Q.
The scheduled time for an event has already passed, but it still remains on the list.
Event Participation & Meetup Rules
Yes, that is correct. To allow you to check the history of meetups that have already concluded this month and evaluate the manners of the neighbors who participated with you, regular meetups remain visible on the list until the 'last day of the given month', and casual impromptu meetups remain visible until 'midnight (24:00) today'. They are automatically removed from the list after the specified period.
