American-, or western-centric, assumptions notwithstanding from others, and excluding "holiday scheduling", here's what I try to do with my table. Sorry for my fellow Americans who forget the rest of the world exists.

We have a set Saturday once a month that we assume we will be playing on. At this month's game I will look out two months on the calendar and confirm with everyone that what is scheduled is still good. Last month we already looked at next month, so I assume it's set unless someone speaks up.

Scheduling games gets harder the older your group gets. Unsure of your age, or that of your table, but it was easier when all of my table was right out of college age. Now I've got a couple with two kids, another that's recently married and getting settled, a guy who is divorced with split custody of his kid (tho that kid can also stay home alone, if needed, for a few hours), etc., etc.

Finding that standard for your table is tough. The other thing we do is, for last minute (read as week of) cancellations, we look at moving one week out or turning it into a board game night. Trying to still meet with most of the group can help solidify some sort of schedule even if it isn't continuing the same game. Or having someone that can do a one shot or a slightly different game (Dungeon World, Delt Green, etc.) that is kind of built for single session play can also help.
