The almanacs mean that the sun is completely below the horizon. You'll have a few minutes left of sunlight before it's gone.
I've scheduled our wedding for 4.30 which means by 5, when we'll be taking the pictures, you'll get a good sun through the clouds glow. Or at least, that's what I've been told. I've spoken to three photographers and was told that you want the day to have broken to get some great pics of the sky. In the day it'll be too bright and at night just dark.
