Sleet coming sideways across Twickenham on the first Saturday of February, 82,000 people in coats, two sides kicking for territory because nobody can hold the ball. That is one of these tournaments. The other is a Saturday afternoon at Ellis Park in Johannesburg, roughly 1,700 metres above sea level, where the ball flies further through thin air than it has any business doing and a scrum-half's box kick lands twelve metres past where he meant it to.
British viewers watch both. Very few people can explain, off the top of their head, why one runs to five rounds and the other to six, why the Six Nations had to invent a Grand Slam bonus and SANZAAR never did, or why England have never played in the southern competition and never will. Those differences are not accidents of scheduling. Each one follows from geography, from the club season underneath it, and from who owns the tournament.
Six teams against four, and how each field was assembled
The Six Nations is England, France, Ireland, Italy, Scotland and Wales, and it is the oldest international tournament in the sport. It began in 1883 as the Home Nations Championship between the four British and Irish unions. France joined in 1910 to make it Five Nations, were expelled in 1932 over allegations of professionalism in the French club game, and returned in 1947. Italy were admitted in 2000. That is one addition in ninety years, which tells you how the competition thinks about itself.
The Rugby Championship is New Zealand, South Africa, Australia and Argentina. Its history is short and commercial: the Tri Nations was created in 1996, in the first year of professionalism, as part of the broadcast package that also produced the southern hemisphere's cross-border club competition. Argentina were admitted in 2012 and the tournament was renamed.
Neither has promotion or relegation, and neither has any published mechanism for adding a team. Georgia's case for a place in the Six Nations has been argued for the better part of two decades without a route existing to test it, and Fiji have made a comparable case in the south. Both tournaments are private competitions between unions that own them jointly, which is a different legal animal from a league.
Ownership matters for everything that follows. The Six Nations is run through a company in which the six unions hold stakes alongside an outside investor who bought in during 2021. The Rugby Championship is run by SANZAAR, a joint venture of the four southern unions. Two separate businesses, two separate broadcast markets, two separate sets of accounts — which is the honest answer to most questions about why they do not co-operate more than they do.
One round robin against two
Six teams playing each other once produces fifteen matches over five rounds. Four teams playing each other twice produces twelve matches over six rounds. The arithmetic is the whole difference in format, and almost every other structural contrast falls out of it.

Fixed structural figures for a standard edition. The Rugby Championship is shortened in Rugby World Cup years.
In the Six Nations each side plays five matches, and because the tournament is a single round robin the home and away pattern has to alternate year on year. England host France one season and travel the next. The consequence is that no edition is symmetrical: in any given year one team gets three home matches and another gets two, and which fixtures fall at home is decided by a rota fixed decades in advance. The mechanics of that rota, and its effect on who is favoured in a given year, are set out in the guide to the Six Nations fixture rota.
The Rugby Championship has no such problem. Six matches, three at home and three away, every side balanced against every other. In a World Cup year the format collapses to a single round robin of three matches each so the four unions have a clean preparation block, which means the shortened editions are the ones with a home-and-away imbalance.
There is a knock-on effect on how a title gets decided. Five matches leaves very little room for a bad afternoon, and Six Nations titles have repeatedly turned on points difference in the final round; six matches gives a side one more chance to recover. The full ordering of the Six Nations tie-breaks is covered in the tie-break rules.
February in Europe, mid-season in the south
The Six Nations runs from the opening weekend of February to a closing Saturday in mid-March. It sits in the middle of the northern club season, which is the source of every player-release argument in European rugby: a Premiership or Top 14 club releases its internationals for seven weeks in the heart of its own campaign and gets them back with the mileage on them.
The Rugby Championship sits after the southern cross-border club season has finished, broadly across July to late September, though the window has been redrawn more than once as World Rugby has revised the global calendar. That timing means the southern unions get their players fresher, out of a completed club season rather than in the middle of one, and it explains why southern squads arrive in November having already had a long block together.
For an English supporter the practical consequence is scheduling. Six Nations kick-offs are at times built for a Saturday afternoon or evening in Britain. Rugby Championship kick-offs are at times built for Auckland, Brisbane, Buenos Aires and Cape Town, which in the UK means a morning television slot for the Australasian matches and an early evening one for the South African ones. Very few British viewers watch a full Rugby Championship round live. Almost all of them watch a full Six Nations round.
Why the two calendars cannot simply be swapped
Seasons run in opposite directions. A July Test in London falls in the English off-season; a February Test in Wellington falls in the New Zealand summer, before Super Rugby has finished. Any proposal to merge the tournaments has to solve that, and no version yet proposed has.
