At first, I was thinking it might have been Tuesday in the U.S., but Monday outside the U.S. But then I found this on Billboard.com: "For the past few decades, new album releases (and most commercially available singles) are released Tuesday each week in the U.S. Tuesday became the standard release day in April 1989, following discussions at the previous month's National Association of Recording Merchandisers (NARM) convention (March 3-7). Before then, Monday had long been the standard release day for new albums in the U.S."
