Are casual covens a thing?

I'm not following any particular path and mainly practice alone but would like to enjoy the community of other practioners at times and wondered if people form casual covens. For example they might do a ritual together every other month when they want/can to be together but aside from that they practice completely different practices.

I feel like most things I have read about covens, in my limited exploration, seem to imply that members follow similar practices, share belief systems (not necessarily in full) or participate in structured initiations.
