First Standard Olympics
If the London Olympics had brought about a standardization of rules, the Stockholm Games brought about a standardization of the schedule. For the first time, a standard time frame was laid down and the entire event was conducted within a fortnight.
The opening ceremony of the Stockholm Olympics was conducted on July 6, 1912 and by July 22, the event was wrapped up. Since then, no Summer Olympics have stretched beyond 16-17 days.
Prior to that, the 1900 Paris Olympics had begun on May 14 and ended on October 28, while the St. Louis Olympics of 1904 ran from July 1 to November 23. The London Olympics of 1908 was the longest ever, beginning on April 27 and ending on October 31.
