Almanac facts

Dates, names and events come from Wikidata, released into the public domain under CC0. Facts are not copyrightable in any case — no one owns the date of a battle.

Almanac descriptions

Where an entry carries a sentence describing what happened, that sentence is taken from Wikipedia's Selected anniversaries pages, and short biographical summaries come from the subject's own Wikipedia article. Both are used under CC BY-SA 4.0, which means you may reuse them on the same terms.

Anything we have written ourselves carries no such condition, and is marked as ours on the page.

Almanac pictures

Photographs and portraits come from Wikimedia Commons. Each one is credited beneath the picture with its photographer or artist and a link to its exact license, because those licenses differ file by file.

We only publish images that are public domain, CC0, CC BY or CC BY-SA. We do not publish anything licensed NonCommercial or NoDerivatives, and we do not use files hosted locally on Wikipedia under United States fair use — that claim belongs to Wikipedia and does not transfer to us. Where a license requires an author's name and Commons does not record one, the picture is not shown at all.

Linked stories

Headlines and standfirsts from other publishers are shown to point you at the original, which is always one click away and always opens on the publisher's own site. We do not reproduce their articles.

Weather

Forecasts are based on data from MET Norway (the Norwegian Meteorological Institute), from its weather API, under the NLOD 2.0 and CC BY 4.0. We show its temperatures rounded to whole degrees, work out each day's high and low from its hourly figures, and describe its weather symbols in our own words. MET Norway has no part in this site and does not endorse it.

In the longer forecast we convert its wind speed from meters a second to miles or kilometers an hour, and add up its hourly rain into a figure for each day. Today's figure counts only the hours still to come. Where MET Norway gives a chance of rain, which it does for the Nordic countries, a day shows the highest chance in any part of that day; everywhere else it shows the amount, and we do not estimate a chance ourselves.

The weather icons are Meteocons by Bas Milius, used under the MIT license. Their shapes are unchanged; we set their colors so that they stay readable on a light and on a dark page.

Place names and their positions come from GeoNames, under CC BY 4.0. We keep each place's name, region, country, time zone and population, with its position rounded to two decimal places.
