Why keep a headache diary?

Patterns — sleep, food, stress, the time of month — show up over a few weeks, and your doctor can see how often and how strong the headaches are.

What should I write down?

Date and time, strength from 1 to 10, how long it lasted, possible triggers, the medicine taken and whether it helped.

Can I change the columns?

Yes — each line of the columns box is a column; add aura, nausea or anything else.

Is it a medical tool?

No — it is a log to fill in; your doctor reads it with you.

How many rows fit on one page?

With the Notes for my doctor box, up to 27 rows on the landscape Letter sheet it starts as (the default is 20) and up to 40 in portrait; without the box, 31 and 44. Past that the table runs on to a second page, with the headings repeated.

Can the dates fill themselves in?

Yes. Fill the first column with “Dates, one per row” from the day you choose, or with “The days of one month”, the 1st to the last. They print US style with the weekday, as Sun, 11/1.

Is anything uploaded?

No. The pages are made in your browser.

Example

Example: all of November on one sheet, a row per day, with an aura column

Someone with migraines wants a full month on paper for a doctor’s appointment, a line for every day whether there was a headache or not. They start from this diary and change three things: Fill the first column with “The days of one month”, starting 2026-11-01; Direction Portrait; and one more column, Aura*, typed at the end of the columns box.

The first column fills itself in, one row a day: Sun, 11/1, Mon, 11/2 … Mon, 11/30. A month gets as many rows as it has days, 30 here, whatever the Rows box says.
A column heading ending in * prints a tick box in every row instead of space to write, so Aura becomes a column of small squares.
In portrait the 30 rows are about 6.4 mm (¼ in) high and the Notes for my doctor box still fits under them: one Letter sheet. In landscape, the default, the same month would run onto a second page.

headache-diary.pdf, one portrait Letter page: the heading, Name and Month lines, 30 dated rows with every other row shaded, and the Notes for my doctor box. On the free plan a small line with our name is printed at the foot. It is a log to bring along; what it means is for the doctor.

How it works

Print the diary and keep it with your medicine.
Write down every headache: when, how strong, how long, and what may have caused it.
Bring the pages to your doctor; change the columns if you need others.
