Which season of Full House premiered on September 17, 1991?

Season five of Full House premiered on September 17, 1991.

The season originally aired on ABC from September 17, 1991, through May 12, 1992, and contained 26 episodes. It marked an important change in the show’s schedule: Full House moved to Tuesday nights full-time after spending much of its earlier run on Fridays.

Season five also expanded the Tanner family. Jesse Katsopolis and Rebecca Donaldson became parents to twin boys, Nicky and Alex, while Kimmy Gibbler—previously a recurring character—became a regular. Michelle Tanner’s growing role continued to shape many of the season’s storylines.

A common mix-up comes from the show’s original broadcast history. The first four seasons had aired from 1987 through 1991, so the September 1991 premiere was the beginning of the fifth season, not the fourth. The season’s premiere date is also distinct from the series premiere, which occurred on September 22, 1987.
