According to this Spin report, Green Day will be releasing their upcoming full length, 21st Century Breakdown on May 15th - a Friday - rather than May 20, 2009 as originally announced.

The band is also planning to debut the first single from the record, "Know Your Enemy," in mid-April through digital retailers and radio. Spin describes the song as "like an outtake from the Dookie sessions."

The record is their first since 2004's American Idiot.