Bonus points, and the clause the Six Nations had to add
Both competitions run the standard four-point win, two-point draw, and both attach the same two bonus points: one for scoring four tries in a match, one for losing by seven points or fewer.
| Element | Six Nations | Rugby Championship |
|---|---|---|
| Win | 4 points | 4 points |
| Draw | 2 points | 2 points |
| Try bonus | 4 tries in a match | 4 tries in a match |
| Losing bonus | Defeat by 7 points or fewer | Defeat by 7 points or fewer |
| Grand Slam bonus | 3 extra points for winning all five | Not applicable |
| Bonus points introduced | 2017 | From the tournament's creation in 1996 |
The Six Nations resisted bonus points for two decades and adopted them in 2017. The reason for the delay was a specific and legitimate worry: with only five matches, a side could win all five and still be caught by a team that had lost once and collected try bonuses. So the Six Nations wrote in a clause giving a Grand Slam winner three extra points, which mathematically removes that outcome.
The Rugby Championship never needed the clause because a four-team double round robin makes a clean sweep of six matches almost impossible to out-score. The southern competition also came into existence in the professional era, when bonus points were already normal, so it never had to argue about them. A fuller account of how the northern system works in practice is in the guide to the Six Nations bonus point system, and the Grand Slam itself is covered here.
One honest caveat: the four-try threshold has been reviewed by both competitions and by other tournaments, with proposals to make the bonus conditional on out-scoring the opponent rather than on an absolute count. Neither of these two has changed it, but the rule is not carved in stone.
Distance, time zones and what a Rugby Championship week actually costs
Rome to Dublin is under three hours in the air. Paris to Edinburgh is less. The widest time gap inside the Six Nations is a single hour, between Britain and Ireland on one side and France and Italy on the other. A Six Nations squad flies out on Thursday and plays on Saturday, and jet lag is not a factor anybody in the northern game has to plan for.
Now the south. Buenos Aires to Auckland crosses the Pacific and is among the longest scheduled routes in world sport. Johannesburg to Buenos Aires crosses the South Atlantic. Perth to Wellington, Cape Town to Brisbane — a Rugby Championship campaign can involve time-zone shifts of eight to eleven hours and multiple crossings of the equator's worth of climate change within six weeks.
That produces measures the northern game never has to take. Southern squads travel earlier, sometimes a full week before a match. They build blocks so that two away matches happen on one trip rather than two. Argentina in particular has spent much of its Rugby Championship existence effectively on tour, because its domestic base sits nowhere near the other three.
The competitive effect is real and hard to quantify. Home advantage in the Rugby Championship carries a travel penalty for the visitor that home advantage in the Six Nations does not, which is one reason the World Rugby rankings apply a fixed home-advantage adjustment rather than trying to model each fixture.
Supporters feel the same asymmetry from the other end. A Scotland follower can be in Rome for a Saturday afternoon on a budget airline and home on Sunday night, and the Six Nations away support that fills the corners of the Stadio Olimpico or the Aviva is a visible part of what the tournament is. Away support in the Rugby Championship is a different proposition entirely, priced in long-haul fares and annual leave, so southern grounds carry far less travelling colour than a Six Nations fixture does. That has commercial consequences for the tournaments as well as atmospheric ones.
There is a competition-integrity angle too. A double round robin over six rounds means every side takes the same long flights in the same tournament, so the travel burden is at least distributed evenly. In the Six Nations, where the home and away pattern alternates, the imbalance is in fixtures rather than in distance — nobody's preparation is compromised by a flight, but somebody every year gets Paris and Dublin away in the same campaign.
Wet pitches, thin air and the styles each produces
Cardiff has a roof. It is the only Six Nations ground that does, which means the Principality Stadium is the one venue in the tournament where a wet Saturday does not automatically produce a kicking contest. Twickenham, the Stade de France, Murrayfield, the Aviva Stadium and the Stadio Olimpico are all open to whatever a European February sends.
What that produces on the field is well known to anyone who has sat through a 9-6 in the rain: heavier pitches, a slower ball, more contestable kicking, more set piece, and a premium on a pack that can hold a scrum in mud. Sides that want to move the ball in February have to earn dry conditions or wait for March, and the fifth round is often visibly faster rugby than the first.
The Rugby Championship has its own conditions problem, and it runs the other way. Johannesburg and Pretoria sit at altitude, where the ball travels further and recovery between phases is harder for a visiting side. Auckland and Brisbane are humid rather than cold. The southern game's reputation for width is partly cultural and partly a description of the surfaces it is played on.
