Plan how long your tournament needs.

Round robin if everyone should play everyone and there is time for it. Knockout if the calendar is tight and a single loss ending a team is acceptable. Groups plus knockout is the middle ground: teams play a handful of guaranteed matches in a group, then a shorter bracket decides the rest, which is why it is the format most tournaments above about 10 teams actually use.

Yes, a power of two: 4, 8, 16, 32. CricketOrganizer’s knockout generator requires it, and if a knockout stage is created with any other count, that stage produces no matches at all rather than guessing. Round up to the next power of two and give the extra slots byes into round two, which is what this calculator does automatically.

Not yet. Only single elimination is implemented; a loss ends a team’s tournament. If that is too harsh for the stage you are running, a group stage ahead of the knockout gives every team more than one match before it can be eliminated.

Whichever is larger: total matches divided by how many a day your grounds can host, or the number of rounds a team has to play through, spaced by the rest it needs between them. Most organizers only check the first one and are surprised when the schedule still needs extra days for player recovery.

Only if grounds are the bottleneck. Once the schedule is bound by rest days instead, an idle second ground does nothing: a team still cannot play again until its rest period is over, whatever else is free. The calculator names which bound is actually in force.

It depends on the format and daylight, but two to three T20-length matches (about two to two and a half hours each with a change of innings) is a realistic day on one ground with lights. Push past that and the day runs late enough that the last match starts under a fatigue disadvantage the earlier ones did not have.

At grassroots pace, a day off between matches is a reasonable default for anyone playing weekends, more for a tournament run on consecutive days. The number that matters is not comfort but arithmetic: rest days multiply across every round, so a five-round league with two rest days between each round needs thirteen days, not five.

Because two different limits are both real. One is how fast your grounds can get through the matches. The other is how fast your players can safely play them. A schedule has to satisfy both, so the true minimum is whichever number is bigger, not whichever one you calculated first.

Only if your rest setting allows it, and rarely a good idea past one format’s length in overs. The calculator will let a rest value of zero produce that schedule, but a team playing two full matches back to back is a different tournament than the one most players signed up for.

One team sits out each round. CricketOrganizer’s round-robin generator adds a dummy opponent internally and simply skips any match against it, so the bye is automatic and the match count already accounts for it: seven teams play twenty-one matches, the same as an even eight minus the seven that would have involved the phantom team.

The knockout bracket rounds up to the next power of two regardless, and the extra seats become first-round byes. Three groups sending two qualifiers each is six teams, which rounds up to a bracket of eight with two byes straight into the semi-finals. Decide which two byes get that advantage before the group stage finishes, not after.

No. A bye is a team advancing because there was no opponent to schedule against it, decided by the bracket shape before a ball is bowled. A walkover is a scheduled match one side does not turn up for. The calculator only ever produces the first kind.
