What this template is
This is the standard life calendar: one row for each year of age from 0 to 89 and one box for each of the 52 weeks in that year. Rows are grouped by decade with a little extra space, and every fifth year is numbered down the left edge so you can find your row without counting.
Ninety years is a deliberately generous span. In the current U.S. period life table, about three in ten newborn girls and one in five newborn boys would live to 90, so the bottom rows are a real possibility rather than a guarantee, which is the point of the exercise.
How to fill it in
Find your current age on the left and shade every complete row above it. In your current row, shade one box for each week since your last birthday, which is your age in days since that birthday divided by seven. If you would rather not count, enter your birth date on our home page and print the version that is already filled in.
A fine-tip pen works better than a highlighter for weeks you have lived; save colored pencils for chapters like school, cities, or jobs. Many people shade one box every Sunday evening as a weekly ritual.
Printing tips
Letter paper gives boxes about 2 mm across, small but fillable with a fine pen. Tabloid (11×17) roughly doubles the area and is the better choice for a wall. Set margins to default, scale to 100%, and turn off browser headers and footers.
