A life on one page
Drawn as weeks, a whole life fits on a single page. Ninety years is 4,680 boxes, few enough to count and small enough to see at a glance. The idea has been popular for years because it changes how a week feels: once you see that each box is one of a limited number, a free Saturday or a week of holiday looks more valuable, and a wasted week looks more expensive. The grid above draws yours, with the weeks you have already lived coloured by stage of life.
Most people are struck by two things. The first is how much of the grid school takes up, about thirteen rows of green. The second is how many empty boxes are still ahead, even for people well into middle age. Both are reasons to think about how to fill the next row.
How we calculate it
Each row is one year of your life, starting on your birthday. We count the days since your last birthday and divide by seven to find which box you are in now; the 52nd box of each row holds the one or two extra days a year has beyond 52 weeks. The headline figure is the exact number of whole weeks since you were born, which runs a little ahead of the box count because of those extra days.
| Grid to age | Boxes | Real weeks |
|---|---|---|
| 70 | 3,640 | about 3,652 |
| 80 | 4,160 | about 4,174 |
| 90 | 4,680 | about 4,696 |
| 100 | 5,200 | about 5,218 |
Worked example. Someone born on 12 April 1990 has lived 13,350 days by 30 October 2026, which is 1,907 whole weeks. On the grid they are in box 29 of row 37, the row for age 36, and 2,789 weeks remain before their 90th birthday, so the grid to 90 is about 41% filled.
What people do with it
Some print the grid and colour in a box each Sunday. Others mark the weeks of big events: a move, a new job, the birth of a child. Seen this way, the rows that hold real change stand out, and it becomes easier to decide what the next one should hold.
Questions people ask
Why does each row have 52 boxes when a year has a little more than 52 weeks?
A year is 52 weeks and one or two days. To keep every row lined up with a birthday, each row starts again on your birthday, so the last box of each row holds those extra days. That is why the box count and the exact number of weeks you have lived differ by a few.
What does the age I choose do?
It sets how many rows the grid has. It is simply the age you want to see the grid up to, not a forecast.
What do the colours mean?
Weeks already lived are coloured by stage of life: early childhood, school years, young adult years, working years and the years after 65. The coral box is this week. Empty boxes are the weeks still ahead.
Can I see the dates for a box?
Yes. Tap or click any box and the panel below the grid shows the dates that week covers and how old you were or will be.
