The week after the holidays, I stood in my kitchen holding last year’s wall calendar. The pages were curled at the corners and covered in pen. The new calendar was still in its plastic wrap on the counter. Before I threw the old calendar away, I flipped through every month. I was surprised by how much of our family’s year was written on those pages.

That same week, I asked readers of this blog who still hang a paper calendar on the wall to tell me why. I expected to hear that it was just habit. The replies were more thoughtful than that. I read them at the kitchen table each night after my kids were in bed, and I started to notice patterns.

By the time the new calendar was hanging by the fridge, I had a list of ten things these readers, and our own family of my husband, my three kids, and me, seem to have in common. Here is what I noticed, told through the small moments of that week.

A wall calendar shows the whole month at once

During the week I swapped the old kitchen calendar for the new year’s calendar, our oldest asked me when the next dentist appointment was. I did not open my phone. I pointed at the wall. Our oldest walked over, found the square, and read it out loud. The whole month was right there, and the question took a few seconds to answer.

Patricia L., 63, of Des Moines, Iowa, wrote to me about this. Patricia said, “On my phone I only see today. On the wall I see the whole month, and I can tell when a week is getting too full before it happens.”

Seeing the full month in a single glance is the main reason most paper calendar people give for keeping paper on the wall.

Writing plans by hand helps them stay in memory

On the night I hung the new calendar, I sat at the kitchen table with a pen and copied in the birthdays, the school breaks, and the appointments I already knew about. It took a while. My husband asked why I did not just type them into a shared app. I told my husband that I remember things I write by hand.

When I was a teacher, I told my students to copy notes with a pen for the same reason. The act of writing slows you down, and slowing down helps things stick. I noticed this week that I knew the dates of the school break without looking, simply because I had written them out.

Writing plans by hand with a pen is slower than typing, and that slowness is the point for most paper calendar people.

The calendar hangs where the whole family walks past it

Our calendar hangs on the wall between the fridge and the coffee pot. During the week I was putting up the new year’s calendar, I paid attention to who looked at it. My husband checked it every morning while waiting for coffee. Our youngest stood on tiptoe to look at the pictures. My kids looked at it on the way to the snack cabinet.

Steve K., 47, of Tulsa, Oklahoma, told me his family’s calendar hangs next to the back door. Steve wrote, “Nobody in my house can say they did not know about something. It is right there every time anyone leaves.”

Paper calendar people put the calendar in a spot that gets walked past many times a day, not in a hallway or an office where nobody goes.

The phone is not the only copy of the schedule

On a weekday morning during the week I replaced our kitchen calendar, my husband’s phone would not turn on. The battery had died overnight, and the charger was in the car. My husband needed to know what time practice started for our oldest. I pointed at the wall, and the time was written in the square in my handwriting.

This happens more than I expected. Phones die, apps update, and reminders get swiped away. The paper on the wall does not need a password or a charge. Our family keeps the schedule on the phone too, but the wall copy is the backup that has not failed us yet.

Keeping a paper copy that does not depend on a battery is something nearly every paper calendar reader mentioned in their reply to me.

Small moments get written down next to the appointments

When I flipped through last year’s wall calendar before taking it down, I found more than appointments. In a square in March I had written “lost a tooth” for our youngest. In a square in July I had written “first time off the diving board” for our middle one. There was also a note about the day our oldest learned to ride a bike with no help.

Amanda G., 35, of Burlington, Vermont, described the same thing. Amanda wrote, “I write down when the kids said something funny or when we tried a new park. By December the calendar is a record of the year, and I did not have to try to make it that way.”

Paper calendar people tend to write the small family moments in the squares right next to the dentist and the oil change.

Crossing things out is part of the plan

During the week I was setting up the new kitchen calendar, a playdate for our youngest got canceled. I drew a line through the note with a pen and wrote it again on a different Saturday. The page looked a little messy. Nobody in our house minded.

I used to feel like a crossed out square meant I had planned badly. This year I am trying to see it differently. A messy calendar is a used calendar. Plans move. Kids get sick. My husband’s schedule shifts. The pen marks show that our family adjusted and kept going.

Paper calendar people are comfortable with scribbles and crossed out words, because a plan that changes is still a plan.

The week gets looked at before it starts

On the Sunday night of the week I hung the new calendar, my husband and I stood at the counter with our coffee and looked at the page together. My husband pointed at a late meeting on Wednesday. I pointed at a school event on Thursday. We figured out who was driving where and which night would be a simple dinner.

This took about as long as it takes to finish a cup of coffee. It saved us from the scramble that happens when a busy day surprises us. I noticed that several readers described the same Sunday habit, sometimes alone and sometimes with a spouse at the table.

Paper calendar people tend to look at the whole week before it begins, so the busy days are not a surprise on the morning they arrive.

A full page makes saying no easier

In the middle of the week I replaced our kitchen calendar, a friend called and asked if I could help with a project on Saturday. I walked to the wall while we were still on the phone. The Saturday square already had a birthday party for our youngest and a game for our oldest. I told my friend no, kindly, and offered a different week.

Ruth A., 70, of Mobile, Alabama, wrote to me about this exact thing. Ruth said, “When the squares are full, I can see it. I do not have to feel guilty. I just look at the page and say I am booked.”

Paper calendar people use the full squares as a plain, honest reason to say no without a long explanation.

The kids get to write on the calendar too

On the day I hung the new year’s calendar, our youngest asked for a marker and drew a star on a Saturday for a birthday party. Our oldest wrote the date of a school concert in careful letters. My kids now check the wall to see what is coming, and they push back less when a busy day arrives.

When I was teaching, I noticed that students who helped write the class schedule followed it better. The same thing is true at home. My kids feel like the plan belongs to them when their own handwriting is on it.

Paper calendar people often let every member of the household add to the page, even the ones who can barely hold a marker straight.

Old calendars get kept after the year ends

At the end of the week I swapped the kitchen calendar, I did not throw the old calendar away. I folded it flat and put it in the drawer with the calendars from the years before. My mom did the same thing when I was growing up, and I remember flipping through her old calendars on rainy afternoons.

Those old pages hold things I would not have remembered otherwise. The year our youngest was born is in that drawer. So is the year my husband and I bought our house. None of it is in an app anywhere.

Paper calendar people tend to keep the old calendars, because the written pages become a simple family record that costs nothing to store.

The new calendar is on the wall now, and the squares are already filling up with pen. I went into that week expecting to find that paper calendar people were just slow to change. What I found instead was a group of people, our family included, who like to see the whole month, write things by hand, and keep a record that does not depend on a battery.

I am not saying paper is better for everyone. My husband still keeps the work schedule on a phone, and that works for him. For our kitchen, and for the readers who wrote to me, the wall calendar is simply the thing that helps the most.

Do you still keep a paper calendar on the wall, and if so, where does it hang in your house?
