Where does the name Green Day come from?
There are several different ideas floating around about this. The term Green Day refers to a day that is spent smoking pot, and is slang in the Bay Area from which Green Day originates. Though they were originally called Sweet Children, another band was named Sweet Baby, so they decided to change to Green Day because they liked it more. Another idea present is that while stoned out of their minds they were watching Sesame Street and a character on the show said the phrase Green Day and they liked it.
