Poster size

Pick your town and the year, and the poster draws all 365 days side by side: night at the top and bottom, the three twilights, and the daylight in the middle, swelling toward midsummer and shrinking toward midwinter. The times are your town's clock times, so the jump into and out of summer time shows as a step. Under the chart it names the longest and the shortest day, the earliest sunrise and the latest sunset; above the Arctic Circle it shows the midnight sun and the polar night. Tap any day for its sunrise, sunset and hours of daylight. Print it as a vector PDF from Letter to Tabloid, or keep it as a lock screen. Everything is computed in your browser.

Ideas for it

  1. A winter poster for the kitchen: watch the light come back day by day after December 21.
  2. A gift for someone who moved: the year of light in their new town next to the old one.
  3. A lock screen that shows how far the year has come.

The moon calendar poster draws the year’s Moon to go with it, and more for the coming year is on the New Year page.

Questions

How exact are the times?

Within about a minute of the almanacs. The Sun's position comes from the same series as the star map, sunrise and sunset are taken when the top of the Sun's disc meets the horizon (0.833° below it, with the bending of the light), and each time is worked out with the Sun as it is at that moment. For London in 2026 the tool gives sunrise at 04:43 and sunset at 21:21 on June 21, and 08:03 and 15:53 on December 21.

What are the bands of color?

From the middle out: daylight, when the Sun is up; civil twilight, until the Sun is 6° below the horizon, light enough to read outside; nautical twilight, to 12°, when the horizon fades at sea; astronomical twilight, to 18°; and night. In summer far north, twilight can last all night and the night band disappears.

Why is there a step in spring and in autumn?

That is summer time. The chart uses your town's clock, so when the clocks go forward in spring every sunrise and sunset jumps an hour later overnight, and back again in autumn. Places without summer time have a smooth curve.

What happens north of the Arctic Circle?

The poster shows it as it is: in Tromso, at 69.65° north, the Sun does not set around June 21 and does not rise around December 21, so those columns are all day or all night, and the line under the chart says so.

Is my location sent anywhere?

No. The list of towns is downloaded to your browser and searched there, and every time on the poster is computed on your device.
