If you live in an area with a craft brewery scene, ask them about which night of the week is slowest. Offer to host an event... trivia, board games, a hobby meet up, whatever you are interested in... you can even make it a destination for a running or biking club... on that night. They'll usually be happy to advertise it in order to get a few more people in on the "dead" night and you'll have a regular place to go to indulge something you enjoy while meeting new people.

I've done this twice at two different breweries and at this point the groups are self-sustaining with Facebook & Discord groups managed by other group members.