None of this is destiny. Ireland and France have both built high-tempo attacking systems that hold up in a northern winter, and South Africa have won World Cups playing a game that would be recognisable at a Championship match in Newcastle in February. Conditions bias a style; they do not dictate one.
Trophies inside trophies
Both competitions carry side-prizes, and the Six Nations carries far more of them because it has had a century longer to accumulate them.
| Fixture | Trophy |
|---|---|
| England v Scotland | Calcutta Cup, contested since 1879 |
| England v Ireland | Millennium Trophy |
| Scotland v Ireland | Centenary Quaich |
| France v Italy | Giuseppe Garibaldi Trophy |
| France v Scotland | Auld Alliance Trophy |
| Scotland v Wales | Doddie Weir Cup |
| Scotland v Italy | Cuttitta Cup |
| New Zealand v Australia | Bledisloe Cup, contested since 1931 |
| New Zealand v South Africa | Freedom Cup |
| Australia v South Africa | Mandela Challenge Plate |
| Australia v Argentina | Puma Trophy |
Above those sit the tournament trophies themselves, and above the Six Nations table sit two prizes that exist only in the north: the Grand Slam for winning all five, and the Triple Crown, available to England, Ireland, Scotland or Wales for beating the other three. There is no southern equivalent to either, because with four teams a clean sweep and a title are the same thing.
The Wooden Spoon is the other northern peculiarity — an unofficial prize for finishing last that nobody awards and everybody counts. The Calcutta Cup, made from melted-down silver rupees when the Calcutta club disbanded in 1878, is the oldest of the lot and has its own history worth reading.
The Bledisloe Cup is worth one note of difference. It is contested over a series rather than a single fixture, and that series has sometimes included matches played outside the Rugby Championship window, so a side can win the Championship and lose the Bledisloe in the same year.
Crowds, capacity and where a British viewer finds each one
Twickenham holds around 82,000 and is the largest stadium in the world built specifically for rugby union. The Stade de France and the Principality Stadium are in the seventies and eighties of thousands. Murrayfield is in the sixties. Every Six Nations home fixture at those grounds sells out, and has done for years, which is why the ticket ballot exists in the form it does.
Southern venues are smaller. Eden Park, Suncorp Stadium and the regular Argentine venues seat well under Twickenham's capacity, and South Africa is the exception that periodically moves a Test into a football stadium of ninety thousand. Attendance across the Rugby Championship is respectable and structurally capped by the buildings available.
Broadcast is the sharper contrast for a reader in England. The Six Nations has been carried free-to-air in the UK, shared between the BBC and ITV, which is the single largest reason the tournament reaches audiences that no other rugby competition touches — a Calcutta Cup Saturday pulls in people who watch no other rugby all year. The Rugby Championship has been a subscription proposition in Britain. Rights deals change, so treat the specific arrangement as a moving target rather than a fixed fact, but the pattern has held for a long time and it explains the gulf in casual awareness between the two.
The autumn, the summer tour and where the hemispheres actually meet
England do not play in the Rugby Championship. The crossover happens in two windows, and they are the reason November at Twickenham matters as much as it does.
- February to MarchThe Six Nations. Five matches over seven weeks, in the middle of the Premiership season.
- JulyThe summer tour window. England travel, most often to the southern hemisphere, for a two or three Test series.
- July to SeptemberThe Rugby Championship runs in the south while the northern game is out of season.
- NovemberThe Autumn Nations Series. England host southern hemisphere and emerging sides at Twickenham across consecutive weekends.
- World Cup yearsThe July window shortens, the Rugby Championship is cut to a single round robin, and the tournament follows in September and October.
The structure of the annual Test calendar as it applies to England. Individual fixtures and opponents are agreed years in advance and vary by year.
The July tour is the harder of the two for England. A side that has finished a Premiership season and a Six Nations flies south to play teams in the middle of their own competitive block, at altitude or in humidity, often with front-line players rested or unavailable. Results on those tours are historically poor for northern sides and the context is usually more forgiving than the scoreline.
November reverses it. Southern sides arrive at Twickenham at the end of a long year having crossed the equator, and northern sides are fresh into their season. England have taken some of their best results in that window, and the autumn internationals have their own guide covering how the fixtures are agreed and why they are not treated as a tournament.
Rankings, seeding and why a February result matters in 2031
Both tournaments feed the same table. World Rugby's rankings work as a points exchange between the two sides in every full international: the winner takes points from the loser, the amount varying with the gap in rating between them, with an adjustment applied for home advantage and a larger transfer for a win by more than fifteen points. World Cup matches carry double weight.
