1,000 Hours is the debut EP by the American punk rock band Green Day. It was released in April 1989 through Lookout! Records, the label that nurtured the band's development in their early years before their signing with a major label in 1993.
1,000 Hours was recorded in 1988 while the band was still named "Sweet Children", and released in April 1989, 2 weeks after the band changed their name to Green Day, but on vinyl only, with several different colors of vinyl available [red, blue, green, purple, yellow, and clear] in limited quantities. Upon its release, it was also available with a pink cover [black vinyl only]. Shortly after it was recorded, the band changed their name to Green Day, despite the objections of Lookout Records' owner Lawrence "Larry" Livermore.
