how would you like your time system to work?

1 day = 1 month ingame
1 day = 3 months ingame
2 days = 3 months
3 days = 3 months
3 days = 6 months
7 days = 6 months

i understand everyone has a life out side, hence this question, i would prefer a 3 day barrier between the months but its up to you guys really.
