Daily planner

The sheet on this page is titled Daily planner, 07:00 to 21:00. It is a single sheet, drawn on A4 at 595.28 by 841.89 points, and it prints 15 time rows down the page: 07:00, 08:00, 09:00, and so on to 21:00 at the foot. The file is written by this site while the controls are set, and the version described here comes out at 2,748 bytes.

The range includes both ends

07:00 to 21:00 means a row at 07:00, a row at 21:00, and every hour in between. The 21:00 row is a row like the others, with the same depth and the same space to write in. This is the decision a paper diary makes, and it is worth stating because the other reading is the one arithmetic falls into: treat the range as the distance between its two ends, and the last hour is never printed at all. The count here is 15 rows with both ends present.

Twelve-hour and twenty-four-hour labels

Both clocks are offered, and the setting shown above is the twenty-four-hour one, which is why the labels read 07:00 and 21:00. On the twelve-hour clock the same rows carry AM and PM, and midnight and noon are both written 12, never 0. A sheet that prints 0:00 AM has been labelled by dividing the hour and taking the remainder, without anyone looking at the paper afterwards.

The time column is sized to the widest label

The column that holds the times is measured against every label the sheet will print, not against the first one. On the twelve-hour clock 12:30 PM is wider than 1:00 AM, and it is not the first label down the page, so a column sized by the first label would be too narrow and the widest times would be clipped. Measuring the whole set costs nothing and is the only version that holds for every combination of start, end and step.

Half hours and quarter hours

The step can be an hour, a half hour or a quarter hour. Finer steps mean more rows on the same paper and therefore shallower rows, so the two settings work against each other. Where the rows would come out too shallow to write a word in, the sheet is refused rather than drawn, on the grounds that a form that looks correct on a screen and cannot be used with a pen is worse than no form. nine points, a little over 3.17 millimetres, which is about the floor for a handwritten word

Black only

Everything on the sheet prints in black. No part of its meaning is carried by colour, so nothing is lost on a mono printer, on a printer low on one cartridge, or on a photocopy of a photocopy. A ruled line is a ruled line whatever the machine is doing.

A set of seven

The same planner can be printed as a set of seven, one sheet per day, each headed with its own day name. The times, the clock and the step stay as they are set; only the heading changes from sheet to sheet.

What is actually on it

At this setting the sheet carries 19 ruled lines and 16 words of printed text. There are no boxes and no squares on it. Nothing here is a hosted template or a file licensed from anyone: the geometry is written out by the site as a PDF, byte by byte, when the download is asked for.
