It varied wildly, but a good portion probably didn’t truly “own” their land, so the workdays they owed to the landowner were most likely their debt for the “privilege” of being able to live and work the land the rest of the time. In some instances though I imagine they were probably paid for harvests, then owed a certain amount of that to the landowner. Everything was pretty much local, so they would’ve had weekly markets where they traded whatever excess stuff they had for coin.

Given all the extra work they had to do for just regular things we don’t even think about, it’s hard to even compare peasant workdays to modern workdays. Yes, we spend more time in our workplaces, but we also don’t spend additional hours of manual labor on hunting, scavenging, collecting, or cutting down wood for having to cook our food or heat our homes. It’s kind of hard to compare the two lifestyles.
