Notes
- All of these are the dates for the Round 1, not signups
- SPL, OST, Smogon Tour 27 and Classic remain unchanged
- WCoP and SSD were slightly altered to create an equal eight-week break between the start and end of all team tours (not accounting for tiebreaks)
- The WCoP and SSD changes allows Grand Slam to start a little earlier and clash a little less with SSD
- PU Open will be replacing Ubers Open in Grand Slam VIII
- OLT starts after WCoP ends and the first three rounds of Swiss ends as SSD begins
- Smogon Tour 28 remains unchanged
