Sevens is a stripped-down version of rugby union, with seven players on each side rather than fifteen. Games are much shorter, seven or ten minutes each half, and tend to be very fast-paced. Sevens is traditionally played in a two-day tournament format; however, the most famous event, the Hong Kong Sevens, is played over three days.
The series' tournaments are identical to 2007–2008 and span the globe:
| Dubai | The Sevens | November 28–29, 2008 | |
| South Africa | Outeniqua Park, George | December 5–6, 2008 | |
| New Zealand | Westpac Stadium, Wellington | February 6–7, 2009 | |
| United States | PETCO Park, San Diego, California | February 14–15, 2009 | |
| Hong Kong | Hong Kong Stadium | March 27–29, 2009 | |
| Australia | Adelaide Oval, Adelaide | April 4–5, 2009 | |
| London | Twickenham | May 23–24, 2009 | |
| Scotland | Murrayfield, Edinburgh | May 30–31, 2009 |
The 2009 Rugby World Cup Sevens is not a part of the 2008-09 series. Unlike the 2005 edition held in Hong Kong, the 2009 edition will not replace one of the 2008-09 series events. The World Cup will be held in Dubai from March 5-7 2009.
Points are awarded on a different schedule for the Hong Kong Sevens:
Four trophies are awarded in each tournament, except for Hong Kong. In descending order of prestige, they are the Cup, whose winner is the overall tournament champion, Plate, Bowl and Shield. In Hong Kong, the Shield is not awarded. Each trophy is awarded at the end of a knockout tournament.
In a 16 team tournament, the top two teams in each pool advance to the Cup competition. The four quarterfinal losers drop into the bracket for the Plate. The Bowl is contested by the third-place finishers in each pool, while the Shield is contested by the last-place teams from each pool. In Hong Kong, the six pool winners, plus the two highest-finishing second-place teams, advance to the Cup. The Plate participants are the eight highest-ranked teams remaining, while the lowest eight drop to the Bowl.
