actually I have a special day to play, but would be helpful in my case set days and times to be more comfortable and pleasant, but my schedule generally tend to be largely nocturnal .
As for me now I play more cash then tourneys. So for me nice time game is evening, when every players came from work or study and goes to the tables. But course I can play some (3-4 tables) during the business day, but almost all the tables seated by the NITs. But you always can play with strong hands=)
Good luck!
