The year’s last sheet
December 2026 ends in ISO week 53, the highest week number anywhere in the run. A sheet that prints week numbers down the side of the grid has to be able to draw a fifty-third one, and this one does — the number is not clipped back to 52 to make the column tidy.
Twenty-three working days is the most any month of 2026 carries, shared with July, and eight days at the weekend is the fewest of any thirty-one-day month, again shared with July. The month opens on a Tuesday and closes on a Thursday, with Tuesday, Wednesday and Thursday each falling five times, and it holds in five rows on either grid.
Printing the twelve as a set
If the whole run is going up together, the sheets will not all come out at the same depth. On a Sunday-start grid, May and August need six rows and the other ten need five. On a Monday-start grid it is March, August and November that need six. August needs six either way, so there is no start day that makes all twelve match.
Whichever you choose, hold it across the run. Two sheets built on different start days put the weekend in different columns and will not read as a set on the wall.
Printing it
Print at 100% rather than fit-to-page. The PDF carries a real page box, so A4 comes off at 210 × 297 mm and Letter at 8.5 × 11 inches. Nothing is uploaded and nothing is kept: the file is written in the browser at the moment you ask for it.
