It depends. I usually almost always smoke at night because its more convienient. But smoking in the day is a lot of fun too. Especially if its a cloudy or rainy day and you can really just relax. If I had my own place I would probably spark up earlier in the day than i currently do. I normally don't light up until around 11 pm or later. If I had an apartment or a house or some place of my own id probably toke up around 7 pm. Any time is smokin time really.
