Year in Pixels

A year in pixels is the whole year on one grid: twelve columns for the months, thirty-one rows for the days. Tap a day, pick one of five moods, and the square takes its colour. Rename the moods and change the colours, then print the sheet blank or filled, or save your year as an image.

How the grid is built

The grid is twelve columns, one per month, and thirty-one rows, one per date, which makes 372 squares for a year of 365 days. The squares a month does not have are left empty rather than squeezed out, so every row stays one date wide: February loses three (two in a leap year), and April, June, September and November lose one each. That leaves seven empty squares in a common year and six in a leap year. The length of each month comes from the calendar rather than from a table, so the leap rule is applied in full — divisible by four, except centuries, except centuries divisible by four hundred.

Today is the last day you can colour. Later days are locked, because a mood is recorded after the day rather than planned before it. The count above the grid is the days you have coloured against the days the year has had so far: today's date in the current year, the whole year for a year that is over. The strip under it is every coloured day sorted by mood, each mood's share of the strip being its share of the coloured days. The small mark under each month is that month's most common mood; a tie goes to the harder of the tied moods, so a mixed month is never shown as better than it was.

The five moods and their colours are ours: five warm tones, dark to light, so the scale still reads as five steps in grey. Every name and colour can be changed. The printed sheet is laid out at the true size of the paper, converting millimetres at the CSS definition of 96 pixels to the inch, and the image is drawn in the page at 1080 by 1350 pixels. Your colours are kept in this browser's local storage under one key, and the backup button writes the same data to a file.

How to read a year in pixels

A year in pixels is a mood tracker drawn as one grid of 365 squares. You colour one square each evening for the day just gone, and after a few months the page shows the shape of the year — the grey fortnight in February, the good run in June — as a picture rather than a vague recollection.

Read the grid down, not across. Each column is a month and each row is a date, so a hard patch shows as a dark band running down one column. Read across a row and you are comparing the same date in every month, which is a rough way to see whether, say, the last week of the month is always the tired one.

Five moods is enough. Three cannot tell a flat day from a bad one, and ten turn a four-second choice into a debate. The names are yours to change: energy, pain, sleep or anxiety work on the same five steps, and the colours change with them.

Keep the grid where you will see it. This one is saved in this browser; the printed sheet can go inside a cupboard door. If you would rather have a month to a page with room for habits, the printable mood tracker prints one. The life calendar uses the same one-square idea for a whole life in weeks, and year in progress shows how much of this year is still to colour. For what sleep, movement and company do to mood, read the mental health and daily habits guide. A grid of colours is a record, not a diagnosis; if the squares stay dark for weeks, show them to a doctor or someone you trust.

Frequently Asked Questions

What is a year in pixels?

A year in pixels is a mood tracker drawn as one grid: twelve columns, one per month, and thirty-one rows, one per day. Each evening you colour the square for the day just gone in the colour of its mood. After a few months the grid shows the shape of your year on a single page.

How do I fill in this year in pixels?

Tap a day and pick one of the five moods; the square takes that colour. Tap it again to change it or clear it. On a keyboard, the arrow keys move between days and the keys 1 to 5 colour the one you are on. Days after today are locked, because a mood is something you record, not something you plan.

Where is my year saved?

In this browser, on this device. There is no account, so the colours do not follow you to another phone or computer, and clearing your browser data clears them. The backup button downloads a small file you can load back in here, on this device or another one.

Can I change the moods and the colours?

Yes. The five moods start as Rough, Low, Okay, Good and Great in five warm tones, and every name and every colour in the key can be changed. The grid, the printed sheet and the image all redraw in your colours. Some people track energy, sleep, pain or anxiety on the same five steps instead.

Can I print a blank year in pixels?

Yes. The print section below the grid makes a one-page sheet for A4 or US Letter, either blank for colouring in by hand or filled with the days you have already coloured here. Press print and choose Save as PDF in the print dialog if you want a file instead of paper.

Why are some squares missing from the grid?

Because not every month has thirty-one days. Twelve columns of thirty-one rows is 372 squares, and a year has 365. February loses three squares (two in a leap year), and April, June, September and November lose one each, so seven squares are left empty in a normal year and six in a leap year.

Does tracking your mood like this actually help?

It is a record, not a treatment, and nothing here is a clinical instrument. What it gives you is a page instead of a memory: which weeks were heavy, when things turned, what else was going on. That is easier to read than recall, and easier to bring to a doctor or therapist if you are already seeing one.
