Almost every house has a job that has been put off, and most have several. That is not carelessness. It is what happens when three hundred small facts and dates live nowhere except somebody's memory.
The problem is that deferred maintenance does not stay the same price. Industry analysis puts the average deferred repair at over five thousand dollars by the time it is finally done, and every dollar of work put off can cost four or more later. The jobs below are the ones where that multiplier is real.
The jobs where delay actually costs
Intervals are typical rather than universal. Your manual wins over any table.

Why the reminder always arrives too late
Nobody forgets to service a boiler because they do not care. They forget because there is no natural moment to remember, and the reminder that finally arrives is a cold house or a stain on a ceiling.
The fix is not discipline. It is writing down when something was last done, so the next date is a fact rather than a guess.
What to record about anything in your house
Five fields, once, when you can actually see the appliance. This is the part that makes every future repair cheaper.

Seasonal jobs are not interval jobs
A good deal of outdoor maintenance belongs to a month rather than to a rolling interval. Blowing out an irrigation system belongs in autumn, not three hundred and sixty five days after you happened to write it down.
Treating everything as an interval is why generic maintenance apps end up telling people to winterise in July, and why they get ignored.
