Independent sports reference Competition formats, qualification and calendars explained.

Sport hubs

All sports

Each hub explains one sport's competitive landscape: which competitions exist, how a season is shaped, how teams qualify for what comes next, and where the authoritative rules live. Figures that change carry the date they were checked.

League and competition hubs

Specific competitions, with their structure and post-season format explained.

Sport hubs

The sport itself across every level of competition, rather than one league.

Season planning

How to read these hubs

Durable structure

What a group stage is, why divisions exist, how a two-legged tie is decided, what promotion and relegation mean. These change rarely and are explained without dates.

Dated figures

Club counts, playoff field sizes and qualification places do change. Where a hub states one, it also states the date it was checked and the body to re-check it with.

What these hubs are not

They are not predictions, previews, tips or rankings, and they are not a schedule service. Fixtures, results and standings change continuously, so this site points you to the competition's own schedule rather than mirroring it — a mirrored table is out of date the moment it is published.
