Lori Loughlin's husband is free to leave the house earlier than expected ... it's only one day, but it's better than nothing.
Mossimo Giannulli was set to be released from home confinement April 17, which is a Saturday, but it's common policy to grant release on the last preceding weekday if their freedom date falls on a weekend.
So, according to the Federal Bureau of Prisons, Lori's hubby was eligible to get off home confinement Friday, April 16 ... which is what just happened.
As we reported ... Mossimo was originally supposed to be locked up behind bars until the 17th, but got sprung a couple weeks early to serve out the remainder of his sentence at home.
As you'll recall ... Lori pled guilty last May to 1 count of conspiracy to commit wire and mail fraud. She and Mossimo were accused ofpaying $500k in bribes to get their daughters into USC and faking a photo that made it look like the girls were college-caliber rowers.
Mossimo pled guilty to 1 count of conspiracy to commit wire and mail fraud and 1 count of honest services wire and mail fraud. He was sentenced to 5 months, but like we said ... looks like he caught a little break.
