Kenyan Constitution requires a general election on the second Tuesday in August in every fifth year.
 There have been public discussions to move the date from August to December with proponents pointing to fiscal timeline (1 July – 30 June) clashing with an August date because most ministries that support critical election processes will not have been fully funded and that a possible presidential runoff vote may interfere with the national examinations calendar of October and December.
 Opponents of the election date change have argued for protecting the constitutional provision and that any change would be mired by legal challenges and might drag on to the next elections and still require a referendum to decide, putting the country's stability at risk.
On 7 August 2017, one day before the election,
Barack Obama, who served as the 44th President of the United States from 2009 to 2017 and whose father,
Barack Obama Sr., was Kenyan, called for calm and acceptance of the election results.
 The intervention was noted by the media as unprecedented.
