After working straight through the evening it is the hour when you realize that you've worked all the way through the night, and the sun is about to rise.

This most often happens with design, development or other types of work when it's easy to lose time while focused on the task at hand.
I really got in a zone working on the design comp for the new project. I started around 3p and worked until WTF o'clock.
