About Life in Weeks
Life in weeks is a simple and beautiful idea: draw one small box for every week of a life. One row is one year, with 52 boxes. Ninety rows make 4,680 boxes — a whole life fits on one sheet of paper.
Enter your birth date, and this tool fills in every week you have already lived and marks this week. Add the dates that matter to you — school years, a first job, a move, a wedding, a long trip — and they get their own colour. Then save it as a poster to print, or as a wallpaper for your phone.
People hang it above their desk, share it with friends, or give it as a gift. Many say it helps them see how much they have already done — and how many good weeks are still ahead to plan.

How the weeks are counted
A year is 52 weeks and one more day (two in a leap year). So "one box per week" needs a clear rule. This tool uses the rule that keeps every row in step with your birthdays:
- Each row is one year of your life, from one birthday to the next
- The row is cut into 52 boxes of 7 days, counted from that birthday
- The 52nd box runs until the next birthday, so it holds 8 days (9 when a February 29 falls in it)
- If you were born on February 29, your birthday is February 28 in other years
So the poster always has exactly years × 52 boxes, and every row starts on a birthday. "Weeks lived" is the number of filled boxes. The real number of 7-day weeks since your birth is a little higher — about one more week every 5.6 years. The tool shows both.
| Age | Boxes filled on that birthday | Days lived (born March 12, 1990) | Full 7-day weeks |
|---|---|---|---|
| 10 | 520 | 3,653 | 521 |
| 20 | 1,040 | 7,305 | 1,043 |
| 30 | 1,560 | 10,958 | 1,565 |
| 40 | 2,080 | 14,610 | 2,087 |
| 50 | 2,600 | 18,263 | 2,609 |
| 60 | 3,120 | 21,915 | 3,130 |
Worked example: someone born on March 12, 1990 is 36 years old on November 13, 2026. Their last birthday was 246 days ago, which is box 36 of that row (246 ÷ 7 = 35 full weeks). So 36 × 52 + 35 = 1,907 boxes are filled. They have lived 13,395 days, which is 1,913 full weeks of 7 days.
Sizes

| Phone wallpaper | 1170 × 2532 px | — |
For a big print, use the PDF: it is drawn with lines, not pixels, so the boxes stay crisp. A print shop can print the 18 × 24 in PDF as it is. The phone wallpaper leaves the top quarter free, so your lock-screen clock does not cover the boxes. It fits most phones; the phone crops the sides a little if its screen is wider.
The number of years on the poster only sets its length — 70, 80, 90 or 100 rows. With 90 years there are 4,680 boxes; with 100 years, 5,200.
Eight styles
- Classic — black boxes on white, this week in red
- Minimal print — light grey, thin lines; saves ink
- Dark — light boxes on deep navy, this week in gold; great as a wallpaper
- Pastel — soft colours that change every decade, on cream paper
- Rainbow decades — each decade of your life in its own bright colour
- Blueprint — white boxes on blue, in a typewriter font
- Vintage — brown ink on old paper, in a serif font
- Sunset — your years go from gold to orange, pink and purple
The style only changes the colours and the font. The boxes, labels and milestones are the same in all of them.
Ideas for milestones
- School and study — from your first school day to graduation, as one coloured span
- Places you lived — each city or home as its own span
- Big days — a wedding, a child's birth, a first job, a first marathon
- Plans — a trip next summer, a sabbatical, a house you want to build. A milestone can be in the future: it shows in its colour on the empty boxes ahead
- A gift — make a poster for a parent's or a friend's birthday with the moments you shared
Frequently asked questions
How many weeks are in a life of 90 years?
On this poster, 90 × 52 = 4,680 boxes. Counted in exact 7-day weeks, 90 years are about 4,696 weeks, because every year has one or two days more than 52 weeks.
How many weeks have I lived?
Enter your birth date. The tool shows the number of boxes filled on the poster, the days you have lived, and the number of full 7-day weeks. All three use today's date on your device.
Why is "weeks lived" a bit lower than days ÷ 7?
Because the poster starts every row on your birthday and gives each year exactly 52 boxes. The one or two extra days of each year go into the last box of the row instead of making a new box. Days ÷ 7 counts those extra days as weeks, so it grows a little faster.
What does "Years on the poster" mean?
It is only the length of the poster: how many rows it has. Pick 90 for the classic look, or 100 if you want more room. It is not a prediction of anything.
Can I make one for someone else?
Yes. Type their birth date and a title like "Grandma's life in weeks", add the moments you shared as milestones, and print the PDF. It makes a personal gift.
Can I add a milestone in the future?
Yes. A future date is drawn in its colour on the empty boxes, so you can see a planned trip or a goal on your timeline.
Is my birth date sent anywhere?
No. Everything is drawn in your browser. Your birth date, title and milestones are saved only on this device so the poster is still here next time.
