Today is April 23/30 on your calendar. In printing parlance this is called a hanging date, which does not have anything to do with capital punishment. It happens when a month starts on a Friday or Saturday and rolls over into a sixth week. Apparantly it's acceptable to use a hanging date on only a Sunday or Monday.
I always called a day like today a "slash day" so in honor of that here's Slash playing one of the great riffs of all time.
