For the past few years the Cubs have been putting out three versions of their season schedule. The first comes out in the fall, as soon as the next year's schedule is released. The second schedule is a special Cubs Convention version. The final version comes out in March and it is the one they use for the rest of the year.
This is the 2017 early version. Times are listed for just the home games. There is not ticket information or promotions listings. It's just the bare-bones schedule.
