Hawaii's custom of Aloha Friday slowly spread east to California, continuing around the globe until the 1990s, when it became known as Casual Friday. Today in Hawaii, alohawear is worn as business attire for any day of the week, and "Aloha Friday" is generally used to refer to the last day of the work week. Now considered Hawaii's term for "Thank God It's Friday" (TGIF), the phrase was used by Kimo Kahoano and Paul Natto in their 1982 song, "It's Aloha Friday, No Work 'til Monday", heard every Friday on Hawaii radio stations across the state.
