No. Monday is often the popular day of the week chosen by venues as it is often their quietest day after a busy weekend.
It can often be the loneliest day of the week for some, too, so an ideal day to seek some company.
Some businesses find that other days of the week are better suited to run their sessions on, and the network caters for any day of the week – we have MeetUpMondays on Tuesdays, Wednesdays and Thursdays too!
So check which day of the week your local venue runs their sessions on before going along.
