1,000 Hours is the debut EP by American rock band Green Day, released in April 1989 through Lookout Records. Through a shared interest in music, school friends Billie Joe Armstrong and Mike Dirnt formed the band Sweet Children. With the addition of drummer John Kiffmeyer, they played at the local punk club 924 Gilman Street in Berkeley, California, where they started attracting a following. After playing a show with the Lookouts, one of their members, Larry Livermore, signed Sweet Children to his label Lookout Records. They co-produced their debut EP, 1,000 Hours, with Andy Ernst at the Art of Ears Studio in San Francisco, California, in early 1989.

Critics praised the production quality of the 1,000 Hours EP. Before its release, Sweet Children changed their name to Green Day, which Livermore said would make it difficult to shift copies of the EP. They played their last show as Sweet Children in April 1989, and played their first show as Green Day in May 1989, supporting Operation Ivy at Gilman. They subsequently played a show in July 1989 with Necromancy, before the members participated in other bands. 1,000 Hours was later included in the 1,039/Smoothed Out Slappy Hours (1991) compilation alongside their other early releases.
