The Cube Method. If you have a little bit of time on your hands, you can cut the stick(s) of butter into fourths and then cube into small pieces. The smaller the cubes, the quicker the butter will soften. Just leave them at room temperature for about an hour or until soft to the touch.
Ultimately, we can't tell you exactly how long you can leave butter out. We have no problem with leaving butter out to soften as long as it is well-covered. It usually doesn't take us more than a couple days to go through a stick anyway! We've never had rancid butter in that time.
