Where this calendar’s listings come from.

Championships

USA Curling's event locator for the national championships, playdowns and qualifiers; World Curling's results database for the world championships; the Grand Slam of Curling's season list for the Slams.

Bonspiels & clubs

The bonspiels clubs list with USA Curling, by club (Evergreen) or by region, and its course listings for the officials, instructor, coaching and ice-technician courses; Granite Curling Club's own bonspiel page and its public calendar; the Grand National Curling Club's calendar for the Northeast; and the calendars ninety clubs publish on their own sites (Curling Club Manager, Curling I/O, Google Calendar, The Events Calendar, Eventbrite, Squarespace) — bonspiels, learn-to-curls, open houses, clinics and courses, each on its region's row with the club's town.

Local Clubs

Every US club from USA Curling's club finder and the regional associations' member lists (236 clubs). Your location, when you allow it, stays in your browser; ZIP code positions are the GeoNames postal-code centroids (CC BY 4.0).

The map

The countries, the great lakes and the state lines are from Natural Earth (public domain), drawn here as one file made at build time — no map tiles, nothing fetched from anywhere else. Each event is pinned to the town its listing names, located once through OpenStreetMap’s Nominatim (© OpenStreetMap contributors, ODbL); a town the gazetteer has not learnt yet is listed but not pinned.

The final word

Refreshed once a day. Every listing links to the event, its entry page or its organiser — check there before you go.
