层级
Dates and structural facts come first from organizers’ official websites, then from governing bodies (the FIA, ATP and WTA, ITF, R&A, USGA, British Horseracing Authority, FEI, Fédération Française de Voile and their peers), then from venues and government tourism organizations. Recognized publications are used for the public dimension of an event — the programme around it, reported changes — and are named. Every event and destination page lists its sources with the date they were accessed.
资讯
The news feed aggregates headlines from named publishers’ own RSS feeds — sport, arts, fashion and travel desks — and from Google News queries for the major events, always linking to the original article. Headlines and summaries remain the publishers’ property. Items older than 120 days are removed.
气候
Weather-by-month tables use long-term averages from the source named beneath each table, usually the national meteorological service via Wikipedia’s climate tables. They describe a typical year, not a forecast.
地理
Maps are drawn from Natural Earth public-domain outlines on a plain equirectangular projection; pins use the venue coordinates recorded for each event and destination.
