My group has a weekly game day on Friday evenings. However, because of scheduling conflicts and things that come up, we usually miss at least one week a month, and we've been going from end of November to mid January without a game.
I picked the closest approximation, which was twice monthly.
I don't have a regular group anymore. I've moved over an hour away, so it's not as easy to get together with them anymore, but we still sqeeze in a night every month to other month or so.
It's not nearly enough!!! At least I've gotten my fiancee to make her first steps into the RPG world with a playtest session of my homebrew and with some boardgames with RPG elements.
