Does anybody really care? I know I don't. In the summer, I shower in the morning, without a doubt. In the winter, I often bathe at night, a hot bubble bath to soothe, relax and definitely delay getting up in the morning when I can capture a few more minutes of sweet, slumber. Sure, I shake it up a bit once in a while but generally this is my pattern. As long as you are clean, feel clean, smell clean, do whatever you want to make you happy.
