@rixx just create a new calendar for chores, if they happen a couple of times per year it's easy to fill out by hand. But if you can make it somewhat regular, maybe a script can fill in the calendar with your chores

@vague It’s the "repeat after completion" bit that is hard to do with calendars alone.

@vague If I have a monthly task that I put off for two weeks (and no, that’s not necessarily “motivation”. I may not be home, I may be ill, etc), then I don’t need it to occur again after two weeks, I need to occur it at four weeks after completion.
