Medieval serfs typically worked about 150 10 hour days a year.
In addition to the winter months there's a lot of gaps where the plants are in the ground, and now just need intermittent maintenance.
All of this of course ignores women's work, which was more omnipresent across the year. But it was also pretty social as well, hence the lasting power of phrases like "sewing circles".
FWIW: That 150 hour estimate came from work by Gregory Clark at UC Davis who has since cast doubt on it.
“There’s a reasonable controversy going on in medieval economic history,” Clark told (Amanda Mill). He now thinks that English peasants in the late Middle Ages may have worked closer to 300 days a year.
