Work out league fixture count instantly with clear inputs, formula shown and shareable results.
Fixtures are the round robin count n x (n - 1) / 2 times the number of meetings per pair, and matchdays are that total divided by how many games can run at once. A twenty team double round robin is 380 fixtures across 38 matchdays, which is why expanding a league quickly runs into calendar rather than sporting limits.
