My life in weeks
Born May 14, 1990 · one row per year, birthday to birthday
The short answer
Your life in weeks is a chart with one box for every week: 52 boxes per row, one row per year of age. Ninety rows make 4,680 weeks. Someone who is 36 has filled in about 1,900 of them. Enter your birth date above to fill in yours and see how many weeks are still open to plan.
What is "your life in weeks"?
It is a chart of a whole life on one page. Each row is one year of age and has 52 boxes, one for each week. Ninety rows make 4,680 boxes. You fill in the weeks you have already lived, and the rest of the page shows the weeks ahead. Writer Tim Urban drew the original chart in 2014 in his post Your Life in Weeks on Wait But Why. This page makes your own version from your birth date.
The point is not the end of the grid. It is how many weeks are still open, and how much fits into one: a trip, a habit started, a call to a friend. People often use the chart to plan the next few months on purpose.
How the weeks are counted
| Number | How it is worked out | Example: born May 14, 1990 |
|---|---|---|
| Weeks lived | Days since your birth date, divided by 7, rounded down | 1,898 weeks (13,290 days) |
| Boxes filled | 52 boxes for each full year of age, plus the weeks since your last birthday | 1,892 boxes |
| Boxes on the grid | Years on the grid × 52 | 90 × 52 = 4,680 |
A year is 52 weeks and 1 or 2 days, so each row has 52 boxes and the extra days fold into the last box of the row. That is why the filled boxes come out a few lower than your exact weeks lived, about one box for every 5 to 6 years. Both numbers are right; they just count differently.
Life expectancy, honestly
The optional line uses US life expectancy at birth for 2024 from the CDC: 79.0 years for everyone, 76.5 for men and 81.4 for women (NCHS Data Brief 548). That is an average for babies born that year, not a prediction for any one person. The longer you have lived, the higher your own expected age: Americans who reached 65 in 2024 could expect 19.7 more years on average, to almost 85. Health, habits, income and luck all move the number. That is why the grid shows 90 rows by default, like the original chart, and the line is off unless you turn it on.
Ideas for the weeks ahead
- Color your chapters. School, cities, jobs, children. Seeing them as blocks helps you notice how long a chapter really lasted, and what you want the next one to hold.
- Count in seasons. If you see your parents twice a year, a page of weeks shows how many visits that is. Plan the next one.
- Pick one small habit. A week is long enough to start one: a daily walk, ten pages a night. The 100 day challenge is about 14 boxes on this grid.
- Make a list for this row. What would you like this year's 52 boxes to hold? A bucket list or a wheel of life helps you choose, and the year in review looks back on the last one.

Frequently asked questions
How many weeks are in a life?
A 90-year life is about 4,696 weeks: 90 years is 32,872 days, divided by 7. The chart rounds that to 52 boxes a row, 4,680 in all. At the 2024 US average life expectancy at birth, 79 years, it is about 4,120 weeks.
How many weeks have I lived?
Enter your birth date above. The tool divides the days since your birth by 7 and fills in the grid up to this week. It also shows your age, how many boxes are filled and when your next birthday is.
Who came up with the life in weeks chart?
Writer Tim Urban drew it in 2014 in the post Your Life in Weeks on his blog Wait But Why: 90 rows of 52 boxes, one box per week. This page lets you make your own version with your dates and colors.
What life expectancy should I use?
None, if you prefer: the line is off by default and the grid simply shows 90 years. If you turn it on, the options are the CDC's 2024 US averages at birth. They are averages for newborns, not a forecast for you; people who reach 65 live about 20 more years on average.
Why are the filled boxes a little fewer than my weeks lived?
Each row has exactly 52 boxes, but a year is 52 weeks and 1 or 2 days. The extra days fold into the last box of each row, so the grid falls about one box behind every 5 to 6 years. Your exact weeks lived is the big number at the top.
Can I print my life in weeks?
Yes, as a one-page poster on Letter or A4 paper in Classic, Soft dots or Ink saver. Print blank poster gives an empty grid to fill in by hand. Save phone wallpaper makes a phone-sized image with the top kept clear for the clock.
Is my birth date stored anywhere?
Only in this browser on this device, so the grid is ready next time. It is not sent to our server and there is no sign-up. Start over clears it.
