My meets have tended to be spread evenly across every day of the week. Club meets might be more likely on a Friday or Saturday but everything else is fair game for any day.
That is tricky, Saturdays most people are free but then you are competing with everyone else.
Monday there is the least amount of competition but the least amount of "being arsed".
I used to meet weekday evenings or weekday daytimes for socials. Not very often at the weekends.
Alot of people no longer work 9-5 so have different shift patterns
