Question: Which traditional event that began on 26 December did the Pakistani cricket team replace with a tour of South Africa during the 2012-13 cricket season?
Context: The Pakistani cricket team are touring South Africa from 1 February to 24 March 2013.  The tour will consist of two Twenty20 Internationals (T20Is), three Test matches and five One Day Internationals (ODIs).  South Africa announced their summer schedule of January–March in which they replaced their traditional Boxing Day Test with a T20I for the 2012–13 home season, during which they will host New Zealand and Pakistan. International cricket played in the 2006 cricket season is defined as matches scheduled between May and August 2006 in all cricketing countries, as well as all international matches scheduled for the 2006 English cricket season.  Matches between January and April are defined as belonging to the 2005–06 season, while matches between September and December are defined as the 2006–07 season.  The main matches in this period were played in England, as this was in the middle of the English cricket season, but the third edition of the ICC Intercontinental Cup is defined as a part of the 2006 season, even though the tournament will stretch into February 2007, and three A teams are also scheduled to tour the northwestern part of Australia in June and July 2006. The Boxing Day Test match is a cricket Test match held in Melbourne, Victoria, Australia involving the Australian cricket team and an opposing national team which is touring Australia during the southern summer.  It begins annually on Boxing Day (26 December) and is played at the Melbourne Cricket Ground (MCG). The Centrals cricket team is a former Zimbabwean cricket club based in Kwekwe, Midlands Province.  The club was formed for the 2006–07 Zimbabwean cricket season, when Zimbabwe Cricket revamped the first-class domestic teams after the 2005–06 Logan Cup had to be cancelled due to internal strife.  The team played for three seasons, until the national cricket board decided to change the domestic format once again prior to the 2009–10 Zimbabwean cricket season, following recommendations from the International Cricket Council. The Pakistani cricket team toured England in the 2006 English cricket season, following England's winter tour of Pakistan where Pakistan had won a three-Test series 2–0 and the ODI series 4–1.  As a result of this series, Pakistan rose two spots to be ranked second in the world Test rankings before this series, and England dropped to third after the 12 July annual update of the ICC Test Championship.  The series was marred by a ball-tampering controversy on the fourth day of the Fourth Test, which culminated in Pakistan refusing to take the field after the tea interval in protest to a contentious decision by the umpires to penalise the Pakistani team for what they believed were acts of ball-tampering.  This led the umpires to award the game to England, who thus won the Test series 3–0.  In 2008, the ICC controversially declared the result of the final Test as a draw, altering the scoreline to 2–0; however, after criticism, not least by the MCC, this was subsequently reversed in February 2009 and the result restored as an England victory. Cricket is a popular sport in the United Arab Emirates.  The country currently hosts the matches of Pakistani cricket team due to the Lahore attacks on the Sri Lankan cricket team.  UAE has participated in various competition by International Cricket Council (ICC) and is an associate member of the ICC.  The country will also host few games for UAE cricket team (Home Leg) and Afghanistan cricket team at Sharjah Cricket Association Stadium, Sharjah in 2011–13 ICC Intercontinental Cup and 2011–13 ICC Intercontinental Cup One-Day.  The 2012 ICC World Twenty20 Qualifier is also scheduled in the United Arab Emirates at Dubai International Cricket Stadium, Dubai, ICC Global Cricket Academy (Oval 2), Dubai and Sharjah Cricket Stadium, Sharjah.  Currently Sheikh Zayed Stadium in Abu Dhabi, Dubai Sports City Cricket Stadium in Dubai and Sharjah Cricket Association Stadium in Sharjah are used by Pakistan for their international cricket matches. The South African cricket team toured India during the 1996–97 cricket season, playing three Test matches and one One Day International (ODI).  The tour was South Africa's second international cricket series in India, following a visit in 1991–92, and included their first Test appearances against India on the subcontinent.  India had previously toured South Africa in 1992–93, losing the Test series 0–1. The Indian cricket team toured South Africa during the 1996–97 season, playing three Tests from 26 December 1996 to 30 January 1997.  Prior to the series, India toured South Africa in the 1992–93 season, losing the Test series 0–1.  India was led by Sachin Tendulkar while South Africa was led by Hansie Cronje.  The series was Tendulkar's first overseas Test tour as captain and third overall.  The tour began with a Test series, consisting of three matches.  South Africa won the first two matches by a huge margin, thereby winning the series 2–1, while the final Test ended in a draw.  At the end of the series, Brian McMillan of South Africa emerged as the top run-scorer with 296 runs, with an average of 98.66.  He was closely followed by fellow team member Daryl Cullinan with 291 runs and India's Rahul Dravid (277 runs).  Allan Donald and Javagal Srinath finished the series as top wicket-takers capturing 20 and 18 wickets respectively.  The former was named "man of the series". The New Zealand national cricket team toured Pakistan during the 1996–97 cricket season.  The tour consisted of a first-class game against an invitational Pakistani Cricket board XI, followed by two Test matches and three One Day International games.  The hosts and tourists shared honours in the Test series, drawing 1–1, though Pakistan won with only a narrow 44-run margin in the first Test, and lost the second by an innings and ten runs.  New Zealand's Stephen Fleming enjoyed a successful series with the bat, scoring 182 runs at 60.66 in the Test series and 172 runs at 86.00 in the ODI matches, though the rest of the New Zealand batting line-up were said by the New Zealand press to have let the side down with the bat during the Test matches.  Nathan Astle, questioned over his place during the tour, redeemed himself with a half century in the final ODI match to alleviate heavy media pressure. The 2008–09 international cricket season was between September 2008 and March 2009.  The season saw the security concerns for cricket in Pakistan reach a pinnacle.  The ICC Champions Trophy, scheduled to be held in Pakistan in September 2008, was postponed to 2009 after five of the participating nations refused to send their teams for the event.  In November 2008, a Pakistani militant group launched terror attacks in Mumbai.  This led to India cancelling their tour of Pakistan originally scheduled for January and February 2009.  Sri Lanka agreed to tour Pakistan in place of India but the tour was jeopardised by a terror attack in Lahore where gunmen fired at a bus carrying the Sri Lankan team, injuring six members of the team.  The Champions Trophy was later relocated to South Africa and no international cricket were played in Pakistan for more than five years.  This period of isolation ended when Zimbabwe toured Pakistan in May 2015.
