Six Nations & Northern Hemisphere Period
The Northern Hemisphere international period begins in early February. The Six Nations sits at the center of this part of the rugby calendar.

How Does the Rugby Calendar Work?
Rugby does not have one worldwide season. International windows, domestic leagues, cross-border club competitions, sevens and major tournaments all operate on different calendars. Here is how the rugby year fits together.

01
THE SIMPLE ANSWER
When Is Rugby Season?
There is no single global rugby season.
Rugby is played somewhere in the world during almost every part of the year because the Northern and Southern Hemispheres operate on different seasonal schedules.
European club competitions generally run across the Northern Hemisphere autumn, winter and spring, while major Southern Hemisphere competitions follow a different calendar. International rugby is then layered around and, at times, on top of those club seasons.
The easiest way to think about it:
rugby has a global calendar made up of overlapping club,
international and sevens seasons rather than one universal season.

TEST RUGBY
What Are International Rugby Windows?
International windows are defined periods in the global rugby calendar when national teams play Test matches, tours and international tournaments.
They matter because many international players are contracted to professional clubs. World Rugby Regulation 9 sets out when eligible players must be released for international duty.
Global July Window
World Rugby provides a three-weekend global release window in July. From 2026, the men's Nations Championship uses this established international period.
Rugby Championship Period
The Rugby Championship release period ordinarily begins around the second weekend of August and operates across an eight-week period.
Global November Window
November contains another major global international release period. The men's Nations Championship also uses this window from 2026.
What changed in 2026?
The new men's Nations Championship was built into the existing
July and November international windows rather than creating an
entirely separate part of the season.
04
TWO DIFFERENT RHYTHMS
Why Do the Northern and Southern Hemispheres Have Different Seasons?
One of the keys to understanding rugby is recognizing that professional competitions do not all operate on the same seasonal calendar.
NORTHERN HEMISPHERE
Autumn to Spring
Major European professional competitions generally begin later in the calendar year and continue through the following spring.
- PREM Rugby
- United Rugby Championship
- Top 14
- European club competitions
SOUTHERN HEMISPHERE
Different Seasonal Cycle
Major Southern Hemisphere competitions operate on a calendar that reflects their seasons and international schedule.
- Super Rugby Pacific
- Domestic competitions
- Rugby Championship period
- Mid-year international rugby

ANNUAL INTERNATIONAL RUGBY
When Are the Six Nations and Rugby Championship Played?
Six Nations
England, France, Ireland, Italy, Scotland and Wales compete during the Northern Hemisphere's traditional early-year international period.
VS
Rugby Championship
The Rugby Championship occupies a later part of the year. World Rugby's release period ordinarily begins around the second weekend of August and operates for eight weeks.
The different timing of Northern and Southern Hemisphere international competitions is one reason Test rugby appears throughout so much of the calendar year.
06
MAJOR TOURNAMENT CYCLES
Where Do the Rugby World Cups Fit?
Rugby World Cups sit above the normal annual Test calendar. They are major international events that can reshape the season around them through warm-up matches, preparation camps, player management and tournament windows.
The men's and women's Rugby World Cups each operate on their own multi-year cycles, so they should not be treated as one single four-year global calendar.
MEN'S RUGBY WORLD CUP
Four-Year Cycle
The Men's Rugby World Cup is staged every four years and becomes the central event of the men's international season in a World Cup year.

WOMEN'S RUGBY WORLD CUP
Separate Tournament Cycle
The Women's Rugby World Cup operates on its own tournament schedule. Its timing does not always line up with the men's event, so the two competitions should be viewed as separate parts of the global rugby calendar.
CALENDAR EFFECTInternational preparation + tournament window
1Warm-up Tests
National teams often schedule preparation matches before a World Cup.
2Training Camps
Players may leave club environments earlier than during a normal international window.
3Tournament Window
The World Cup itself occupies a major block of the international calendar.
4Club Calendar Effects
Domestic competitions can adjust start dates, schedules or player availability around the tournament.
The key point:
there is no single "World Cup year" for all of rugby. Men's and
women's tournaments sit on separate cycles and affect their
respective international calendars differently.
07
ANOTHER CALENDAR
Where Does Rugby Sevens Fit?
Rugby sevens has its own international competition calendar, which runs alongside the fifteen-a-side game.
International sevens includes a global series of tournaments as well as major events such as the Olympic Games and Rugby World Cup Sevens.
That means a weekend can feature professional club rugby,
Test rugby and international sevens at the same time.
08
WHY IT GETS CONFUSING
Why Do Club and International Rugby Overlap?
Unlike sports built around one domestic league and one national season, rugby has several major competition structures operating simultaneously.

Depending on the competition, clubs may continue playing while some internationals are away, adjust their schedules, or pause around particular international periods.

THE USA PICTURE
How Does the Rugby Calendar Work in the United States?
The United States adds another layer because international, college, club and sevens rugby can all operate on different schedules.
USA Eagles
The USA men's and women's national teams follow international competition and Test windows.
College Rugby
College competitions operate around the U.S. academic calendar, with different structures across organizations and divisions.
Club Rugby
Senior club competitions vary by region, division and governing competition, creating both fall and spring activity across the United States.
Sevens
Domestic and international sevens adds another set of tournaments to the American rugby year.
10
PUTTING IT TOGETHER
Why Is Rugby Played Almost All Year?
Because there is no single global season.
When one competition reaches its offseason, another part of the rugby world may be starting its season, entering an international window or beginning a sevens tournament.
THE BIG IDEA
Rugby is not one season. It is a collection of overlapping
seasons connected by a global international calendar.
