What is your favourite time of the day/night to work? When are you most productive?

I work better very early in the morning

After a cup of coffee!
It depends, best time to do small things, organise myself, read mails etc. is morning, before rest of my team start their work. But best time to go deep in work and focus is at night :) (not often but when i do, i can sit and work few hours straight)

I'm most productive when the kids aren't around :D, doesn't matter the time of day, but I do have a (bad) habit of staying up too late.
