.

Good time credit on a sentence this short is minimal to nonexistent. Most jurisdictions do not apply meaningful good time reductions on sentences under six months, so August 18 is the realistic target date rather than something meaningfully earlier, unless there is severe overcrowding at the facility, which can occasionally prompt early releases to free up bed space.

The one variable worth confirming is exactly how his jurisdiction calculates the credit. Some courts count from the date of arrest to the date of sentencing when applying time served, while others use a slightly different method. The 42 days credited should already reflect his April 27 arrest date through sentencing, but it is worth verifying that number with his attorney or the court clerk to make sure the full credit was applied correctly.