The reason this matters more than a leaderboard usually does is the draw. Rugby World Cup pools have historically been drawn from ranking bands on a fixed cut-off date well before the tournament — in some cycles two or three years before. A side that has a poor Six Nations in the wrong February can drop a band and find itself in a pool with two of the top four, and that has happened to more than one major nation.
The Rugby Championship's four teams trade points among themselves in a closed group of high-ranked sides, which tends to move ratings less violently than the Six Nations does, where the spread of ratings across six teams is wider and an upset transfers more. It is a subtle asymmetry and it is the technical reason results in the two tournaments do not carry identical ranking weight.
With the men's World Cup expanding to twenty-four teams, the pool structure changes and the seeding arithmetic changes with it. How the bands are constructed for an expanded tournament is a detail worth checking against World Rugby's published tournament rules rather than assuming it works as before.
The double weighting on World Cup matches produces one effect worth understanding, because it distorts comparisons between the tournaments. A pool win at a World Cup moves a rating roughly twice as far as the same win would in a February Six Nations fixture, which means a good six weeks in September can undo two years of Championship results and vice versa. For a British reader trying to work out whether a Six Nations placing has "cost" England anything, the honest answer is that it depends entirely on where the next ranking cut-off falls and how close the side is to a band boundary.
There is also a floor effect nobody talks about. Because the exchange scales with the gap between the two sides, a top-five nation beating a side ranked twentieth gains almost nothing and loses a great deal by slipping up. The Rugby Championship, played entirely between high-ranked teams, is therefore a low-variance environment for its participants. The Six Nations, with a wider spread, hands out larger swings in both directions — which is another way of saying that an upset in Rome or Edinburgh reverberates through a World Cup draw in a way an upset in Brisbane does not.
Which is harder to win
A four-team tournament in which every opponent has been world champion or a World Cup finalist is a brutal thing to win. There is no fixture in the Rugby Championship where a coach can rest half a pack. New Zealand's dominance of the Tri Nations and Championship across its history is the most sustained run of success in any international rugby competition, and it was achieved against a field with no soft edges.
Set against that, the Six Nations asks for five wins in seven weeks in a northern winter, including trips to grounds where the crowd is a genuine factor and where the home side's whole season is compressed into one afternoon. Grand Slams are rare for a reason. Ireland at the Aviva in a March closing round, Wales in Cardiff with the roof shut and the anthem still going — those are environments the southern game has no direct equivalent to, because its away crowds are smaller and its fixtures are spread across six rounds rather than five.
My view, offered as a judgement rather than a fact: the Rugby Championship is harder to win on pure playing standard, and the Six Nations is harder to win without dropping a match, because five rounds with no margin and hostile February away days punishes a single bad hour more severely. Anyone who tells you one is definitively superior is arguing about something other than rugby. The closing weekend of the northern tournament, Super Saturday, is the single best argument for the Six Nations format, and it exists only because five rounds leave so many outcomes alive.
Why they have not merged, and what a Nations Championship would change
Four obstacles, in rough order of stubbornness.
Ownership is the first. Two separate commercial entities with two separate broadcast contracts and two separate sets of union finances would each have to give something up, and the northern unions in particular depend on Six Nations revenue to fund their community game.
Seasons are the second. The northern club season runs September to June and the southern one runs February to June, so there is no shared free window long enough for an expanded tournament without breaking one of the club competitions.
Travel is the third, and it is not just about players. A merged tournament means supporters flying eleven thousand miles for an away weekend, which nobody has costed honestly.
Tradition is the fourth. The Six Nations is one hundred and forty years old and its fixtures are family events. Any restructure that dilutes England v Scotland or Wales v France to make room for a global format would have to be sold to people who have been going for fifty years.
World Rugby's answer has been a Nations Championship — a competition that keeps both tournaments intact and stacks a further layer on top, using the existing July and November windows as cross-hemisphere rounds and finishing with a decider. The announced shape has been revised more than once during its development, so the sensible position is to treat the concept as settled and the detail as provisional. The important structural point is that it does not merge anything. It monetises the fixtures England already play in July and November and gives them a table.
Which leaves the answer to the original question intact. The Six Nations and the Rugby Championship remain two different competitions, run by two different bodies, in two different halves of the year, and the only place they genuinely collide is a Saturday in November at Twickenham. More of this section's rugby guides sit on the England hub, and the rugby coverage runs alongside them.
