<Li> July - The Open Championship ("The Open", sometimes called "the British Open" outside the UK) (weekend containing the 3rd Friday in July) - hosted by The R&A and always played on a links course at various locations in the UK </Li> <Li> August - PGA Championship (USPGA) (3rd weekend prior to Labor Day weekend) - hosted by the PGA of America and played at various locations in the USA . The PGA Championship will move to May beginning in 2019 . </Li> <P> The term "Grand Slam" was first applied to Bobby Jones' achievement of winning the four major golf events of 1930: The Open Championship, the U.S. Open, the U.S. Amateur and the British Amateur . When Jones won all four, the sports world searched for ways to capture the magnitude of his accomplishment . Up to that time, there was no term to describe such a feat because no one had thought it possible . The Atlanta Journal's O.B. Keeler dubbed it the "Grand Slam," borrowing a bridge term . George Trevor of the New York Sun wrote that Jones had "stormed the impregnable quadrilateral of golf ." Keeler would later write the words that would forever be linked to one of the greatest individual accomplishments in the history of sports: </P> <P> This victory, the fourth major title in the same season and in the space of four months, had now and for all time entrenched Bobby Jones safely within the' Impregnable Quadrilateral of Golf,' that granite fortress that he alone could take by escalade, and that others may attack in vain, forever . </P>

Has anyone won all 4 majors in the same year
