I'm looking for a noun which roughly means "the little chores" in life, something similar to mundane tasks (such as fetching groceries, doing the laundry, etc), but a bit more generic than "errand". Preferably something that implies that the action could be repeated.
A daily routine suggests a a series of ordinary repeated actions: (from TFD)
A set of customary or unchanging and often mechanically performed activities or procedures:
- a routine of housework.
Consider the daily round:
the tasks you have to do every day:
I get exhausted just by the daily round.
(Definition and example from Cambridge Dictionaries Online.)
Everyday tasks and daily to-do list are further possibilities.
