I'm never up early enough to play in the mornings, haha! xD I tend to stay on from late afternoons to the evening, and sometimes late at night when I'm bored.
I don't have time in the mornings since I have class everyday during the week, then I don't like playing when the shops are closed so I'm an afternoon player. Usually at around 3-5 everyday during the week.
Then on weekends I'll usually play around noon if I'm not busy.
I usually play at night since I'm so busy during the daytime. I also really like the peaceful night music. ...Although, I have the beautiful town ordinance so the stores are always closed, but I don't feel like changing it/changing the clock, haha
I play whenever I have time to sit down and properly concentrate, usually the afternoon but depends on shifts. I don't really like playing in the evenings unless I'm wifi-ing with friends. Weekends and holidays and stuff then anytime is fair game
I work from home atm so whenever I have time and feel like it. If I have to choose I prefer playing during the morning, I have stuff to do around the house, especially during the evening.
I play whenever I have time. Usually, I'll start playing at around 11AM because I'm disabled and can't drive anywhere, so I get bored a lot, especially once all the cleaning is done. Then I'll log back on at around 8 or 9 PM, so I can go beetle hunting and get the nighttime catches.
