Our default schedule is every other Saturday evening. However, at the end of each session we review the calendar. If anybody can't make it to the next session, we discuss alternatives (move it to Friday? a different weekend? what if we do it at a different location?) to see if there's a way to make it work for everyone. If there is, we go with that; if there isn't, we stick with the regular schedule and whoever can't make it, can't make it.
Around the Christmas holidays, everyone's schedule goes crazy and we just jam in games wherever they fit.
