How to Keep Track of the Chores That Don't Happen Every Day
Some chores recur every few weeks or months on no fixed schedule, which is exactly why to-do lists and calendars lose them. Track the interval instead.
By Mar San Agustin
The short answer
Irregular chores slip because to-do apps want a due date and calendars want a fixed recurrence, and these tasks genuinely have neither. Guess too tight and you snooze the reminder into meaninglessness; guess too loose and you forget it exists. The fix is to stop scheduling them and start recording them: log the chore when you do it, and read how long it has been whenever you wonder. That turns a memory problem into a lookup, and it is always honest.
Some tasks are easy to remember: they happen every day, or they're on a calendar with a due date. Then there's the other category: the stuff that needs doing every few weeks or months, on no fixed schedule, that quietly falls off your radar until something breaks or someone notices.
When did I last change the water filter? Has it really been that long since I called Mom? When did the car last get an oil change?
If you've ever caught yourself asking one of those questions with no real answer, you've met the "when did I last...?" problem. It's not a memory failure. It's a tooling failure.
Why to-do lists and calendars don't fix this
To-do apps want a due date. Calendars want a fixed recurrence. Both force you to guess at a schedule for something that doesn't really have one. Set the reminder too tight and you'll snooze it into meaninglessness. Set it too loose and you'll forget it exists between pings.
Notebooks and spreadsheets have the opposite problem: no friction to write it down, but also no friction-free way to check it later, and nothing reminds you a spreadsheet exists.
This is the same mismatch that makes daily streaks backfire: the tool insists on a cadence the task never had.
What actually works is a system built around one question: when did I last do this, and how long has it been? Not a due date. Not a checkbox. Just an honest, always-current answer.
The chores worth tracking this way
Almost anything that recurs without a fixed calendar date fits:
- Home maintenance: water filter changes, HVAC filters, gutter cleaning, smoke detector batteries
- Vehicle care: oil changes, tire rotations, wiper blades
- Health & self-care: dentist visits, skin checks, stretching, medication refills
- Relationships: calling a parent, checking in on a friend who's been quiet
- Digital & financial: rotating passwords, reviewing subscriptions, backing up photos
Starter list: if you're not sure where to begin, pick the three things that have caused you the most annoyance when forgotten. A burst pipe from a filter you didn't know was overdue counts. Track those first. Add more once the habit sticks.
Reduce the friction, or it won't last
The system only works if logging is easier than not logging. A few things that help:
- Name things specifically. "Change HVAC filter" beats "house stuff": vague entries are the ones you stop checking.
- Log from where the chore happens, not from an app you have to remember to open. A home-screen widget you tap once, or a Siri command you say out loud while your hands are full, beats hunting for an icon. TimeSince also supports pairing a cheap NFC sticker with a chore: stick one on the actual water filter, and tapping your phone against it logs the change on the spot, no app-opening required.
- Don't over-track. A list of 40 chores you never check is worse than a list of 5 you actually look at. Start small.
- Let intervals replace guilt. The point isn't to hit some ideal cadence. It's to finally have an honest answer when you ask "when did I last do this?" Sometimes that answer is "longer than I thought," and that's exactly the information you were missing.
Once you stop trying to force irregular chores into a daily-streak or fixed-calendar shape, the whole category gets a lot less stressful to manage. You just check the number, and you know.
Frequently asked questions
Why don't reminders work for irregular chores?+
A reminder needs a date you do not actually have. Set it too often and you start dismissing it on autopilot; set it too rarely and the chore is overdue before it fires. Recording when you last did it sidesteps the guess entirely.
How many chores should I track?+
Start with three: the ones that have cost you the most when forgotten. A list of forty entries you never open is worse than five you actually check. Add more once checking the list is a habit of its own.
What is the easiest way to log a chore?+
Whatever takes the fewest steps at the moment it happens. A home-screen widget you tap once, a Siri command you say with your hands full, or an NFC sticker on the filter itself all beat unlocking your phone and hunting for an app.
