How to print it
Choose Paper for a home printer: dark ink on a light sheet, nothing wasted on the background. Letter and A4 print at 300 dpi on any office printer. For 18×24, download the PNG and take it to a print shop; it's sized at 150 dpi, which is plenty for a poster you look at from across the room.
Each row is one year of your life, 52 weeks across. Every tenth row is labelled. The filled dots are the weeks behind you, the amber one is this week, and the empty ones are still yours. Many people fill in one dot every Sunday with a pen.
