Life in Weeks

The idea

A typical human life of 80 years is a little over 4,000 weeks; that is a surprisingly small number when you can see it all at once. Laying every week out on a single grid turns an abstract span of time into something concrete you can look at, which is why this visualisation is often used as a gentle prompt to think about how the weeks are spent.

Reading the grid

• The grid has 52 columns, one for each week of the year.
• Each row is a single year of your life, starting from birth at the top.
• Filled squares are weeks you have already lived.
• Empty squares are the weeks that may still lie ahead, up to your chosen life expectancy.
• The square with a highlighted outline is the week you are living right now.

Life stages

When "Colour by life stage" is enabled, lived weeks are shaded according to a rough stage of life; these boundaries are only a common convention and are not meant to be precise.

• Childhood: ages 0–11
• Adolescence: ages 12–17
• Young Adulthood: ages 18–29
• Adulthood: ages 30–44
• Middle Age: ages 45–64
• Senior Years: ages 65 and up

Notes

• Weeks are counted from your exact date of birth; a year is treated as 52 weeks for the grid, so the visual is a close approximation rather than a calendar-exact count.
• Life expectancy is a personal setting; adjust it to whatever figure feels meaningful to you.
• Everything runs entirely in your browser; your birthdate is never sent anywhere.
