It Spells the Month. It Cannot Count the Days.

A Flawless Dog, Sitting Above a Week With Ten Days In It

Start with this one, because it is the whole page in a single image. The photograph is genuinely good — a golden retriever head on in summer grass, two eyes level with each other, one nose, two ears, clean summer light, exactly the picture somebody would want on their July page. The word JULY is spelled correctly. Now read the grid underneath. The instruction was seven columns headed M T W T F S S; what came back has ten columns, headed M W T T F S S S, with the Tuesday missing and three separate Saturdays and Sundays tacked onto the right. Follow the numerals and the second row runs 7, 8, 9, 10, 11, 12, 14 — the 13th of July does not exist on this calendar. The third row contains a 29 sitting between an 18 and a 21, and a 31 that then turns up again four cells later. Everything a camera would have captured is right. Everything that had to be counted is wrong.

The Nicest Design Here, and It Contains a 37th of March

As a piece of design this is the best thing the tool produced. Cream card hanging flat against a warm white wall, one sage green single-line mountain range with the kind of restraint a human designer would charge for, MARCH set in clean black capitals underneath, hairline grid below. It is a print-shop product. Then enlarge the grid. There are eight day columns instead of seven, headed M T W T T F S S, with Thursday appearing twice and Wednesday appearing once. The first row skips the 3rd and the 6th. The second row runs 8, 9, 7, 8, 10 — going backwards into numbers the row above already used. And in the fourth row, two cells from the right, there is a 37. Not a badly drawn 31, not a smudged 27: a clean, crisp, correctly kerned 37, on a month that has 31 days. The artwork is worth keeping. The dates are decoration.

The Closest to Correct: Seven Real Columns, and Still No 3rd or 10th

This is the one you would ship, and it is worth being precise about why. It is the only render of the six that got the week right: seven columns, headed M T W T F S S, in the correct order, no duplicates, no extras. The card is a clean piece of bold modern layout — heavy black OCTOBER across the top, one thick orange rule under it, grid filling the rest, standing on a wire easel with a soft shadow. Even the styling decision is sensible: it tinted a column orange to mark the weekend. It tinted the leftmost one, which is Monday. And in the grid, the first row ends 1, 2, 4 and the second row runs 5, 6, 7, 8, 9, 11, so the 3rd and the 10th of October are simply absent, while the 11th is printed twice in two different rows. Seven correct columns out of six attempts, and it still loses two days out of a month.

September Given Thirty-One Days, Twice

The classroom styling is exactly right for the brief: a cheerful border of flat vector suns and red apples across the top, SEPTEMBER in chunky rounded blue capitals, and date cells as soft rounded squares alternating yellow and blue, which is precisely how an infant classroom wall calendar looks. It is also the render that fails hardest on arithmetic. September has thirty days. This one ends on a 31 in the fourth row, and then a second 31 sits alone in a fifth row underneath it — the same non-existent date, printed twice, on the poster most likely to be pinned up in front of children learning what dates are. There are eight columns rather than seven. The second row reads 5, 8, 9, 9, 11, 12, 10. The teacher-facing lesson is the same as everywhere else on this page: keep the border, keep the typography, and put the real month grid in yourself.

Seven Correct Columns, and the 31st Arrives Before the 29th

The painting is lovely and reproducible: loose watercolour peonies with soft bleeding edges on textured cream, MAY in a delicate serif, fine grey hairline grid. This is the second of two renders that got the week structure right — seven columns, M T W T F S S, correctly ordered. The dates are the usual story with an interesting twist. The first row reads 1, 2, 3, 6, 7, 6, 7: the 4th and 5th vanish, and the 6th and 7th are each printed twice inside a single week. In the third row a 25 sits next to another 25, and the row finishes on the 31st — after which a fourth row begins with 29 and 30. The month ends, then carries on for two more days. Note what stayed reliable across all six images though: the month name. MARCH, JULY, MAY, SEPTEMBER, OCTOBER, AUGUST, every one of them spelled correctly on the first attempt.

It Invented a Weekday Order, and Then a Date Called Zero

The retro print job is excellent — mustard, burnt orange and brown sunburst over rolling hills, offset grain in the ink, AUGUST in a fat rounded seventies display face, brown numerals on cream. If you were selling a risograph calendar, this is the top half of it. The bottom half invents things. The column headings read M T T W T F S S: eight columns, and the week itself reordered, with Wednesday demoted to fourth place behind two Tuesdays. The second numbered row runs 8, 9, 0, 7 — a zero, printed as a date, in a grid where zero cannot occur. The month stops at 30, so the 31st of August never happens, and the 21st appears in two different rows. Three separate failure modes in one card: a wrong week, an impossible numeral, and a missing day.
