About this site

Method

Dates, places, times, costs, rules and causes are quoted from each event’s own page or its organizer’s, in quotation marks with a link. Before each update a script fetches every page again, with a User-Agent that names this site, and checks each quote word for word; anything it can’t find comes off the site. The last full check was November 2, 2026.

An event goes in this winter’s calendar only when its own page prints this winter’s date. Event pages that give a day without a year, and events held last winter that haven’t posted a new date, are listed separately. We don’t use social media or news stories as sources. The headings and the city and region on each listing are ours, taken from the event’s page.
