Color One Square Each Week and Watch 80 Years Fill with Your Story

Weeks in a relationship or life blur together. You remember birthdays and trips, but the quiet in‑between time mostly stays invisible. We track deadlines and appointments on digital calendars, but rarely see the whole arc of a shared life at once, the years you’ve already moved through and the ones still sitting empty ahead. There’s something oddly powerful about seeing every week you have, and have had, laid out in one place on a wall.

NOS Calendar by Som by Mos is a weekly calendar that celebrates shared life rather than meetings or deadlines. Each square is a week, each row is a year, and each block is a decade, printed on a 50cm x 70cm poster that covers more than 80 years. It’s sold under the tagline “our time is limited, shall we share it?”, which is a very different brief from “get more done” or “optimize your schedule.”

The image of a couple or close friends unrolling a poster, finding the week their story began, and coloring that first square sounds a little romantic. Every week after that, they fill in another box, sometimes with a simple color, sometimes with a shade that matches a key moment like a trip or a move. The act is small, a few seconds with a pen, but it becomes a quiet check‑in on how time is passing together rather than just another task.

The grid works simply enough. You’ve got 52 columns for weeks, rows for years, and decade blocks that make long stretches of time visible. A strip at the bottom acts as a legend, where you assign colors to things that matter: trips, moves, new jobs, losses, whatever you decide. Over time, the poster becomes a code only you understand, a visual index of your shared history that nobody else can read.

Seeing 80 years of weeks on a wall changes your sense of scale. The empty squares make future time feel both generous and finite, while the filled ones remind you that a lot has already happened. It’s less about planning the next week and more about noticing that this one exists, that you’re somewhere in the middle of a grid that’ll eventually be full whether you pay attention to it or not.

Of course, the minimalist design matters. The clean grid, the simple headings like “Journey of our life together” in English, Spanish, or Catalan, and the durable paper meant to last decades in a frame all keep it neutral. Your colors and notes do the talking, which makes it easier to hang in a living room without it screaming “productivity chart” at everyone who walks by.

NOS sits somewhere between art, journal, and commitment device. It doesn’t tell you how to spend your weeks; it just refuses to let them stay invisible. The idea of tracking life without another app or notification, just a poster that slowly fills with color as you move through years together, is a surprisingly gentle way to remember that time is limited, and that you chose to share it with someone worth coloring squares for.
