It was released in 1986. I remember because I saw it on the first day of Grade 12, to get myself in the proper mood for my last year of high school.
Plus, as I recall, this was the first teen "comedy" that John Hughes had produced, after making more serious teen films like
The Breakfast Club (now THAT film was made in 1984, I think) and
Sixteen Candles (1983, I think?), and if I'm not mistaken,
Pretty in Pink might have been made in 1985 -- I've got this weird idea that Hughes made three Molly Ringwald movies in a row, and then he made
Ferris Bueller, and then he made
She's Having a Baby in 1988, and then he sold his soul with
Home Alone in 1990 and all the baby movies that came after that.
[ pause to check the
IMDB ]
Aha! Turns out my years were off a bit. Hughes has DIRECTED only eight movies (of which I have only seen four, in
bold):

2. Uncle Buck (1989)
3.
She's Having a Baby (1988)
4.
Planes, Trains & Automobiles (1987)
5.
Ferris Bueller's Day Off (1986)
6. Weird Science (1985)
7.
Breakfast Club, The (1985)
8. Sixteen Candles (1984)
But he has PRODUCED (and thus, in most if not all cases, WRITTEN) the following:
1. New Port South (2001) (producer)
2. Reach the Rock (1998) (producer)
3.

Plus he wrote a few National Lampoon films before he got into directing and producing.
