Both of you thought the other had it. Nobody ever wrote it down anywhere you could both see, because it was understood, the way most of this is understood.
Or it's a medication dose neither of you is sure has already been given. A school form with a deadline only one of you knew about. An allergy detail a grandparent needed on Saturday afternoon but didn't have.
The problem doesn't have to be carelessness. It's that the information lived in one head, and the other person genuinely didn't know they were supposed to have it too. That isn't a character problem in either of you. It's a storage problem, and storage problems have fixes.
You've probably already tried something
A shared calendar. A wall display. A Notion page somebody built enthusiastically on a Sunday.
Setup goes fine. Maintenance is where it comes apart.
Go and read the customer reviews on the family calendar displays people spend two or three hundred euros on, and the same complaint keeps surfacing: months later, one person is still the only one opening it.
A better screen doesn't fix that. Build it alone, and it tends to stay yours alone, the same imbalance in a nicer interface.
The Household Wiki was built the other way round. The maintenance habit isn't advice sitting in a blog post you read once. It's the first thing in the file.
Six tabs. The first tab makes the rest work.
Open the file and you land on Home. Not an instructions page. A three-question check, about five minutes, once a week:
Did anything change this week that the other person needs to know?
Is anything expiring or coming up in the next 30 days that only one of us knows about?
Did we both open this file this week?
Standing Reference holds what rarely changes and is always needed at the worst possible moment. School hours, teacher, class, pickup time. GP, paediatrician and dentist with numbers. Medication with dose, frequency, and who gives it. Clothing and shoe sizes. Alarm code, boiler reset, bin days, building manager. Vet and feeding routine if there's a pet.
Calendar Spine doesn't replace Google Calendar and doesn't try to. It's the written record of your recurring commitments with a Coverage Owner column, so the answer to "who's got Thursday" is already on the page before anyone has to ask.
Handover Checklist is what you fill in before you travel or work late. Dates, medications due and exact instructions, pickups during the absence, anything unusual, and when to call you versus when to just handle it. About five minutes before you leave, so whoever's covering isn't left guessing, whether that's your partner, a grandparent, or a sitter.
Gift & Occasion Log is the small one. What you gave, to whom, when, roughly what it cost, and what's coming in the next 90 days.
At the end of the spreadsheet, you'll find the Instructions tab. It's a two-minute read on how to share the file, how to pin it to a phone home screen, and where to start.
Every tab arrives with example rows already filled in, shaded and italic, so you're not staring at an empty grid working out what belongs where. Overwrite them as you go.
"If you had to text your partner to ask for this information, it belongs here."

Fair questions
Do we need Notion, an app, or an account?
Excel or Google Sheets, not Notion. Most people already have one. If you don't, Google Sheets is free and takes about two minutes to set up.
What makes this stick when the last thing didn't?
Honestly, nothing guarantees it. What's different is that the weekly check and the change log live inside the file itself, not in a separate document you have to remember exists. It's the first tab, always one click away.
Does this replace our calendar app?
No, and you shouldn't want it to. Calendar apps are good at reminding you about Thursday. They're bad at holding the alarm code and the dosage. Keep both.
Can we both edit it at once?
Yes, if you put it in Google Sheets and share it with Editor access. Tab 6 walks through it in two minutes.
There are free household templates everywhere. Why €19?
Free templates give you a grid. Filling it in was never the hard part, keeping both of you using it is. That's the part the €19 buys, the built-in weekly check that free templates don't have.
One thing worth saying plainly
This is new. There are no testimonials on this page because nobody has had six months with it yet, and inventing some would be a strange way to start.
I'm also a man building a tool for a problem the research consistently shows falls harder on women, and that's worth stating rather than writing around. The wiki doesn't take a position on whose fault anything is. It just moves what's in one head onto a page both of you can reach.
What I can offer instead of a wall of reviews: seven days to get your money back, and a file you can judge properly in ten minutes.
One place for the information both of you need
Not another calendar app. Not a template you fill in once and forget. The reference both of you keep current, because keeping it current is built into the thing.

Not ready?
Take the Standing Reference tab on its own, free. It's the single most useful tab in the file and it'll tell you in about ten minutes whether this way of working suits your household.
