How were the changes found?
We started from the tournament map and its GeoJSON file. They list every ATP and WTA event we hold, with its city, surface and latest season. We then read each tour's 2026 and 2027 calendars on its official site and matched events by tour, tier and host city. An event whose tier or city changed counts as one dropped and one added, unless the official announcement says it is the same event. Its note then says so.
Six of the eight events are on the map from their latest season. The WTA Finals is there at Riyadh, its 2025 host, and the Manila WTA 250 is new.
Dates are the start dates the official calendars print. Surfaces come from those calendars too, because the map file does not split indoor from outdoor hard courts.
Calendars are provisional until the season starts. When a tour publishes a change, we read it again and update this page.
