Friday night > Saturday afternoon/evening > Thursday night > Sunday lunchtime through to early evening

For me it's as above ^. Friday night it's straight after work - not bothering to go home first. Then the next preferable is Saturday afternoon - say, about 4:30pm to about 5pm, then home by about 10.
During the week; on a Thursday is my next favourite....because you've only got one more day to work. Then Sunday starting at around lunchtime and finishing at about 5 or 6 would be my next fav. The only thing I don't like about drinking on a Sunday, is that the day seems to go so quickly.

You?
